Dental and Oral Health (Children)

Only 6 teeth forming

07/21/2008

Question:

On the topic of Missing Adult Teeth- When a child has only 6 teeth forming and no genetic history of this anomaly is there any research on the occupations of the parents or the drugs being taken before or during the pregnancy that could be a possible source of the problem?

Answer:

There is good evidence that therapies for childhood cancer like radiation or the drugs used in chemotherapy can affect the development of teeth in children. We know of no occupational hazards or maternal drug use that would cause a child's teeth to be missing. The most common condition accompanying missing permanent teeth is ectodermal dysplasia and though genetically linked, it can occur without a previous history in the family.
