Is Zoom tooth whitening for Coffee stains and tobacco stains
Hi I have bad stains on my teeth bcause of coffee and tobacco smoking and i was wondering if zoom teeth whitening is the best thing for this i have read that with the zoom it can make you teeth a lot whiter in 1 hour and a lot of places do zoom teeth whitening quiet cheap where i live, its strange how some clinics charge 250 quid and others charge 600 why such a big difference surely they both do the same thing and use the same tools?
