An interesting video on how laser can be used on the soft tissue in the mouth. The source of the video is from Biolase, the company that produce Waterlase. Personally, I have been using Waterlase mostly for gum contouring, gum depigmentation/gum whitening, frenum attachment removal and tongue tie release.

Hopefully, the video can provide some idea into what Laser Dentistry is able to achieve in the Dentistry.
