Hello, i have a red hole in the back of my mouth. to clarify, its not in the tooth, but in the tissue. the surrounding area is very red and painful aswell. what exactly do i have?

If you have had any type of trauma to the area (a burn from hot food or impact with a sharp object) it could be caused by that type of thing, but more likely cause would be a viral infection causing an ulcer there (syphilis from oral sex Gould cause a chancre in the mouth but it is usually not painful) . Warm salt water gargles, lots of liquids, & Tylenol /ibuprofen can help. If worse see Dr

It's difficult to tell because we do not have the image. If you are not at risk for STD, I think you may have an aphthous ulcer or canker sore. This will hurt when you eat. You can put Orajel on it (teething gel for children) several times a day, especially before meal. The ulcer will heal by itself in a couple days. If you are at risk for STD, please see a doctor for help.

Size, onset, duration, depth, color, texture? May be ulcer (usually viral) or traumatic lesion. Treat symptoms: Take Ibuprofen (exactly as per pkg instructions), dab on Orabase-B w Q-tip, avoid hot and/or spicy foods. Should be completely gone in 2 weeks. If not, see your Dentist, a specialist Oral Pathologist, or a specialist Oral Surgeon.
