[|Human|] I noticed about a month ago that my 8 yr old daughter had what looked like a small canker sore right above the front tooth on the left side. It was bothering her at the time and was red around the area. I didnt give it much thought at the time because I really thought it was just a canker sore. She has been to her orthodontist twice since I noticed it to get things started for her braces (she only has spacers at this time). The orthodontist didnt say anything about it at either visit. I noticed last night that it is still there. I decided I would feel it and it is hard and spiky feeling. It doesnt seem to bother her at all, but she acted like it hurt a little when I touched it. Do you have any idea what it might be?
[|AI|]  Hello, thank you for consulting with Chat Doctor. Canker sore does not stay for so long, it takes maximum 7-14 days to heal. The type of lesion you are mentioning, it can be a sinus opening, as it is present above the tooth in the gums. It is condition, which occur when a tooth is infected and there is an abscess formation in the apex of the tooth, and when the pus starts coming out it forms a sinus opening. You should visit your dentist and get an x-ray done of that tooth as it will show the infection. Hope it will help you.
