A higher risk of tooth decay is observed in children who are exposed to second-hand smoke, researchers claim

According to Healthy People 2020, approximately 33 percent of children between the ages of three and five years old, and nearly 55 per cent of children ages six to nine, experienced cavities in at least one baby tooth from 1999 to 2004.
The study has been published in the Journal of the American Dental Association (JADA).
