I am a 68 year old woman and had all my teeth extracted 17 days ago and had 8 implants with immediated dentures. I was told not to remove the dentures and, as a result of wearing them even in great pain, I have a large ulcer on my top gum which is bright red around the edge (about a half inch in diameter) which shows no sign of healing.  How long before it heals enough to continue wearing the relined denture?
Thanks for your query, I have gone through your query. The ulcer could be because of the trauma caused by the denture. Do not use the denture till the ulcer heals. It might take 5-7days for the ulcer to heal. You can apply topical anesthetic and analgesic like Anabel gel. If the ulcer does not heal in 10\u00a0days, consult an oral physician or planetologist to rule out the cause of ulceration. I hope my answer will help you, take care.
