SMILEBAR IS THE FIRST INVISALIGN-ONLY BOUTIQUE IN BOSTON. STRAIGHTER TEETH WITH 3D TECHNOLOGY. Invisalign is the clear and removable alternative to braces. Smilebar's latest in 3D technology, Invisalign Certified Elite Providers, faster appointments and a beautiful boutique are all designed to make you not only love your perfect new teeth, but love the experience as well. We launched Smilebar to provide a truly unique Invisalign experience. As patients ourselves, we felt there should be a better way to get perfect teeth than the tired old dentist office. So we built a beautiful Invisalign-only brand and boutique to change the way the world experiences Orthodontics.
