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 ().
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.
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.
Noticeable signs include receding gums,making the teeth appear longer. Gums may bleed more, and there may be some bone loss. Moderate periodontitis: As the gum disease progresses, pockets get deeper.
In its early stage, called gingivitis, the gums become swollen and red and may bleed. [5] It is considered the main cause of tooth loss for adults worldwide. [7] [8] In its more serious form, called periodontitis, the gums can pull away from the tooth, bone can be lost, and the teeth may loosen or fall out. [5] Halitosis (bad breath) may also ...
A periodontal abscess can occur as the result of tooth fracture, food packing into a periodontal pocket (with poorly shaped fillings), calculus build-up, and lowered immune responses (such as in diabetes). Periodontal abscess can also occur after periodontal scaling, which causes the gums to tighten around the teeth and trap debris in the pocket.
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]
In the initial stage of the infection, the pulp chamber is partially necrosed for a period of time and if left untreated, the area of cell death expands until the entire pulp necroses. The most common clinical signs present in a tooth with a necrosed pulp would be a grey discoloration of the crown and/or periapical radiolucency. This altered ...
