Q.
Hello, I recently had a Chlorine Dioxide tooth whitening treatment at BrightWhites. I’m really worried about the results. A few hours after the treatment, I noticed that my teeth had lost their lustre and had a chalky appearance. I called Brightwhites, they said that my teeth were just dehydrated, to drink lots of water and use the ‘remineralising’ product (Whitelasting Gel) they had given me. Admittedly, after using this product, my teeth do feel less rough and dry. Otherwise they feel dirty like I’ve just had a glass of Coke.

Six weeks later, there’s a slightly less chalky appearance, but I’m certain that my teeth are turning brown. To be honest, my teeth were naturally very white before I had the treatment, but I saw a special offer on Keynoir – being a moderate smoker I thought my teeth could be even whiter. I really didn’t need to have this done, and I’m sorry that I didn’t do some more research before sitting in that chair!

I’ve been reading some real horror stories about Chlorine Dioxide. Has there been permanent damage to my enamel? My teeth are definitely turning brown, so what should I do? Am I able to get them whitened back to their original colour? Please help.
