Chris,
Thank you for responding. It helps just to hear from someone else who can relate to my mom.
I figured there probably isn't anything I or anyone can do but encourage/support my mom through this. Her docs have emphasized that it will just take time & practice. I do think she has anxiety over it and maybe it would help if she could take medication to relieve that feeling. I just hope that she has a good experience tomorrow when she sees her prosthodontist.
In the meantime, I hope you have success with your definitive obturator. Thanks again for your input.
