Went yesterday It's a lengthy procedure about 1.5 hours. The guy Martin is very nice and explains the procedure well. He took care preparing my gums to ensure none of the stuff got onto them as he explained it would burn like mad. He also mentioned zingers pain I might experience. I sat for 3 x 10 minutes sessions my mouth agape and being zapped! That said I literally could have fallen asleep during the process :)
no pains or burning. I'd been told not to expect miracles as I'd previously been a smoker and drink black tea and coffee. When I looked I got a shock WHITE teeth! Not perfect but a huge difference and to be honest probably looks more natural for it! We started to drive home and the first zinger hit. It was painful there's no two ways about it. after a night on medication (neurofen) I'm sitting here 21 hours later with teeth feeling sensitive but good and WHITE!!! He has an offer on £80 - 24/02/13 - worth it??? YES definitely :)
