Q. Hi, I would like to have my teeth whitened. I have tried home kits from local chemists, however, I don’t find them particulalrlky easy to use, and they don’t have the desired effect. I am now considering visiting a dentistry for a one off treatment. I have been quoted £239 foa an hour session, which should give me between 5-10 shades lighter. The proceedure is described as the following…”cold light system activates the whitening solution that is applied to your teeth, making the whitening process fast and easy. After several minutes, the light shuts off, the whitening solution is taken off, fresh solution is applied, and the whitening light is turned on again. This may be repeated a few more times”. I am seeking independant advise regarding the treatment and whether it may compromise the long term health and colour of my teeth in anyway. I have been advised that the treatment should last for 2/3 years? I really dont want to pay more than the advertised price, would you recommend another treatment type? Thanks
