Dental fillings linked to kids' behavior problems

Dental fillings linked to kids' behavior problems

Tooth decay is the most common chronic disease in the U.S. for kids. In fact, more than half of elementary school students will have cavities by the time they're in second grade, according to the National Institutes of Health. 

Since the 1970s, dentists have been using tooth-colored fillings that contain derivatives of the controversial chemical bisphenol A (BPA), in favor of the metal amalgam fillings.

Now a new analysis on dental fillings in children suggests these non-metal fillings may contribute to behavioral problems.  The study authors caution that their results only point to an association; they say their analysis does not prove that BPA causes any behavior changes.

Researchers looked at data from a previous study called The New England Children's Amalgam Trial, which was designed to examine the overall health effects of metal fillings in children, but also included children with composite or tooth-colored fillings. This study in particular was analyzed because it's really the only one looking at dental composites and behavioral problems, according to lead author Nancy N. Maserejian.

The scientists found that young people who got tooth-colored fillings made with BPA derivatives reported higher rates of anxiety, depression and social stress, compared to children whose fillings were made with metals or other materials. The more fillings a child had, the greater the incidence of behavioral problems, according to the data.

But the researchers are quick to point out that the levels of BPA were not measured in more than 400 children who participated in the study.

"There is a strong suggestion that the associations may be causal, but we can't be certain," says Maserejian, an epidemiologist with the New England Research Institutes. "More research is needed."

BPA is an industrial chemical that's been used in hard plastic products and in the linings of metal and aluminum cans since the 1960s.  Concerns about the effects of this chemical were raised as recently as 2008. That's when a report released by the  National Toxicology Program expressed “some concern for effects on the brain, behavior, and prostate gland in fetuses, infants, and children at current human exposures to bisphenol A.”

BPA has come under scrutiny for possible associations with a variety of health problems including developmental problems in young children and heart disease in adults.

This chemical is an endocrine disruptor, which means it interferes with how hormones work in the body.

In 2010 the U.S. Food and Drug Administration expressed the same concerns as the 2008 report.  Earlier this year, the FDA decided not to ban BPA in products made in the United States, cautioning that this announcement was not a final determination.  The FDA says it continues to support research examining the safety of BPA.

Experts speculate that dental patients may be exposed to BPA in two ways - when cavities are filled and various chemicals interact with our saliva, and/or over time as it leaches out due to wear and tear. 

When asked about the safety concerns due to BPA raised in this study, Michele Mummert, a spokesperson for Dentsply (a manufacturer of dental cavity composites) said: "Dental composites are one of several safe and effective options to treat tooth decay," and referred CNN to the American Dental Association's website for more information about dental treatment option.

Dr. Joel Berg is the president of the American Academy of Pediatric Dentistry. He supports the use of tooth-colored fillings because he says he knows they help children with cavities.

"Both amalgams and composites [tooth-colored fillings] are safe materials. They are both effective, they have been shown to be effective for years and years," explains Berg. "This is one study that has an early finding in the context of a larger group of studies looking at BPA, in a wide variety of materials where it's much more prevalent than in dental materials."

He also points out that the chemicals used in fillings are constantly improving and that what was used during the time of the original study (1997 to 2005) may be less safe than what we have today.

Frederick vom Saal, a biologist at the University of Missouri and a well-known critic of BPA, sees it differently. "This study provides evidence that the use of BPA-based composites should be re-evaluated."

Despite the lack of agreement on the safety of BPA, neglecting to treat cavities is dangerous and can lead to serious health issues for children, particularly from untreated infections.  Which is why Berg says getting children in the habit of brushing and taking care of their teeth is essential.

"Preventing cavities is the message I like to get out to children and parents," says Berg. 

He urges parents to discuss any concerns about their child's filling with the pediatric dentist.

    You could also make the argument that kids with more fillings already had behavioral problems as their parents were probably not able to get them to brush their teeth that much, leading to dental problems. So, is it kids have behavioral problems due to the fillings, or kids need to have more fillings due to behavioral problems?

