Dentists apply a sealant to a patient’s teeth to prevent decay. Molars, premolars and other teeth that have deep grooves can trap food and invite cavities. Sealants are a preventative measure since these teeth with deep grooves are challenging to keep clean.
Children and teens are the most likely to get sealants. Once a child’s permanent back teeth come in, your dentist might recommend sealants to protect these teeth throughout the cavity-prone ages of 6-16 as children learn to clean their teeth properly.
Another reason for a sealant is if a child’s baby teeth have deep grooves in them. This leaves your child prone to cavities, even with the best oral hygiene habits.
