I have used the Alviun Titanium Whitening Strips but now have white patches on my teeth. Why?

This white spotting is usually caused by dehydration and not an effect of Titanium White Formula. It may also be caused by the use of fluoride-based toothpaste as this blocks the absorption and action of the gel.

It will even out, you would just need to continue the course of whitening strips and the blotching will even out, and all the teeth will whiten as they should also stop the use of a fluoride-based paste for the course of the strips.

This can resume once the course is done. This does happen with some people and will even out in a couple of days with continued use of the strips.
