Dental fillings are used to treat cavities. These cavities are caused by acid waste products from bacteria in your mouth that feed on sugars and starch. One of the primary ways your dentist can go about treating your cavity is by removing the decayed portions of it and then filling it up with material known as dental or tooth filling. But what types of fillings are available?

What are the types of dental fillings?

Having a cavity filled, which is a crucial area of your tooth decay, is a routine part of oral health care. When getting dental fillings, your dentist removes the affected portion of the tooth, leaving a hole or empty space. The space will then be filled to even out the tooth’s surface, making it “feel” right in the mouth and protecting it from further decay.

Silver amalgam fillings

This is the most common type of filling. Silver amalgam is a mixture of minerals that contains 50% silver, 50% tin, zinc, copper, and 50% mercury. It’s a popular filling material among dentists because it’s strong, durable, and inexpensive. A typical silver amalgam filling can last up to 12 years.

Composite dental fillings

Composite fillings are made of plastic material and resin that is soft when placed in the cavity and hardened with a curing light. It’s a popular choice because it can be color-matched to your natural teeth, making it less noticeable than a silver amalgam filling. Composite fillings should be replaced every five to ten years.

Glass fillings

These glass-and-acrylic fillings are ideal for children’s teeth that are still growing. They produce fluoride, which helps to protect teeth from further decay. However, they are significantly weaker than composite resin and are more likely to crack or wear out after a few years.
