Questions we get a lot

Are you accepting new patients?

Yes, at all five offices, and happily. Book online with whichever office you like, or call and the front desk will find you a time.

Do you take my insurance?

We accept most PPO plans and no HMO plans. Plans we work with include Aetna, Ameritas, BCBS, Cigna, Delta Dental, Guardian, Humana, MetLife and United Healthcare. Call your office before the visit and they will check your plan for you.

What if I don't have dental insurance?

You don't need insurance to see us. Each office has a membership plan that covers cleanings, exams and X-rays for a monthly fee, starting at $27 a month for adults. For bigger work, CareCredit lets you spread the cost over monthly payments.

Can I be seen today for a toothache or a broken tooth?

Call the office closest to you as early as you can. We see emergencies the same day during business hours whenever we can.

Which office should I choose?

Whichever one is closest. Lake Forest and Rancho Santa Margarita serve south Orange County, Yucaipa serves the Inland Empire, and La Quinta and Rancho Mirage serve the Coachella Valley. Our specialists see patients at several of the offices.
