The Crest Whitening Strips are not licensed to be sold in the UK as they contain (i think) upto 6.5% Hydrogen Peroxide. I for one would not want that high a concentration of effective bleach in my mouth on a lose strip which will almost certainly cause irritation to my gums.
It is alot cheaper doing it this way as opposed to seeing your dentist but you wont have supervised whitening which is very important if you want a good result.
