Serving the Walnut Creek Community
We love being a part of the Walnut Creek community.

We understand the lifestyle of our Contra Costa County patients—busy, active, and health-conscious—and we have designed our office hours to accommodate your schedule.
Why should I visit a multi-specialty clinic like Mona Lisa Smile Dental?
By having an Oral Surgeon, Orthodontist, and Periodontist in the same Walnut Creek office, we ensure better communication between specialists and save you time driving to multiple locations.
Do you provide financing for dental implants or Invisalign?
Yes. We believe that quality care should be accessible. We offer a variety of payment plans and collaborate with most insurance companies to maximize your benefits.
How do I know whether I need a Periodontist or a General Dentist?
During your first Teeth Exam and Cleaning, our general dentists will evaluate your gum health. If they notice signs of advanced recession or bone loss, they will refer you to our Periodontist.
