Dental abscess; Other names: Dentoalveolar abscess, Periapical abscess, tooth abscess, root abscess: A decayed, broken down tooth, which has undergone pulpal necrosis.A periapical abscess (i.e. around the apex of the tooth root) has then formed and pus is draining into the mouth via an intraoral sinus ().
Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The infection at the root of the tooth can travel through bone and infect surrounding soft tissue. Mouth infections are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. [1]
A periodontal abscess occurs alongside a tooth, and is different from the more common [2] periapical abscess, which represents the spread of infection from a dead tooth (i.e. which has undergone pulpal necrosis). To reflect this, sometimes the term "lateral (periodontal) abscess" is used.
Periapical periodontitis may develop into a periapical abscess, where a collection of pus forms at the end of the root, the consequence of spread of infection from the tooth pulp (odontogenic infection), or into a periapical cyst, where an epithelial lined, fluid-filled structure forms.
Advanced periodontitis: This is the most severe stage and a major cause of tooth loss in adults. In advanced periodontitis, you'll have deep gum pockets, significant bone loss, loose or shifting ...
A pericoronal abscess may occur during an acute episode of pericoronitis in the soft tissue surrounding the crown of a partially or fully erupted tooth, usually around a partially erupted and impacted mandibular third molar (lower wisdom tooth). Periodontal abscesses are the 3rd most common dental emergency, [13] occurring either as acute ...
The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots. The resulting pulpal necrosis causes proliferation of epithelial rests of Malassez which release toxins at the apex of the tooth. The body's inflammatory response will attack the source of the toxins, leading to ...
