I started to see Dr. H. Duong at the end of 2006 after I found someone recommend him on CFC. Since 2007, I did filling, cleaning and crown at his clinic and am really satisfied at his service. He is a good and "gentle" dentist that you normally do not feel pain while he is fixing your teeth. And his rate is reasonable (not like my previous dentist who just wants to make money). For people who do not have insurance, he also give discount. Usually, I can get an appointment within 1-2 weeks. Dr. H. Duong provides complete family dental care, includes: Emergencies; tooth whitening; teath cleaning; root canal therapy;cosmetic dentistry; minor surgery; crown & briddge; dentures... Good news: Since April 2010--Dr Dong's clinic has a 专业洗牙师. His address is: 1893 baseline rd (across from home depot, very close to College square shopping mall/Algoquin College). Office hours: Monday & Wednesday 9am-3pm; Tuesday & Thursday 12-8pm; Saturday 10am-4pm Phone number 613-723-3088 (you can call any time, even after office hour, to make appointment) He is a Chinese born in Vietnam. He can speak English, French, Vietnamese, and a little Cantonese.
