Comprehensive Dental Care
in Orange, CA
General & Preventive Dentistry
Preventive care is the foundation of lasting oral health. Regular exams and professional cleanings help catch small concerns before they become larger problems, and our thorough approach means you always leave with a clear picture of where your smile stands.
Restorative Dentistry
When a tooth needs more than a cleaning, our restorative treatments — including dental crowns, bridges, implants, fillings, and root canal treatment — are designed to bring your smile back to full function with natural-looking, durable results.
Cosmetic Dentistry & Invisalign
From teeth whitening and porcelain veneers to Invisalign clear aligners, our cosmetic services are designed to help you feel confident in your smile. Dr. Sherry Darabi and Dr. Marilyn Nguyen, DDS are both experienced Invisalign providers, offering a discreet path to straighter teeth for teens and adults alike.
Emergency Dental Care
Dental emergencies don't wait for a convenient moment. If you are dealing with sudden tooth pain, a broken tooth, or another urgent concern, our team works to see you as quickly as possible. Learn more about our emergency dentist services and what to do if you need same-day care.
Insurance, Financing and In-House Membership Plans
Everyone deserves access to exceptional dental care. We accept most PPO insurance plans, offer flexible financing through CareCredit, Cherry, and Sunbit for patients who prefer to spread out the cost of treatment. We also provide affordable in-house membership plans for patients without dental insurance. Questions about your insurance? Our team is happy to verify your benefits before your appointment.
