Insurance and Coverage

Denti-Cal: Confirmed Yes. Confirmed in the state's fee for service provider listing
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.
Safety net clinic: Yes. Clinics like this usually see patients with Medi-Cal, with other public coverage, and with no coverage at all on a sliding scale. Ask what they charge if you are uninsured.
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.

The Joo brothers make going to the dentist comfortable and relaxing. I had been going to a different practice that was bought out by an HMO-focused owner and the atmosphere changed from comfortable to uncomfortable, due to a revolving door of personnel. At Mosaic, you have James and Eric as your trustworthy dentists and I am confident you would feel the same.

I found this Dentist because of the reviews. From our first initial consultation/visit… to now my second this Dentist is amazing. I am extremely anxious when it comes to dentist visits but the staff here and especially the Dentist is extremely patient, kind, has a soft touch… and knows what he is doing. This doesn’t mean I don’t have my fear but this office is worth trying to overcome. 45 years of Dentist fear but I keep coming back for him to help me.
Pick this office you won’t be disappointed. There are not long waits and you get his full undivided attention. Thank you Mosaic!

Questions People Ask

Does Dr. Jason Joo take Denti-Cal?

Yes. This dentist appears in the state's published list of enrolled Denti-Cal providers. Taking the coverage and having an opening are two different things, so still call ahead.

How do I make an appointment?

Call (951) 460-1477 and say you have Medi-Cal dental. Or use the form on this page. Your request goes to the office if it takes requests here, and to our team if it does not. Nobody else gets it.

What will it cost me?

For most Denti-Cal covered treatment there is no copay. If the office suggests something the program does not cover, ask for the price in writing before you agree.
