Insurance and Coverage

Denti-Cal: Not confirmed This office is listed as taking Denti-Cal but we could not find it in the current state listing. That is not the same as a no, so call and ask.
Medi-Cal plan type: Fee for service. Medi-Cal dental also runs through managed care plans in Sacramento and Los Angeles counties, and the state list we check does not cover those. If you are on a dental plan card rather than plain Medi-Cal, ask the office whether they take your plan.
Other insurance: Not known. This list is built around Medi-Cal dental, so it does not track private plans. Ask the office which ones they take.

What Patients Said

4.9

4.9 out of 5 from 166 reviews.

I have been a patient for at least 20 years. Dr Vainer and his staff are truly kind and genuine people. They are always so patient and gentle and have never made fun of the fact that I am extremely fearful of the dentist. Because of their gentle handling of me, I am now able to get my teeth cleaned regularly without the aid of nitrous or novocaine.

Dr Vanier is the absolute best and goes out of his way to make me comfortable and explaining what is needed in great detail. Everyone in his office is amazing and gives me a feeling of family. I am very nervous going to the dentist, but once I am there, I am very comfortable.
