Can I brush my teeth after getting a cavity filled?

Generally, whether you can brush your teeth after filling a cavity depends on the curing status of the filling material. With resin materials, normal brushing is usually possible immediately after the procedure, while with glass ionomer materials, it is advisable to wait some time before brushing. The details are as follows:

If a light-cured resin material is used for the filling, the material will be hardened during the visit using a special curing light. Once cured, the tooth surface becomes stable, and normal brushing afterward will not affect the filling. In fact, brushing helps clean the mouth and prevent problems in other teeth.

When glass ionomer material is used, the curing process is relatively slow, requiring a certain amount of time to fully harden. Brushing immediately after the procedure may cause the material to dislodge or deform, compromising the filling's effectiveness. It is generally recommended to wait about 2 hours before brushing.

To protect the filled tooth and maintain overall oral health, use a soft-bristled toothbrush and gentle brushing motions to avoid excessive friction on the filled area. Rinse your mouth with warm water after meals to reduce food debris accumulation, and try to avoid very hard or sticky foods that could damage or dislodge the filling material.
