A dental abscess is the worsening of a dental cavity on the inside of the tooth pulp chamber. This area comprises the “meat” of your tooth. A dental abscess can also be the result of trauma to the tooth.
More common, however, is a dental abscess that starts with cavities. When a tooth has a dental cavity, it is open to bacteria and germs. If not filled in a timely manner by a dentist, a pocket of pus develops. Since infection is on the inside of the tooth, the pus has no place to drain, creating a dental abscess.
Look out for the warning signs: Toothache, red swollen gums, throbbing/gnawing pain, especially when chewing, swelling in the jaw or face, area is warm to the touch, foul taste in mouth, and bad breath.
The goal is to remove the infected pulp and any tooth decay. If this doesn’t work, a tooth extraction is the last resort. With a tooth extraction you might need a dental implants or a dental bridge so that the remaining teeth don’t shift. This makes a root canal infinitely more cost effective. Besides, keeping your natural teeth is nearly always the best course of action.
