Dental cysts are usually caused due to root infection involving tooth decay. Untreated dental caries then allow bacteria to reach the level of the pulp, causing infection. The bacteria gains access to the periapical region of the tooth through deeper infection of the pulp, traveling through the roots.
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.
An abscess originating from a tooth which has spread to involve the buccal space. Above, deformation of the cheek on the second day. Below, deformation on the third day. Sometimes the buccal space is reported to be the most commonly involved fascial space by dental abscesses, [2] although other sources report it is the submandibular space. [1]
Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.
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.
The most common location to find a mucocele is the inner surface of the lower lip. It can also be found on the inner side of the cheek (known as the buccal mucosa), on the anterior ventral tongue, and the floor of the mouth. When found on the floor of the mouth, the mucocele is referred to as a ranula. They are rarely found on the upper lip.
The most common and simple treatment is the construction of a specially made acrylic prosthesis that covers the biting surfaces of the teeth and protects the cheek, tongue, and labial mucosa (an occlusal splint). This is either employed in the short term as a habit-breaking intention or more permanently (e.g., wearing the prosthesis each night ...
It is a type of dental abscess. 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.
