Teeth whitening can significantly improve the appearance of your smile for relatively little effort. That said, it's best to remember that less is more when it comes to whitening your teeth!
Brilliant, blindingly white teeth can look jarring, unnatural and just not very attractive. In fact, teeth that have been over-whitened can actually look quite weird in person.
That's why, 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. Making the mistake of over-whitening can have the opposite of the intended effect: it could make your smile less attractive.
Dental problems can also be caused by over-whitening your teeth. The whitening solution can soften your enamel, making your teeth feel extra sensitive. In extreme cases over-whitening may even cause your teeth to become a strange shade of blue-grey.
That said, it's important to note that teeth whitening is actually very safe, and it takes a lot of over-whitening to cause oral health problems.
Just remember to exercise caution when considering whitening your teeth.
