hay collins,

effect on teeth of flouride (which is not an acid):-
it reduces tooth decay. it enhances the degree and speed of 
remineralization and renders the remineralized enamel which is more 
resistent to subsequent attack .
long term excess of flouride causes flourosis.
lethal dose = 32- 64 mg F/kg body weight
antidote is large volume of milk and refer to hospital for gastric 

other acids ...
i dont know what acids come in the category OTHER acids ... but mainly acid
produced on the tooth surface by the action of bacteria on food causes
deminarization of teeth which results in high risk of tooth decay!

Thanking You

Dr. Shoaib
