Pericoronitis is a common problem in young adults with partial tooth
Teeth are small, calcified, whitish structures found in the jaws of many vertebrates that are used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are embedded in the Mandible bone or the Maxillary bone and are...

Tooth impaction
Impacted and embedded teeth are the two main types of unerupted teeth found in the mouth, and can sometimes be confused with each other.In cases of both impacted and embedded teeth, the teeth remain below the surface of the gum and sometimes bone, rather than erupting into an exposed position...

s. It usually occurs within 17 to 24 years of age as it is when the third molars start erupting. It occurs when the tissue around the wisdom tooth has become inflamed because bacteria

 have invaded the area. Poor oral hygiene and mechanical trauma on nearby tissue can cause this inflammation. However, it can be impossible to effectively brush the necessary area and prevent this from occurring due to a partially erupted tooth. Chronic pericoronitis may be the etiology for the development of paradental cyst

Paradental cysts constitute a family of inflammatory odontogenic cyst, that typically appear in relation to crown or root of partially erupted molar tooth...

, an inflammatory
Inflammation is part of the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. Inflammation is a protective attempt by the organism to remove the injurious stimuli and to initiate the healing process...

Odontogenic cyst
Odontogenic cyst is a closed sac, having a distinct membrane derived from rests of odontogenic epithelium. It may contain air, fluids, or semi-solid material. Intra-bony cysts are most common in the jaws, because the mandible and maxilla are the only bones with epithelial components. That...

A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery.- Locations :* Acne...


Food impaction and caries
Caries is a progressive destruction of any kind of bone structure, including the skull, ribs and other bones, or the teeth. Caries can be caused by osteomyelitis, which is a microorganism disease. A disease that involves caries is mastoiditis, an inflammation of the mastoid process, in which the...

Treatment for minor symptoms of pericoronitis (spontaneous pain, localized swelling, purulence/drainage, foul taste) is irrigation. Major symptoms of pericoronitis (difficulty swallowing, enlarged lymph nodes, fever, limited mouth opening, facial cellulitis/infection) are usually treated with antibiotics. In most instances the symptoms will recur and the only definitive treatment is extraction. If left untreated, however, recurring infections are likely, and the infection can eventually spread to other areas of the mouth. The most severe cases are treated in a hospital and may require intravenous antibiotics and surgery.

The removal of the wisdom tooth
Wisdom tooth
A wisdom tooth, in humans, is any of the usually four third molars. Wisdom teeth usually appear between the ages of 17 and 25. Most adults have four wisdom teeth, but it is possible to have fewer , or more, in which case they are called supernumerary teeth...

 (extraction) should occur at a time when the acute phase or "infection" is not present, as extracting this tooth during the time of the acute/painful infection can cause the infection to spread to dangerous area around the throat. Therefore, a dentist will usually clean the area and/or prescribe antibiotics and wait for it to calm down until scheduling the extraction of it.

Pericoronitis can be managed with local debridement
Debridement is the medical removal of a patient's dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue...

and warm salt water rinses. It should go away in about one week. However, if the tooth does not completely enter the mouth and food and bacteria keep building up under the gum, pericoronitis will more than likely return.

Pericoronitis does not cause any long-term effects. If the affected tooth is removed or erupts fully into the mouth, the condition cannot return.
