A tooth-colored filling restores a damaged area using a material selected to blend with your tooth. Composite resin is placed and shaped directly, helping rebuild a surface while preserving the tooth structure that can remain.

Composite fills a prepared area of a premolar and is shaped to restore the tooth surface.
The animation simplifies placement. The size of the repair and the strength of the remaining tooth help determine whether a filling is suitable.
Understanding your care
Start with the purpose of treatment, then explore what matters for your own care.
A filling can address a cavity or selected damage when enough suitable tooth structure remains. The size, location, and forces on the tooth influence whether it is appropriate.
Composite is chosen to harmonize with surrounding tooth color. Appearance is one consideration alongside strength, moisture control, tooth position, and the demands placed on the repair.
The final shape needs to work with neighboring and opposing teeth. Contacts, margins, and the bite are carefully checked as part of completing the restoration.
From questions to a plan
The details and sequence depend on your assessment and individual treatment plan.
The dentist examines the tooth and any relevant images, then explains suitable options. A larger or structurally weakened area may need a different kind of restoration.
Comfort measures and isolation are planned as needed. The tooth is prepared for the chosen repair while preserving the structure that can appropriately remain.
The composite is placed, shaped, and hardened according to the material. Its form follows the area being restored and the way the tooth functions.
The dentist checks the bite and finishes the surface. Follow-up is based on the tooth, the restoration, and your overall risk of future decay.
Before you decide
Fillings can wear, chip, stain, or develop decay at their edges over time. Temporary sensitivity can occur, and deeper damage may need additional treatment. A large filling is not always the best choice for a weakened tooth; an onlay, crown, or another material may be considered. Your dentist can explain why a particular option fits the findings.
The material can be selected to blend with the tooth, but color matching and appearance vary. The size, location, surrounding tooth color, and material all influence the result.
A filling replaces a localized area. If the remaining tooth is too weakened to support that repair, covering more of the tooth with an onlay or crown may be considered.
Yes. The tooth around a filling can develop decay, particularly at the edges. Cleaning, prevention, and review remain important even after the original damaged area has been restored.
