the small slit is in the gum. the burr will grind away dead jaw bone. don't worry, they are not a big deal. most ppl don't even have any pain after or very little. how adament are you on staying in frisco? i know dr david kennedy who trains in NICO for the IAOMT (he taught dr morales a few classes), and i can ask him if he knows a dentist in your area who does cavitations. it will probably be very expensive, but do you want me to ask him?