      That's the real question. Isn't it? Knowing my 10 year old step son, I'd say it has more to do with the children, who are already behavior problems, refusing to brush.

      The more fillings tie is telling. Should this also be construed as an indication that diet is a factor in anxiety/depression and social stresses? I appreciate the information on BPA but isn't this also tied to hormone mimicking in females that contributes to estrogen type body responses? I don't think I want to post the possible bodily changes that might be occurring that drive the social stresses, but I'll let someone with less discretion attempt that.

      I would agree, but the study is comparing just those who have metal filllings versus those with tooth colored (BPA) fillings. It is not comparing those with fillings to those without.
      Still, its a small sample size, and there could be other things (perhaps cost difference hiding socioeconomic factors).

      But Gary and others who are saying it's likely that children who have behavioral problems don't brush: as others are saying, that explanation makes no sense whatsoever given the findings. The findings aren't saying that children with BPA fillings are more likely than children without fillings to have the behavioral issues. It's saying that children with BPA fillings are more likely than children who have METAL FILLINGS to have behavioral problems. The children with metal fillings are just as likely not to brush as are children with BPA fillings, so your explanation doesn't make any sense.

      So we stopped using amalgam fillings because of the fear of mercury. Now we're to stop using its replacement because of the fear of BPA. What are dentists to use? There are exposure limits for both and the dose in a filling of either is so small that it's doubtful that it is the cause of behavior problems. As the article points out, there's no cause and effect.

      Very good point. Another one to bring up is there is a distinct difference in income level between kids with composite vs. amalgam restorations. Composite is usually reserved for wealthier children since many insurance programs, including various assistance programs, do not cover the additional cost when compared to amalgam.

      This study only shows a possible correlation between composites (not BPA specifically) and behavioral issues, but there are several other environmental variables that have not been accounted for.

      You make a false assumtion that bad brushing = more fillings. My wife, daughter, and father in-law are prone to have cavities no matter how much care they give their teeth. If I were to let her my daughter would brush too much. My mother and myself have very strong teeth and not prone to cavities. I myself only have cavities because of my braces I had as a kid were the glue wore my teeth away.

      That line of questioning goes nowhere. Tooth decay is caused by bacteria that kids are not born with. They get exposed to it from their mothers (moms licking a finger for the baby to chew, per-chewing food for baby, or sharing food) or other family members or play buddies. There is also a genetic component at play (some parents carry genes for good teeth, some bad), the environment (water the child drinks while growing...not only fluoridation or none, but the amount of calcium in the water) and the dietary habits of the family (did Mom put the baby down with a bottle of fruit juice, was the child given candy and cookies regularly, did the child drink soda and fruit juice often). Regular brushing helps stave off decay, but these other factors play as big a role, or even bigger, on determining the state of a child's teeth.

      I'd like to know the effect on adults, as I had my amalgam fillings replaced with these white fillings way before 2005.

      Again, all of the people who are agreeing with the initial point are ignoring (or failed to read) the fact that the study showed a difference between BPA vs. metal fillings. Nutritional habits, lack of brushing are no explanation whatsoever for why BPA fillings are associated with more behavioral problems than are metal fillings. Are you going to try to argue that those who had metal fillings have better nutrition and brush their teeth more than those who had BPA fillings? There are plenty of alternative explanations that need to be ruled out, but differences in nutrition and tooth brushing clearly can't be one of them.

      There is an interesting thing that obviously flew under CNN:s radar.

      On July 2 Neurotoxicology and Teratology published a big investigation on strong effects from mercury fillings in boys with the genetic variant CPOX4 (approx. 25% of the population), Woods JS, et al, Modification of neurobehavioral effects of mercury by a genetic polymorphismof coproporphyrinogen
      oxidase in children, Neurotoxicol Teratol (2012), doi:10.1016/j.ntt.2012.06.004. See PubMed http://www.ncbi.nlm.nih.gov/pubmed/

      Why has this investigation recieved no media coverage at all? Is it to complicated and on a scientific level that few people are comfortable with? It will have a profound impact on the mercury fillings issue and on future safe limits for mercury as well.

