L.S.
Ok I use to work for a pediatric dentist before I had my kids.
My first part of advice to give you is-u said the dentist traumatizes u-which I am assuming u mean u dislike going there as so many do, but please do not let your children pick up on your fear-encourage them.
Second milk carries-are the same as cavities-a cavity is a cavity.
Is this their first visit and is it a pediatric dentist? Usually they use some sort of sedation-whether it be an oral liquid sedation in combination with laughing gas or just laughing gas alone which gives them a euphoric feeling and relaxes them-does not put them to sleep. And then they numb with an injection just like you or I would get, but they are so relaxed kids usually never know they got one and they do not call it shots there so they never know they got a shot.
As far as the caps go if it is the front teeth they usually use the silver caps with white facing to look like a real tooth.
Hope this helps and if u need any other answers feel free to ask. L. :)
