Hello..
My orthodontist and I have actually agreed upon a fixed amount of
money for the braces fee, which is inclusive of every procedures.
However, after pulling out 2 of my teeth (after 1.5 yrs), the
orthodontist insisted on crowning 2 canine as they are too small to
close the gap between my teeth. Therefore, an additional charge was
imposed for the crowning. I heard that it is unneccessary for a normal
tooth to have crown, and the tooth needs to be re-shape to a small
size, which sounds really scary to me. Thus, I'm quite reluctant to
have crowning as I feel that my 2 canines are normal. Please advise me
on the following.

My orthodontist always mentioned to close the gap of my front teeth
with by enlarging my canine teeth( which i thought it is doing some
filling to the tooth). However, I did not know this term actually
refers to crowning, until he suggested crowning today. (I does not
know what is it until today, and I heard the process is painful)

Is it necessary for a normal tooth to have crowning on it?

Is it ethical or a common practice for a orthodontist to recommend
crowning during my braces period? (I had this thinking, please correct
me if I'm wrong. An orthodontist can simply pull out more of my teeth
so that he can make more money from the crowning charges.)

Should there be additional charges for the crowning in the braces
period?

Thanks in advance
