If the inside of your tooth, where the nerve and pulp are, gets infected or decayed, a root canal might be the only way to save it. In a root canal, the dentist takes out the infected parts, like nerves, pulp, bacteria, and decay. Then, they clean up the space and fill it with special dental fillings.

Root canal treatments not only fix the tooth but also help prevent future pain and save on medical costs. Sometimes, pulling out a tooth can be more expensive and cause issues for the nearby teeth later on
