My dad is 91 with a bit of Dementia. He would like to have his last NINE teeth pulled from his lower jaw and get a lower denture. We talked to the oral surgeon and he doesn't see any teeth that could be salvaged for anchors. My understanding is that we remove all of his teeth, they implant at that time and then recover. The thought of a full denture depresses us as I have heard they are not very successful as actual functioning teeth. So we either try to salvage some of his original (they seem to be all rotten) or visit the implant option. Are the lower dentures successful?
