Delta Dental (www.deltadentalins.com) or Aetna. That's the dental insurance I had. It all depends on which doctor you see. You need call them whether they accept your insurance or not before making an appointment. I used delta dental for deep clean and I paid about $250 and the insurance pay about $800-1000. But it depend on your teeth condition as well.
