Got dentures but they insisted on giving me an upper pallet, blocking tongue from roof of mouth. I bought a Dremel Tool and used the plastic cutter with a little olive oil to cut out the center pallet. I used a Dremel sanding drum to smooth edges. I had no Dremel experience whatsoever but it was a breeze; no problems. I did have to rig a little jig, to hold the denture. So far works great with Fixodent Plus.
