Teeth whitening is a great way to improve the appearance of your smile for relatively little effort. However, if you're thinking about whitening your teeth remember that less is more!
Brilliant, blindingly white teeth are not attractive, and can actually look quite weird in person. When someone over-whitens their teeth, the end result can be quite jarring.
It’s always better to err on the side of caution when it comes to whitening since over-doing it can have the opposite of the intended effect: it could make your smile less attractive.
Not only that, over-whitening your teeth can also lead to dental health problems. Over use of the whitening solution 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.
That being said, teeth whitening is very safe and it actually takes a lot of over-whitening to get to the point where you wind up with oral health problems.
