One of the best inventions in modern dentistry is the laser. The last time I had to have work done my dentist used one of those instead of a mechanical drill, it was really great. No novacaine, no pain, very fast. Quick composite filling and I was out of his office in perhaps 20 minutes for the whole visit. The only time he used a mechanical tool was when he was making sure the edges of the composite filling were perfectly flush.
