I had a friend who constantly used tooth whitening at home, and it was very effective . I also had a friend telling me those do it yourself whitening kits is painful on the teeth. But we girls go through much more pain to look beautiful. (I am one exception because I am scared of needles and low tolerance for pain). However, ever since my sister’s teeth started cracking, I became much more aware of the danger of tooth whitening. Even through my sister didn’t get her teeth weakened from whitening (the reason still unknown), dentists have said the whitening is abrasive and actually weakens your teeth, which leads to pain and even cracks. For that reason, I started paying more attention to my toothpaste. Those with “whitening” written on the box I would not even dare to use it again. The whitening kits contain chemicals such as baking soda, which can be dangerous in large quantities. Tooth whitening can also cause discolored spots on your teeth. These spots can appear in a number of different ways, but overall it simply looks like parts of your teeth have been whitened while other parts have not. Some parts of your teeth may respond at different rates to a tooth whitening procedure than others, which may leave you with an inconsistent finished product.
When it comes to beauty, I doubt even the most intelligent women can be convinced unless it threatens lives. But least now you know.
