My HMO Dental insurance assigned me to this practice. I was told that I needed a deep root cleaning although I never had one in the past 71 years and I always had trusted my dentist. They also said a crown was cracked and needed to be replaced. In all the crowns I had this was one painful experience and it went on over 2 weeks. I questioned why they failed to originally submit the claims to the insurance company and they said it was not covered. Finally they submitted the paper work as they were required to but I am still out over $1, 000. I have gone to another dentist and confirmed that I never had any gum problems and the deep root cleaning was a rip-off in my opinion. My suggestion is be sure you are getting what you need.
