Who Is Dr. Sidney Lee?
Dr. Lee is a general dentist who provides preventive, restorative and cosmetic care for the whole family at one office.

Before coming to Rancho Cucamonga, Dr. Lee practiced in Monterey County, where he built broad experience in comprehensive dental services: preventive care, restorative treatments such as fillings and crowns, and cosmetic procedures. He provides that same range of care at Alta Loma Dental Care, from routine exams and cleanings to dental implants, and refers to a trusted specialist when a case calls for one.
How Dr. Lee Practices
- Listen first. Every visit starts with your concerns and history, not a treatment plan.
- Explain clearly. You hear what he found and your options in plain language before anything is scheduled.
- Comfort matters. Nervous patients set the pace; our guide to managing dental anxiety explains how a visit can be made easier.