      ““These findings have important public health implications,...”
      “...strongly associated with diminished performance across a wide range of the same
      tests, among boys with the CPOX4 variant.”
      “In conclusion, the present studies demonstrate significant adverse effects on
      neurobehavioral functions associated with chronic Hg exposure and the CPOX4 genetic variant
      among children, with effects manifested predominantly among boys. These findings are the first
      to describe a genetic polymorphism that modifies the effects of Hg exposure on neurobehavioral
      functions in children, and suggest directions for future research to define mechanisms underlying
      differential sensitivity to mercury between boys and girls”.

      As a DENTIST in Kentucky, I can tell you that the better behaved a child is, the more likely they are to brush twice a day and for two minutes at a time. Our "bad child" patients always have the worst teeth and the most fillings. Can't wait for all the anti-vacine moms to start coming in asking for us to NOT do filings for their kids.

So unless you're trying to say that the children with BPA fillings are less likely to brush their teeth than are children with metal fillings, using pre-existing behavioral problems as an explanation for the findings makes no logical sense whatsoever.

      No, there was *never* a sound scientific basis for linking vaccines to autism. The one "doctor" who allegedly found such a link admitted to falsifying his data. Jenny McCarthy remains an idiot who is responsible for a lot of kids getting sick that didn't have to.

      In this case we're talking about a chemical with known detrimental effects, but it remains to be seen whether its presence in dental fillings is actually cause for concern. The researchers themselves point that out.

    As a physician, I will say this is another worthless medical article. So often the media like to report a story simply because it is sensational and catches the attention of lay people. No one in the media seems to ask if this is even a valid trial. The fact that it is not randomized or that the study has obvious flaws such as not measuiring the BPA levels in the study subjects should disqualify this from even being mentioned in the media. Where is the sense of responsibility from these journalist who instead of helping communities create more confusion by misinforming the public. Unfortunately I see this all the time.

      That sigh keeps more distance between you and your patient. Maybe when patients are provided with teams of medical providers rather than one weary all-knowing doctor, their concerns will be addressed. Until then, educate them. Didn't you read that worthless study that says that patients are less likely to engage in unhealthy behaviors if their doctor advises them not to engage in that behavior? You don't need to walk them through the logic and reasoning or give a lesson on stats, but this could be their only opportunity to hear solid medical information in months, give it to them.

    So the question remains is that what are dental professionals supposed to do? They can't use metal fillings anymore because one group says it causes problems ranging from autism to MS. And, now they can't use composite resin because it may cause behavioral issues. I guess maybe parents should take better care of their children so that they don't have to undergo any dental treatment. Maybe that is the best solution to the situation.
    Also, please take into account that they is a casual association between obesity and lots of health problems. I don't see anyone pulling Big Macs and KFC off the market.

      Most children's fillings these days are non-amalgam so that is where I question the accuracy of the study. How about teens, adults? Very fishy study. Probably will be discounted by another study withing a few years, just like cell phone studies, dental x-rays, etc. Then of course it will be reinstated as vaild. This is a study that will act like a see-saw for years.

      Oh, I'm not claiming that the causality is definite without a whole lot of room for alternative explanations–I'm just saying that those particular alternative explanations aren't valid ones given how the study was done. But there's a lot more research to be done, and as is the case with a lot of field research, a slew of uncontrolled variables.

