See an endodontist: Oral infections such as certain chronic abscess can often be difficult to diagnose and treat. In addition to dental school, endodontists receive 3 more years of advanced education in this kind of diagnosis and treatment. That’s why you should see an endodontist for proper diagnosis and treatment.
