Hi I had an ulcer on my gum underside and went to the dentist.  I ended up having to have root canal.  He put me on antibiotics and the ulcer seemed to have gone down.  It now seems to have flared up again and is slightly painful, could this just be an ulcer
Hi! Welcome to Chat Doctor. I read your query. Is the ulcer on same location as earlier? Does it appear like a boil or swelling at tooth root? I suggest visiting your dentist and get it checked. Get an x-ray done to know any infection in tooth. In that case it may need reject or extraction of tooth. Or it can be just abscess in gums due to some trauma or brushing injury. Or can be an ulcer. In case of gum abscess, you need a cleaning to while ulcer will heal with time. Maintain good oral hygiene. If warm water doe snot hurt, do warm saline rinses. If required, repeat antibiotic course after consulting dentist. Hope the answer helps you. Thank you.
