hello malay*b, i'm so sorry for all the pain you've been going through.
Ironically, I've had the same problem with my teeth breaking off. I've never really anyone else here complain about it, last time it broke i had apple pie :? Maybe we should start a new thread about this.
About seeing u're doc, i think it best taking someone with for support, cos its a sad fact that some doctors do not take us seriously.
All the best and please let us know how things go
