The increased use of antidepressants by children is causing concern among some dental professionals who are noticing an increase in cavities and infections in certain children.

Children using antidepressants are at an increased risk of developing cavities and oral infections because antidepressants cause dry mouth, reducing the body’s ability to secrete saliva, a natural bacteria destroyer. Saliva limits the growth of tooth decay bacteria and infections by coating teeth with protective minerals. Saliva is needed to clean the smooth surfaces of teeth and to remineralize them.

The dry-mouth side effect of antidepressants is a significant health problem and can go unrecognized by physicians and dentists.

Parents should consult the family dentist or physician if they notice the following symptoms: need to moisten mouth often, dry mouth when going to bed, less saliva present than before, difficulty swallowing and trouble eating dry foods.

"Parents, if your child is taking antidepressants, take some preventive steps," says Robert Dennison, DMD, Chairperson, Dental Policy, Delta Dental Plans Association. "Make sure your child brushes his or her teeth after every meal, flosses regularly, avoids sticky foods, and has his or her teeth cleaned at least twice a year. Your child should also drink plenty of water while eating, avoid drinks with caffeine, chew only sugarless gum, avoid spicy and acidic foods and eat fruits and vegetables with high water content.
