An acute periodontal abscess (gum abscess) is an infection around a tooth usually caused by an acute flare up of existing gum disease. Periodontal means around the tooth and this means that the disease affects the supporting structures of the tooth - ie the gums, periodontal ligament (pdl) and alveolar bone. Acute means that the infection is in its ‘acute phase’ which refers to the types of response your immune system is making to the infection. Basically it means it is likely to be very painful and swollen this swelling may extend to the face or jaw and there can also be an associated fever.
