Pericoronitis is a dental disorder wherein the gum tissues around the molar tooth become infected and swollen. This problem occurs when wisdom teeth is only partially erupt. This partial breakthrough of gum leaves opening for bacteria and causes infection. The possible causes of pericoronitis are poor hygiene and mechanical trauma on molar tissues that can cause inflammation.
When plaque or the bacterial layer (that remains on teeth after brushing) gets into flap of gums around teeth, it irritates the gums and leads to pericoronitis. In the severe stages of pericoronitis, swelling and infection extends beyond the jaw and also effect neck and cheeks.
In its early stage pericoronitis is very similar to normal teething. The main symptoms of acute phase of pericoronitis include:
When the infection gets spread in sublingual and para- pharyngeal spaces then Dysphagia occurs. The person has difficulty in swelling food.
In the sub-acute phase of the systematic symptoms of pericoronitis become less acute.
Systemic features completely vanish till the chronic stage of pericoronitis, except for the state of severe exacerbation. In chronic phase of pericoronitis, patient report dull pain and bad taste in oral cavities.
When intraoral periapical radiographs one can easily identify bony defect around the third molar.
If you report pain or swelling in near your wisdom tooth then your dentist will first physically examine the area. If there is any partially erupted teeth or presence of a gum flap then you dentist will advise for an X-ray. This is done to determine the alignment of the wisdom teeth and the treatment is given accordingly.
