Well I like the sound of this, seems there is a London dentist now using Laser instead of the dreaded drill in the preparation for filling teeth. No more drilling and no pain from injections. Wow! now that seems the way to go. It appears that the laser is capable of killing bacteria located deep in a cavity which leads to better long term restorations, so it works well if you have a very small amount of tooth left and need restorative crowns. It does have limitations as it cannot it seems, remove silver amalgam fillings and most of us over fifty have those. Still anything that helps with a trip to the dentist gets my seal of approval.
