About Our Practice

Our vision is to provide our patients with a dental experience that will promote a lifelong relationship built on trust, confidence, quality of work, and exceptional patient care.

Let us introduce ourselves! Sun Smile Dental Group has been making beautiful smiles in San Marcos, CA since 2005. We strive to build lifelong relationships with our patients. As our patient, we will meet with you to learn your dental history and to discuss your dental health and cosmetic goals. Education is one of the most significant cornerstones of our practice. We believe that patients should have sufficient information to make intelligent decisions about their oral health and treatment options. Our communication is the key to maintaining a beautiful, healthy smile that lasts a lifetime.

We welcome new patients of all ages, including both children and adults, to visit our comfortable, friendly dental office.
