Help! I have been to at least 10 different dentists (more if we go back a year or two) and none can seem to point me in the right direction. Missing teeth for an extended time caused my upper gum to meet lower teeth. No room in back for implants I’m told. 3 of the 10 dentists suggested full upper denture. I was ready to move ahead with this until one of the dentists said there is no room for that so she isn’t sure why they suggested that. All said not possible for partials.
