We have been With Advance laser dentist for several years. My wife had a beautiful smile with nice full mouth of teeth. Doctor notice that she had a over bite. After Watching it for years he noticed that the bottom teeth were pushing the upper teeth out which would weaken the bone and the gums. He recommended Invisalign which after several months has worked very well. She now has a even prettier smile and it makes her look younger. Thank you Dr. Vu Vo! And great staff.
