Teeth whitening is a procedure that can lighten the shade of your teeth and remove staining or discoloration caused by ageing, medications, or diet and lifestyle factors such as drinking coffee, tea, wine, or using tobacco products. Teeth whitening will not last forever, so the procedure will have to be repeated on a regular basis to maintain the desired colouration.
Teeth whitening can be done at home or in the dental office. Our dentists will often take a photo of your existing tooth colour to monitor your progress and compare the new lighter shade of your teeth throughout treatment.
In-office treatment involves the application of a light-activated whitening gel; this procedure is a quick and convenient way to achieve a smile you’ll love to show off. In-office whitening often takes between 30 to 90 minutes to complete and you will be able to see results immediately.
For in-home whitening, our dentists will take an impression of your teeth and then make custom mouthpieces (trays) to fit your teeth. The dentist will give you a supply of bleaching gel (usually containing hydrogen peroxide) that is applied to the tray and then you will be instructed to wear the tray for a certain amount of time. Care should be taken to use only the prescribed amount of whitening gel as any excess of the product can contact your gums and cause irritation. At home professional tray whitening generally takes 10 to 14 days, although you may notice results in as little as three to five days.
Both in-home and in-office teeth-whitening procedures can cause increased teeth sensitivity in some people. This is a normal side effect and usually subsides a few days after the whitening treatments have been completed. Whitening procedures should be avoided if you are pregnant.
