I have got the BriteSmile treatment in Elite Dental Group, Vietnam. The procedure was about 2 hours long but it was quick. It just took about 1h 30 minutes. It’s definitely pain-free. However, just need to avoid certain, I have no problems eating. I love my new teeth’s color now. I am so happy that I got this done at Elite. Dr. Hai takes care of me well and the staff are so friendly and helpful. Thank you!
