Dental fillings are a common restorative dental procedure used to repair teeth that have been damaged by decay or trauma—and they play a crucial role in preserving the health and longevity of teeth, allowing you to maintain a healthy smile. Fillings are needed when a cavity—a small hole in the tooth caused by decay—has formed. If left untreated, cavities can grow larger and affect the deeper layers of the tooth, leading to pain, sensitivity, and potential infection. By filling the cavity and sealing off the affected area, fillings prevent further decay and protect the tooth from additional damage. They also help to restore the tooth’s appearance: we can color-match the filling material to blend seamlessly with the surrounding teeth.
