Dental fillings are used to repair cavities, which are small holes in the teeth that can be caused by tooth decay. Fillings are made of a variety of materials, including amalgam, composite resin, and glass ionomer.
Amalgam fillings are the most common type of filling. They are made of a mixture of silver, mercury, tin, and copper. Amalgam fillings are strong and durable, but they can be discolored and may not match the color of your natural teeth.
Composite resin fillings are made of a plastic resin that is bonded to the tooth. Composite resin fillings are tooth-colored and can be matched to the color of your natural teeth. They are also more resistant to staining than amalgam fillings.
Glass ionomer fillings are made of a glass-like material that is bonded to the tooth. Glass ionomer fillings are tooth-colored and can be matched to the color of your natural teeth. They are also fluoride-releasing, which can help to prevent further decay.
The type of filling that is right for you will depend on the size and location of the cavity, as well as your personal preferences.
Here are some of the benefits of dental fillings:
- They can repair cavities and prevent further decay.
- They can improve the appearance of your teeth.
- They are relatively inexpensive and easy to do.
