I saw on here a few months ago that someone really recommended Crest WhiteStrips to whiten teeth (funny that). The thing is where is the cheapest place to get them from and what ones do I go for? There seem to be quite a few options!
Thanks
I got mine on ebay. about £25. I think they were Premium. Very good once you get used to them. Last quite a few months then you will need a top up so don't use the whole box unless you have to.
