I use Comfort Dental Gold Plan. I goto a Comfort Dental in Delaware, OH. There is also one in Marion, Springfield, and Whitehall. I did a decent amount of shopping around (quotes, etc, as I didn't have dental insurance) before settling on this place. They were literally thousands cheaper. Their Gold plan will save you a buttload and my personal dentist saves me a shitload on top of it by always cutting me discounts, etc.
Call up a Comfort Dental and ask for info or look it up yourself. Hope it helps. BTW, if you find something better, be sure to let us know here. Thanks.
