Can My Child Get a Cavity Under a Filling?

Cavities are a common dental issue in young patients. Dentists can treat this problem with dental fillings within one dental visit.

If the dental work becomes damaged, the patient may develop a cavity under the filling in what dental professionals refer to as recurrent tooth decay. Dr. Allie Miller, a pediatric dentist in Winter Park, FL, responds to frequently asked questions regarding recurrent decay in young patients.

What Is Recurrent Tooth Decay?

A cavity is a form of tooth decay in which the surface of the tooth, the enamel, deteriorates and forms a hole. A dentist treats the cavity by filling this hole with either silver or composite resin, creating a seal over the area to protect it from further damage.

However, if this dental filling wears down or falls out, the damaged part of the tooth becomes exposed. It may be at risk of developing another cavity in the area, which dentists call recurrent decay.

How Do Dentists Treat Recurrent Decay?

As with initial cavities, dentists must remove the damaged part of the tooth to treat the decay. They can provide a local anesthetic for optimal patient comfort during this procedure.

The dentist first removes the worn dental filling to access the surface of the tooth. Then they drill away the decay and provide the patient with another dental filling. In the event of severe decay, the dentist may give the patient a dental crown to shield the affected tooth.

Can I Prevent My Child from Developing Cavities Under Dental Fillings?

A vital way to prevent children from forming cavities is to practice good oral hygiene. This involves brushing teeth twice a day, flossing daily, and visiting the dentist for routine cleanings every six months.

To avoid recurrent decay, you should aim to preserve dental fillings. Fillings can wear down over time if exposed to abnormal amounts of pressure. This includes grinding teeth, clenching the jaw, or biting on hard items like ice or the end of a pen.
