What causes abscessed tooth?

ANSWER

An abscessed tooth is when a tooth’s root gets infected with bacteria and pus builds up around it. It usually happens if a cavity doesn’t get filled or a tooth is injured. Bacteria can get in through the cavity or a chip or crack in a tooth and spread to the root.

You’re more likely to have these kinds of issues if you don’t brush your teeth at least twice a day or there’s a lot of sugar in your diet. Sugary foods and drinks help bacteria grow, and that can lead to cavities and other problems.
