You can significantly improve the appearance of your smile by whitening your teeth. Whitening makes a big difference for relatively little effort. However, when you whiten your teeth, remember that less is more!
When teeth are over-whitened the result can be quite jarring. Brilliant, blindingly white teeth are not attractive or natural looking. They can actually look quite strange in person.
Unless you have a career in television, or possibly modelling, it’s always better to err on the side of caution when it comes to teeth whitening, since 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. It takes an excessive amount of whitening for your teeth to wind up with oral health problems.
