Purpose of a Filling
A filling is a way to restore a tooth damaged by decay back to its normal function and shape. If you have a tooth that has decay, or a cavity, it will require a filling. The dentist will remove the decayed tooth material, clean the affected area, and then fill the cleaned out cavity with a filling material. This filling material will help prevent further decay by closing off any cracks or spaces where bacteria could enter.
Types of Fillings
- Composite (tooth colored) fillings – These fillings are custom made to the exact color of your natural teeth, creating a more natural appearance.
- Gold fillings – These fillings are custom made in a laboratory and then cemented into place.
- Amalgam (silver) fillings – These fillings are the least expensive choice and are tolerant to wear. However, due to their dark color, they are more noticeable in the mouth and are not recommended for fillings in areas such as front teeth.
