If the innermost flesh of the tooth is swollen and painful, it can be checked to see if it is caused by the eruption of a wisdom tooth. If a wisdom tooth is erupting and causing pericoronitis, oral anti-inflammatory medication such as cephalosporin or metronidazole tablets can be given. Alternatively, medications such as amoxicillin or roxithromycin can be used. Local rinsing can be performed, and you can ask your doctor to help you rinse and then topically apply iodoglycerin at the dentistry department. In addition, mouthwash is recommended in the mouth to avoid food embedded in the blind pocket in general. The swelling of the innermost flesh of the tooth may also be caused by the opposing teeth, such as the opposing teeth are more oblique or elongated, which may bite into the local flesh buds, causing ulcers or trauma and pain, and the opposing teeth need to be extracted or ground short to avoid the swelling of the flesh of the tooth. In addition, if the wisdom tooth is blocked, the blocked wisdom tooth should be extracted after the inflammation is eliminated to avoid the decay of the adjacent teeth.
