We are here for you

Because we have been practicing in Rancho Cucamonga for so many years, we have had the pleasure of seeing our patients grow from childhood to adulthood – and then bring in their own children. If you are looking for a gentle family dentist – or need a trusted dental professional for your oral care, contact us here at Alta Loma Dental Care.

What to Expect at Your First Visit

Your first appointment is about getting to know you and your mouth, not rushing into treatment. Here is how it usually goes:

  1. Paperwork and history. Arrive a few minutes early with your photo ID, insurance card and a list of medications. We review your medical and dental history and anything that is bothering you.
  2. X-rays if needed. Digital X-rays are taken only when your history or the exam calls for them.
  3. A thorough exam. Dr. Lee checks your teeth, gums and bite and screens for oral cancer.
  4. Cleaning. If your gums are healthy, your cleaning is usually done the same visit. If there are signs of gum disease, we schedule the right type of cleaning so it is done properly.
  5. Findings and a plan. You get a plain-language explanation of what we found, your options, and a written estimate after we verify your insurance.

Plan on 60 to 90 minutes. You can read more about routine care on our exams and cleanings page.

Insurance and Payment Options

We accept most major PPO insurance plans (we don’t accept HMO or DHMO plans). Before treatment we verify your benefits, file claims for you and explain what your plan covers, so there are no surprise bills. Patients without insurance receive a discount, as do senior citizens, and our new-patient specials bundle a first exam and X-rays at a reduced price. For larger treatment plans we offer Cherry payment plans, with 0% APR options for eligible patients; ask our front desk for details. Our guide to affordable dental care in Rancho Cucamonga has more on keeping costs predictable.

Nervous About the Dentist?

You are not alone, and it does not change how we treat you. We go at your pace, explain each step before we do it, and agree on a signal so you can pause at any time. Mention your concerns when you book so we can plan extra time. Our guide to managing dental anxiety covers what to expect and simple techniques that help before and during a visit.

Bringing the Kids?

We see children alongside their parents and can often schedule family members back-to-back. See pediatric dental care for what a child’s first visits look like, and our family dentistry page for care at every age.

Questions

Questions for new patients

Something else on your mind? Call (909) 987-6268 and our front desk will help.

What should I bring to my first appointment?

Please bring a photo ID, your dental insurance card if you have one, and a list of any medications you take. Arriving a few minutes early gives you time to complete your paperwork comfortably.

What happens at a new-patient visit?

We review your medical and dental history and any concerns, take digital X-rays if they are needed, and Dr. Lee examines your teeth, gums and bite, including an oral cancer screening. If your gums are healthy you can usually have your cleaning the same day; otherwise we schedule the right type of cleaning separately. You leave with a clear explanation of the findings and a written estimate. Plan on about 60 to 90 minutes.

Do you accept my dental insurance?

Alta Loma Dental Care is a preferred provider with most major insurance companies. We also offer discounts to senior citizens and patients without insurance. Call (909) 987-6268 and we will verify your benefits before your visit.

Do you offer financing or payment plans?

We verify your insurance benefits and explain costs before treatment begins, and for larger treatment plans we offer payment plans through Cherry for eligible patients. Patients without insurance can ask about our new-patient specials and uninsured-patient discounts.

Do you offer new patient specials?

Yes — we run new-patient specials that bundle your first exam and X-rays at a reduced price. Call us at (909) 987-6268 to hear the current offers.

I have not seen a dentist in years. What should I expect?

No lectures. Many patients come back after a long gap because of fear, cost or a busy life, and we see it often. We start by listening, explain what we find, take care of anything urgent first, and go at your pace with the rest of the plan.

Can my whole family be seen at your office?

Absolutely. We are a family dental office serving Rancho Cucamonga — many of our patients first visited as kids and now bring in their own children. We can often coordinate appointments so family members are seen back-to-back.

Can I be seen the same day if I am in pain?

Call us during office hours (Mon–Fri, 9 AM–5 PM) and we will fit urgent cases in the same day whenever possible. For severe swelling, uncontrolled bleeding or facial trauma after hours, go to the nearest emergency room.
