Q. Recently had four inplants, prungs, on the front bottom. I am getting ulsers or sores on back side. How can I get rid of the ulsers to see if it the dentures I am wearing. You see, I had to wear my old dentures a week after the inplants. And could not take them out. The drilled holes in them to take the four prungs. I recently had new dentures. They told me try them for awhile. After the ulsers heal, we can see if the dentures work or fit. How can I get rid of these ulsers. I take them out at home so air hits the ulsers/ Rince my mouth out with warm salt water aand even rinced with peroxide… yuk Please advise. I had the dental work at aaffordable dentures.
