What Causes Canker Sore And Mouth Ulcers?

Hello, I think I may have a gum boil but I am not sure. I have been researching for a couple of hours. I looked at canker sores and mouth ulcers and it seems most like a gum boil. I have had this place on my top right gum for about a month. One day I tasted blood badley and it felt like maybe it was from that. I have accidently drained the pus out of the pocket. I was trying to see what it looks like and felt like just to figure it out. once i did that I tried to get all the pus out. Then it looked like a flat piece of skin that was hanging from the gum but very small in size. It has been about 20 minutes and it seems to be getting larger again, maybe with more pus, im not sure. I have never had anything on my gums or mouth before. However I have had a root canal before that I never got the crown for due to financial difficulty. My dentist referred me to a specialist about a year ago, but I have been unable to go, about 5 months ago the rest of my tooth that never got crowned came out it pretty much all broke off. I know I need to get this fixed but I havent been able to. But the tooth that had the root canal and then broke off is on the same side of my mouth but it on my bottom teeth. The pocket or place is above my right teeth at the very top of my gum. I am the type that washes my hands continually and now every time I touch my mouth. I am also afraid because I have two children that sometimes come behind me and drink after to me. I have told them not too especially now since there is something going on in my mouth. Can you please give your advice? I am so afraid of it being a canker sore or something or even this I dont know whats worse. Thank you

Hello,
You need the care and advice of a dentist to address this situation. X-rays are needed to address your current condition. Infections can make a pathway called a fistula to drain. This pus needs to escape. It can reoccur. This may appear as a gum boil when getting ready to burst. Other mouth sores can be viral in nature and not related to a tooth infection. An exam would be best to determine what condition you have.
Root canals treat infections, but if you delay restoring a tooth, you risk fracture. You now need to determine if the remaining tooth can be restored or needs an extraction. Once you complete the root canal, a tooth will often not be painful, but tooth structure can continue to decay. I am unsure which specialist was suggested to you. You seem to be discussing multiple teeth. Please schedule an exam with your dentist. I would be glad to answer addition questions and am available to assist you.
