If you have periodontal and/or other dental issues that your current dentist is on the brink of sending you to invasive/surgical procedures, you owe it to yourself to at least get a second opinion. I did with Dr. Tao, and count myself lucky that I did. Dr. Tao cares about the long-term well-being of her patients, and has the advanced skills and know-how to deliver the results. Now even routine cleaning feels like a breeze, compared to the previous bloody scraping torture sessions. Highly recommend.
