To my knowledge there is no supplemental dental insurance when you retire. The dentist won't give you a break when your on a fixed income. FishHawk

President announcing new health plan today

Not sure it'll change your options tho.

FH, i talked to my dentist and was able to work out a plan with him as my wife has a lot of dental problems. I pay him $100/month wether i owe or not
so i don't get hit all at once.
It's worth a try if he is a reasonable guy.

I have seen supplemental dental plans but they don't cover much, basic check ups etc.
