olivia4 - Tooth whitening can be a very effective way of lightening the natural colour of your teeth without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade.

crowdy - I am pretty sure it is. You see, I have been using it for a year already and should admit that it works pretty well for me. Plus I bought that unlimited zoom teeth whitening lamp https://bleach-infiniter.com/. You see, they offer a 30-day MONEY-BACK-GUARANTEE once you receive the product. You will have enough time to try our Bleach Infiniter.
