When Are Fillings Needed?
Fillings are used to repair teeth that have been damaged. Fillings can be made from different materials, such as porcelain or silver amalgam, which are very common in dentistry. In fact, the American Dental Association estimates that 92% of adults between 20 and 64 years old have had cavities filled with fillings. There are several reasons why a person might need a filling, including:
Cavities
A cavity is a hole in your tooth. Cavities can occur naturally through wear or tear over time, but they’re also caused by eating foods that are high in sugars, calories, and acids.
The symptoms of a cavity include:
Tooth sensitivity to hot or cold temperatures
Tooth pain when biting down on something hard (like an apple)
Cracked tooth edges from biting on them too hard
