Based on what my hygienist said about dentures last time I was in, I'm going with my grandmother's advice: Take care of your teeth, you don't want dentures".
What is the retirement coverage like? When I joined the company I worked at for 34 years, retirement medical was good. When I retired it was "here is a lump sum of accounting money that you can use ONLY to buy insurance through us" (self funded). Yeah, great deal. Needed the $28K/year coverage to not pay $33K a year just for DW's Enbrel. The pile was about gone when DW made full employee status at the Post Office which provides health and dental (minimal though it is) coverage for something over $8K a year.
