My wisdom tooth is beginning to emerge and its hurting the area around it. and i have developed an ulcer. please help.

See a dentist: May be a localized infection with eruption. A dental evaluation is needed to see if this is happening. Probable eventual removal.

Extraction: Frequently wisdom teeth partially erupt, not coming all the way into place in the tooth line, so that can cause pain. Infection can occur when food gets trapped between a partially erupted wisdom tooth and the gum. Wisdom teeth that are painful are often infected. Removing these teeth can heal the ulcer and the pain.

See oral surgeon: See the oral surgeon for evaluation and treatment. Meantime, hot salt water soaks and gentle cleaning around the area. Get to the surgeon.

Check by Dentist: You should have it checked by your dentist or an oral surgeon. The tooth is likely partially impacted and will be a source for chronic problems since will be difficult to keep clean. The ulcer is likely due to the same.
