What is a dental abscess?
Your tooth may have had a big cavity. Bacteria in the cavity travels to the pulp of the tooth and infects the area around the root of the tooth.
This is when you start feeling pain. Sometimes you may develop a painful swelling either inside or outside your mouth.
When should you see your dentist?
Ideally, before you started having toothache! If you have already started feeling pain, see your dentist now.
Most abscesses are not life threatening. However, some of them could be life threatening. They are better treated the earliest possible.
