The £250 offer was the first bonus! After reading about Zoom! tooth whitening I was prepared for the results to be minimal as I had quite yellow teeth (not due to smoking, but probably tea etc. over the last 50 years). I was also worried about sensitivity. However I am really pleased. The staff explained everything clearly, the appointment was made quickly, the actual I hour process is much more comfortable than I thought, the results are better than I expected and I have a home whitening kit included in the price. Well worth it for me, a quick fix that I wanted. Thank you.
