Welcome to Alta Loma Dental Care
Dr. Sidney Lee, a proud Rancho Cucamonga resident, has been caring for the local community’s dental needs for many years. We are happy to welcome new patients, urgent dental problems, and every valued referral from your friends and family members.
We accept patients with every need
Alta Loma Dental Care is a preferred provider with most major insurance companies, and we offer discounts to senior citizens and those without insurance. Our goal is to provide every patient with the care they need.

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:
- 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.
- X-rays if needed. Digital X-rays are taken only when your history or the exam calls for them.
- A thorough exam. Dr. Lee checks your teeth, gums and bite and screens for oral cancer.
- 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.
- 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.
