What usually happens

The sequence and number of visits depend on the individual case.

  1. Assess the tooth

    The dentist checks the extent of decay and explains whether a filling can restore it.

  2. Prepare the area

    The affected area is prepared for the chosen material.

  3. Place the restoration

    The filling is placed and shaped according to the material’s requirements.

  4. Check function

    The dentist checks the bite and explains follow-up care.

Options to discuss

Composite

Tooth-colored resin used for many restorations.

Amalgam or other materials

Each has specific benefits and limitations; discuss individual health considerations.

A larger restoration

More extensive damage may need an inlay, onlay or crown.

Benefits, limits & trade-offs

An intact amalgam filling generally should not be removed solely to prevent disease. Discuss symptoms or material concerns with your dentist.
