You can get individual dental plans for less than 20 bucks a month if you stay in the network. My blue cross Medicare will reimburse a portion of my dental bill.
They don’t pay enough for anything other than minor stuff like cleaning etc and are capped at less than $1000 per year - most at $700
Wife and I are insured to death it seems like, and yet, almost nothing is covered. We both have Medicare, and Blue Cross supplemental, and dental, and eye. Basically all the dental and eye part does is allow you to make payments in advance on some procedures. We still have to pay for glasses, and the dental doesn’t pay for implants and other procedures. Neither Medicare or Blue Cross would cover the $7k for hearing aids, but if your hearing is bad enough, they will pay for cochlear implants.
