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.
For instance, the periodontal ligament can detect the pressure exerted when biting on something smaller than a grain of sand (10–30 μm). [13]: 48 When a tooth is intentionally stimulated, about 33% of people can correctly identify the tooth, and about 20% cannot narrow the stimulus location down to a group of three teeth.
The tissue overlying the tooth is called the operculum, and the disorder is called pericoronitis which means inflammation around the crown of the tooth. [5]: 141 Low grade chronic periodontitis commonly occurs on either the wisdom tooth or the second molar, causing less obvious symptoms such as bad breath and bleeding from the gums. The teeth ...
An odontoma, also known as an odontome, is a benign tumour [4] linked to tooth development. [5] Specifically, it is a dental hamartoma, meaning that it is composed of normal dental tissue that has grown in an irregular way. It includes both odontogenic hard and soft tissues. [1]
A less common cause is acid erosion, which is the loss of hard dental tissues due to acids e.g. related to gastroesophageal reflux disease, bulimia or excessive consumption of acidic foods and drinks. Repeated exposures to a low pH cause the mineral content of the teeth on the outer layer of enamel to dissolve therefore leaving the dentine ...
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 ...
The pulp of a tooth with irreversible pulpitis may not be left alone to heal. That is at least the general viewpoint of the dental profession, and not every dentist would agree that a dead tooth must be treated. No statistics are known but it is possible to have a trouble-free tooth after irreversible pulpitis, albeit a dead tooth.
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain.One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament."
