Hi Celtic
Yep so far nothing over the counter has worked for me either. I have good quality teeth, no holes or gum problems they are just burnt yellow from stomach acid. I have religously built up the enamel over the past few years but that didnt make them whiter : (
Laser treatment would cost about $1500 and UP! Ouch

PS Celtic - wow we are due almost the same time. Are you feeling like your carrying a hippo too? he-he.

Anyway, There must be something on the market that works..
Anyone?
