My best friend just returned from an expensive tooth cleaning session using laser. That is a new one on me:
What Is Laser Dental Cleaning? (with pictures)
Side note: Back circa 1980, I was "attacked" in the hallway of one of the wings of my Community College by a horde of pretty girls in white uniforms. Turns out they were dental hygiene students recruiting patients for them to "practice" on. I "reluctantly" gave in to one of the girls (Andrea) who looked a little like a young Elizabeth Taylor. Since I was her "first" patient, it took three appointments to finish my mouth. By that time, I had fallen in love with her, asked her to a party, and we even dated for a couple of years.
