Where do you live? My dentist came from HK, of course he speaks Cantonese to me. His office is in San Bruno, on El Camino Real (San Francisco). I cleaned my teeth twice a year and took X-ray and mended teeth this year. I paid nothing. Maybe my insurance coverage is good. He explained to me clearly before he did something on me. If the location is OK, I will let you know his phone number and address.
