Wow, This guy is great. This is the first time in my 47 years of life that a dentist actually sat me down and TAUGHT me how to brush and floss correctly. Amazingly, all my previous dentist only told me I SHOULD brush and floss, but never SHOWED me how to actually do it. Dr.Chen is the first to teach me something that is assumed to be so known to everyone, but done wrong so often by almost everyone. Long story short, I've learned to control my periodontal disease and how to prevent it from getting worse: just by really good home care, really good brushing and flossing, and professional maintenance cleanings. My past mistakes has cost me a few teeth, but the good news is, I still have most of them and now I know how to keep them! Dr.Chen and his team of periodontist really cares and provides excellent care. The gum surgeries I had was virtually painless. I'm relieved that I finally took up the courage to go see a Periodontist. They have a great staff so I felt at ease the through the whole process from start to finish. I would highly recommend this office to anyone out there who needs to see a Periodontist.
