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.
Putting pressure or warmth on the tooth may induce extreme pain. The area may be sensitive to touch and possibly swollen as well. This swelling may be present at either the base of the tooth, the gum, and/or the cheek, and sometimes can be reduced by applying ice packs. An acute abscess may be painless but still have a swelling present on the gum.
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
Periodontal abscesses may be difficult to distinguish from periapical abscesses. Since the management of a periodontal abscess is different from a periapical abscess, this differentiation is important to make (see Dental abscess#Diagnostic approach) For example, root canal therapy is unnecessary and has no impact on pain in a periodontal abscess.
Root canal treatment (blue arrows) carried out on the lower right first molar with temporary restoration in place Incision of an abscess above a front tooth and insertion of a surgical drain Odontogenic infection involving the buccal space. Above, deformation of the cheek on the second day.
A phoenix abscess is an acute exacerbation of a chronic periapical lesion. It is a dental abscess that can occur immediately following root canal treatment . Another cause is due to untreated necrotic pulp (chronic apical periodontitis). [ 1 ]
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]
Odontogenic infection starts as localised infection and may remain localised to the region where it started, or spread into adjacent or distant areas. It is estimated that 90–95% of all orofacial infections originate from the teeth or their supporting structures and are the most common infections in the oral and maxilofacial region. [3]
