Teeth whitening is a bleaching process that lightens stains in the enamel and dentine of your teeth, to give a brighter tooth colour.
What are the benefits of teeth whitening?
Main benefit of teeth whitening is ‘the confidence of a bright white smile’. When you are going on job interview or a first date or making a big presentation or approaching a milestone and want to look your best. Whatever it may be, whitening is an easy way to boost your self-confidence. Knowing your smile looks its best makes you want to smile more and when you smile, the whole world tends to smile right back.
Are all teeth suitable for whitening?
Teeth whitening may be done on live teeth and teeth that have had root canal treatment. Before having your teeth whitened, our dentist will check to make sure your teeth are suitable to be treated.
In some cases, treatment may be difficult or ineffective, for example with staining caused during tooth formation by certain antibiotics. Tooth whitening may make your old fillings or crowns look darker after treatment, so it is very important to be checked and advised of this before you proceed. Areas of your teeth may whiten at different rates depending on the location of the stain, hardness of the tooth and the intensity of the stain.
How can your dentist whiten your teeth?
Tooth whitening can be done at home (using a customised tray system designed by your dentist), or in the dental office. Your dentist can provide a more effective tooth whitening system for use at home than the ‘do-it-yourself’ kits available at pharmacies. The dentist makes an impression for a model of your teeth. A thin, custom fitted, clear plastic tray that fits over your teeth is made. At home you place a whitening gel into the tray, and place the tray over your teeth. This is worn for 15 minutes up to two hours daily or at night. Results are usually seen after the first day, but maximum whitening may take 10-14 days. Your dentist will check on your progress.
Your dentist can also whiten your teeth at the dental office, using similar ingredients to the home use whitening. Your gums are protected and then whitening gel is applied to the teeth and may be activated with a special light for up to 30 to 60 minutes divided in 15minute sessions. Gel breaks down into stain-fighting radicals that break the molecular bonds making up stains on your teeth. The LED accelerator light shining on whitening gel helps these stain fighting radicals whiten faster. One big advantage of in-office whitening is you can see the result in just one visit.
