Hello MK

Are they extracting all your teeth? I have full removable lower dentures. On top I have 4 teeth that my removable partial dentures clip to. My MO who is also a dental surgeon, said my 4 teeth need to be extracted. My RO confirmed this. I asked if I should get an imprint before they pulled the teeth. He said no. That they would make a new set. I asked why not get them now, so they will be "waiting" for me, and be like my present ones. He said that my gums would shrink so much that taking imprints now is not required, and that they would make new dentures based on my gums, not my teeth. Are they only extracting some teeth on your right side?
