Children's Dental Fillings: How Long Does It Take to Fill a Cavity?

Cavities are a common dental issue for children. Proper treatment is vital to preventing further decay and discomfort. For mild to moderate cavities, dental fillings restore a tooth’s structure and function, allowing kids to bite, chew, and speak normally.

Parents often wonder how long the process takes and what their child can expect during the procedure. While every case is different, most cavity fillings are generally quick and straightforward, with minimal disruption to a child’s routine.

How Long Does a Filling Take?

The time needed to fill a cavity depends on factors like the size and location of the decay and the type of filling material used. In most cases, a single filling takes 30–60 minutes from start to finish. Small cavities require less time, while larger or multiple cavities may extend the procedure. If sedation is used for an anxious child, extra time may be needed for preparation and recovery.

What Happens During the Procedure?

The dentist starts by numbing the affected area with a local anesthetic to ensure a pain-free experience. Next, the decayed part of the tooth is removed, and the area is thoroughly cleaned. Once the tooth is prepped, filling material—often composite resin for a natural look—is applied in layers and hardened with a special light. To complete the procedure, the dentist smooths and polishes the filling to ensure a comfortable bite.

What Should Kids Expect After a Filling?

After the procedure, a child’s mouth may remain numb for a few hours. Parents should encourage them to avoid chewing on the treated side to prevent accidentally biting their tongue, lips, or inner cheek. Mild sensitivity to hot, cold, or pressure is also normal, though this should subside within a couple of days. If discomfort persists or the filling feels uneven, a quick visit to the dentist can resolve the issue.

Once this process is complete, maintaining good oral hygiene and regular dental checkups will help prevent future cavities and keep the filling in good condition.
