Dental Abscesses and Infection in Gums: What You Need to Know. You're relaxing after a day at work or spending time with your family when you feel a sharp pain in your mouth. If you have a history of dental problems â such as infection in gums, teeth or even cavities â the pain could be related to a dental abscess. There are two types of dental abscess: A periapical, or tooth abscess, affects the root of the tooth. The other type, a periodontal (gum) abscess, affects the gums.