      One of the big ones is, as you point out, the fact that the majority of BPA fillings are new, whereas the majority of metal fillings were older. So a big question is (one that I can't answer because I'm not in the field of dentistry): besides the contents of fillings, what else has changed in dentistry during that time period (between when the majority of fillings were BPA vs. when they were metal)? I.e., a person with a lot of fillings has been to the dentist often and therefore had relatively frequent exposure to whatever else is happening during those procedures or other procedures that someone with a lot of dental work is more likely to have (e.g., topical anesthesia, how other procedures such as root canals that are relatively common for someone with a lot of tooth decay are done, types of xrays used, etc.). As new techniques and materials become available, things in dentistry change all the time. So are there other things that have changed in dentistry during that elapsed time period (between when metal vs. BPA fillings were common) that are actually causing the observed effect, while the difference in BPA vs. metal is just an artifactual difference (i.e., something that coincidentally changed during the same time period when the true causal factor also changed)? That's just pointing out the sort of problems that can occur when trying to infer causality in a study where the two things being measured occurred during very different time periods.

    Maybe the BPA is part of the behavioral problem but my guess it has a lot more to do with poverty then cavities. I am all in favor for kids brushing their teeth and going to the dentists but you have to have money to go to the dentists and buy tooth brushes and toothpaste. I know from personal experience that going to the dentist and even buying tooth brushes/toothpaste falls low on the list compared to buying food.

    Kids who have cavities are typically poorer. Blaming their behavior on their cavities and fillings instead of their poverty shows how Americans want to shift the blame for their problems on something other than poverty. If the fillings are causing the problem, then the parents are terrible because the kids are not brushing their teeth. If the kids behavior problems are caused by poverty then only being born to parents with money will fix the problem.

    Some will say that kids on welfare can go to the dentist but just try finding a dentist that takes welfare patients. So all of you Republican Christians step forward and urge that the government provide decent dental care for poor people. I will not hold my breath waiting for that to happen.

      i am a dentist that provides care to welfare patients. providing "decent dental care" is not the issue (at least where i live), and i do not believe it is the government's responsibility. and no i am not republican. the problem is motivation and education. i work in a state that provides nearly comprehensive dental care for people under the poverty level and it is more often times these patients that take for granted what they have...

      we see more people from that sector that...
      1) consistently do not show up for free care
      2) have a higher incidence of complications (dry socket, infection) due to infrequent or inconsistent care
      3) demand narcotics, or have narcotic addictions
      4) ignore reasonably simple advice (here is a toothbrush and toothpaste, i'm asking for you to take 5 minutes of your day)
      5) disrespect myself or my staff

      now we also have some great patients on welfare as well, BUT there's a higher likelihood of headaches.

      the biggest step forward is spending money on health education programs, in my opinion anyway.

The study ii NOT saying that kids with BPA fillings are more prone to behavior problems than are kids WITHOUT fillings–it's saying that kids with BPA fillings are more prone to behavior problems than are kids with METAL fillings. So the poverty explanation makes no sense whatsoever, unless you're trying to tell me that kids coming from impoverished families are more likely to have BPA fillings (as opposed to metal fillings) than are kids who come from non-impoverished families.

    CNN is the garbage can of of accurate and quality journalism. Not disputing the study, just CNN hyperbole. I would rather take the scientist who came to these conclusions to lunch and pick their brain on the study. I think you would get totally different perspective than what you get here.

      But Nan, that's true of all the media outlets at this point. Why single out CNN?

    Really folks, BPA is found in all kinds of food, leached from the plastic packaging it comes in. There's a lot being done to ban it, but it's just one of dozens of harmful chemicals that wind up in the food chain.. Just check the packages. I would guess that there is FAR more BPA leached into food from packaging than from tiny fillings. This logic falls into the category of, "There are far more drownings in summer. There are far more ice cream cones consumed in summer. Obviously ice cream cones cause drownings." Combine that with behavioral problems kids already have and I don't really see how these scientists in all honesty can draw the conclusion they've drawn. A lot more research has to be done. And with the new fillings, we've gotten rid of fillings that contained mercury as part of their matrix. Now THAT'S an element that WILL cause damage.

      Two points: the habits leading to the dental problems can be ruled out as a factor if those habits were the same for those with BPA fillings as they were for those with metal fillings. Remember, the study showed that BPA fillings were associated with more behavioral problems than were metal fillings.

