I had my teeth whitened about 3 years ago and would like to do it again but can't afford it. I was given the gel by the dentist and had the mould things made to fit my teeth so could do it at home.
I still have the things to go over my teeth but would like the gel. The ones in the chemist seem OK but I believe they aren't great as the level of bleach in over the counter products is minimal.
Anyone used one and how effective was it?
Thanks.
