Dental fillings are used to fill cavities and repair teeth that have been cracked or broken. This is most commonly done with materials called composite resin fillings that are designed to match the color of your teeth.
To fill a tooth, a local anesthetic is applied to numb the area and instruments are used to remove the decay and bacteria. In some cases, a liner is put in the tooth to protect the nerve. The filling is placed and then polished to make it feel smooth and natural. Often, if necessary, several fillings can be completed in one visit.
