Composite Fillings are required when the tooth structure has been destroyed by bacterial infection (also known as a cavity), or when an existing filling becomes defective. The defect of a filling might be caused by cracking or leaking of amalgam fillings, thus leading to new decay.
Other Reason for Composite Fillings:
- Chipped teeth.
- Closing space between two teeth.
- Cracked or broken teeth.
- Decayed teeth.
- Worn teeth.
Composite fillings can be placed in one visit, and are composed mainly of two primary ingredients: a binder of plastic resin and a filler of finely ground, glasslike particles that give them a lifelike appearance and durability. During this treatment, local anesthesia is administered and the decayed tooth structure is removed. The space left after the removal of the cavity is then replaced with an esthetic composite resin filling that functions in the same manner as the original tooth.
