Cavities occur when plaque, or bacteria, destroys the tooth enamel. As the enamel erodes, a hole in the tooth is formed. It’s important to remove the decay and fill in that hole as soon as possible to prevent further damage from happening. While we can’t get the original tooth enamel back, we can use the next best thing: fillings.
Fillings can be made from a few different materials, including metal (amalgam or gold) or white plastic, which is also called composite or resin. People tend to prefer these fillings because they have a natural-looking tooth color that won’t be noticeable. They’re also very durable to withstand chewing throughout the years because they bond the tooth together, rather than shoving a metal wedge into a hoe.
