[|Human|] Hello,I have a reoccurring perfectly round crater-like sore on my gums that is incredibly painful. Its never in the same part of the gums twice and there is always a dimple right in the center of it. It starts off as a small round cut with yellowish liquid that comes out if pressure is applied on it and then it expands into the white, perfectly round spot. Its not near the base of my teeth on my gums. Ive had this three times so far in the course of 9 months and it is always just one singular sore every time. The ulcer usually lasts for about two weeks. I have also tested negative for HSV 1 and 2, with the last test being last month. I dont have braces, chew tobacco, or smoke. I also brush and floss regularly, use mouthwash, and have never had any teeth or gum problems before. I dont have any other symptoms besides the sore when it occurs. Ive had canker sores before, but they have never been on my gums and they never have liquid come out of them. My canker sores are also never perfectly round with a small hole-like dot right in the middle like these sores. What could this possibly be? What do I need to do? Thank you!
[|AI|]  Hello, Thanks for your query. Canker sores occur on the soft tissues in your mouth and on your gums and on and under the tongue. They are very painful. Before getting a canker sore, there is usually a burning or tingling sensation at the site. Then a round or oval-shaped red sore appears with a white or yellow center. Other symptoms can include swollen lymph nodes, fever and listlessness. See your physician if you have (a) the clustering kind of canker sores (b) pain that isn't helped by regular pain remedies (c) trouble eating and Chat Doctor. I do hope that you have found something helpful, and I will be glad to answer any further query. Take care
