A Holistic Approach for Lifelong Smiles

For Dr. Sien Siao and Dr. Dimple Rayani, dentistry is much more than a vocation – it’s their true passion! This passion inspires them to go above and beyond to deliver truly exceptional dental care every day that incorporates a “whole body” philosophy. If you’re looking for a compassionate and caring dentist in Brentwood, CA, you’ll notice the Balfour Dental difference from the moment you walk into our practice up to the completion of treatment. Our entire team is dedicated to helping you maintain healthy teeth for life—with maximum comfort and function, plus a beautiful smile, of course! We accent our advanced dental techniques with a good dose of pampering, including a hospitality drink bar, complimentary WiFi, headphones, cable TV and warm blankets.

Dr. Sien Siao

“ There are no words to express how wonderful I feel when I am able to give someone something they have been missing all their lives – a beautiful and healthy smile!”

Dr. Siao received his dental degree with honors from the University of the Pacific, Arthur A. Dugoni School of Dentistry. He founded Balfour Dental in 2004 with his dental partner and wife Dr. Dimple Rayani. To provide state-of-the-art aesthetic dentistry, Dr. Siao trained at the prestigious Las Vegas Institute of Advanced Dental Studies (LVI), completed dental implant courses and full arch training, and attained CEREC CAD-CAM certification.

Dr. Dimple Rayani

“For me, dentistry is about what I can do to help people. I’ve seen how the change in a person’s smile enhances his or her appearance and subsequently improves their life. I see it happen all the time and it never fails to amaze me – this is the ultimate measure of my success.”

Dr. Rayani received her dental degree with honors from Boston University’s Henry M. Goldman School of Dental Medicine, and completed the full core curriculum at the LVI. In line with her treatment philosophy of treating the whole patient, Dr. Rayani completed many LVI elective courses, including treatment of obstructive sleep apnea and TMJ. She also received advanced orthodontic training and is a preferred Invisalign provider.
