My teeth are terrible. Crooked, some missing due to decay and many others with cavities.  Thanks to a dentist from my childhood that did not believe in sedation, nevermind local anesthetics, I would rather lose all of my teeth and get dentures or implants before setting foot in a dental office again.  

Think about that very hard before thinking it is a good idea to operate on a child while it is still conscious and capable of sensing pain.  Having teeth drilled or scaled with all senses intact was torture.
