Teeth whitening can significantly improve the appearance of your smile, as it makes a big difference for relatively little effort. However, when whitening your teeth, remember that less is more!
First of all, when you over-whitens their teeth, the result can be quite jarring. Brilliant, blindingly white teeth are not attractive, and can actually look quite weird in person.
Unless you have a career in television, or maybe modelling, it’s always better to err on the side of caution when it comes to teeth whitening, because over-doing it can have the opposite of the intended effect: it could make your smile less attractive.
Over-whitening your teeth can also lead to dental health problems. It can soften your enamel, making your teeth feel extra sensitive, and in extreme cases, it may even cause your teeth to become a strange, blue-grey colour.
nevertheless, teeth whitening is very safe, and it takes a lot of over-whiten your teeth to the extent that you wind up with oral health problems.
