Didn't want to start a new thread, but I had "laser whitening" this week, and it has made absolutely no difference whatsoever. Although I always take good care of my teeth, I've always felt they're a bit yellowish. I go to the dentist every six months to get a scale and polish with my check-up, and I also give my teeth a brush every couple of weeks with bicarbonate of soda and a mild solution of peroxide to remove any potential staining.
I did explain this to the girl carrying out the procedure, but she went ahead anyway, promising fabulous results. However, my teeth were not whitened at all.
She fobbed me off promising that it's an "oxidisation process" which takes a further 24hrs for full results, so I paid and left.
However, I'm really pi**ed off as I think they are basically passing off "whitening" as "stain removal".
