Boone did a thorough cleaning as he always does. Dr. Nick did a quick examination with his explorer and did not find any areas of decay.
Laser cavity removal without numbing shots is a really exciting development. However, I wonder about a situation where a patient has a deep cavity. It seems that a laser is very effective for newer or superficial cavities where the stage of decay is not yet advanced. In the case of decay that progresses to being closer to the pulp, it does not seem like the laser would be as effective from a time standpoint. I had one of these deep cavities years ago and even with a drill, it took the dentist a long time to remove all of the bacteria. With a laser, removing such deep decay would take a lot longer. So for these situations, I would think that the traditional numbing injection and drill method would be preferred. Anyway, I think both techniques are valuable depending on the type of decay the patient has.
