A filling is a material means of restoring the form and function of a tooth that’s been damaged by decay. When Dr. Jolene Dague at Dague Dental Solutions is preparing a tooth for a filling, she begins by removing the decayed tooth material from the cavity, cleans the area thoroughly and then fills the space with the filling material the patient has chosen. This stops the cavity from advancing and restores the structural integrity of the tooth. Placing the filling also seals the spaces where other bacteria might enter the tooth, which helps to prevent future decay.
Materials commonly used for fillings include amalgam (a metal alloy), composite resin and porcelain. All three substances work well, but there are differences between them.
