More than half of American children have had a cavity by age 7. These days, more kids are getting fillings made of a tooth-colored composite instead of silver mercury fillings.
A chemical called BPA which has been linked to health concerns is sometimes used to make these composite fillings.
In a new study, published in the journal Pediatrics, researchers collected treatment data from more than 500 children seen at several community dental clinics.
The children were all 6 to 10 years old at the start of the 5-year trial.
Psychological assessments were made at the beginning and at completion.
The findings: Composite fillings that contained the material related to BPA were linked to anxiety, depression, social stress, and other problems. These issues weren't linked to mercury fillings, however.
The next time a cavity strikes your child, talk to your dentist about the benefits and possible concerns that may come with different types of fillings.