      Point number 2: true, there maybe less BPA in a metal filling than in some of the other things we're exposed to, but remember that the metal filling is in your mouth exposing you to the BPAs 24 hours a day for as many years as you have the filling. That's no small thing.

      I'm not saying that there aren't a ton of alternative explanations to be ruled out, especially because as you pointed out, BPA fillings are common now whereas metal fillings used to be more common. So the kids with metal fillings had their fillings put in a while ago, while the kids with BPA fillings had them put in more recently. So an important question is: what other changes in dental procedures have occurred during that time that might have accounted for the difference? It might have been one of those other differences that caused the increase in behavior problems in kids with fillings, with metal vs. BPA just being something else that coincidentally changed during the same time period (without being the causal factor).

    the old fillings contained mercury (can you believe it, in your mouth) are you suggesting that we return to mercury?

    So having a lot of recent dental fillings is correlated with behavioral problems in children? I'd have behavioral problems too if I had to keep getting teeth drilled, and I'm an adult! Seriously though, more research needs to be done to prove BPA/behavioral causality. With all the chemicals in our environment, who knows? Just one more toxin...

    For those saying that the finding can be explained by pre-existing behavioral problems (e.g., kids with behavior issues are less likely to brush their teeth or more likely to eat garbage) or that eating lots of sugar is causing both the behavior problems and lots of cavities, please read the article more closely.

    The problem with either of these alternative explanations is ruled out by the fact that the study showed that kids with BPA fillings are more likely to have the behavioral problems than are kids with metal fillings. There's no reason to believe that the nutritional habits or pre-existing behavioral health of kids with metal fillings are any better or worse than the nutritional habits of kids with BPA fillings.

    I'm not saying that there aren't other alternative explanations that need to be ruled out, but those are two we can rule out right off the bat.

    If you eat anything out of a can the food probably has traces of BPA in it. Our envirnonment is so polluted I doubt you could ever pin it down to a single cause.

    you lot ought to give up first you stick mercury in peoples mouths and now toxic plastics. Composite or glass fillings would have to be the best option just because of the nature of glass and the way it is able to survive in the environment without degrading. Secondly id like to say that if dentistry and medicine werent so based around money and capitalist greed you would be doing your patients a far greater service. The primary focus of dentistry should be to prevent cavities from happening in the first place ,then if money was spent on research for a way to heal teeth naturally there would be no need to fill teeth. Dentistry needs to be rebuilt from the ground up and should be based around prevention first , natural healing of teeth second and if these options have not succeeded then filling the tooth should be the last option and it should be done with composite as the nature of glass is the best option. I realise what i have said will go in one ear and out the other as doctors and dentists chase the dollar signs but truly if there was one sector of socitey that should be of limits to money making it should be peoples health!!! I also believe dentistry should be scrapped and the role of tooth doctor should be given over to naturopathy as this profession understands that the health of a person mouth has a direct effect on there overall health and welll being.

    Your post contains excellent information about dental fillings which is very useful for me. Dental filling made from BPA, a controversial plastic chemical, have been linked to long term behavioral changes in children.

    As a responsible parent it is our obligation to educate our children about proper oral hygiene. Most kids as well as parents took dental hygiene for granted that is why numerous cases involving children with tooth problems arises. I know this because I am a goose creek dentist.

    As a mindful guardian its our commitment to instruct our squirts about genuine oral hygiene. Above all jokes and guardians underestimated dental hygiene that is why various cases including little people with tooth situations goes out. I know this resulting from the fact that I am an invisalign fairfield.

    The kids have always problem with their dental treatment or in fact any other treatment which they undergo, they create nuisance. I guess there should be some personal attention given to them by other people that time.

    My dentist edmond ok told me that dental fillings are just normal, but onece you felt a pain after 1 week, there must be a problem now. They should have checked the materials and the kid's condition before having the procedure.

    I hated the dental clinic in Calgary. But it is good for the kids. If my parents didn't make me do it then I would probably think that I had a lousy childhood. This blog raises some good points that people need to be aware of.
