Teeth whitening or bleaching is a cosmetic dental procedure that uses hydrogen peroxide to lighten the colour of the teeth. It can be done as in-office bleaching or at home, using bleaching trays made by the dentist.
The in-office bleaching method involves applying a protective cover to the gums, then a bleaching gel to the teeth and activating it with a cold / plasma light. This protective cover for the gums helps prevent teeth sensitivity.
The home bleaching method involves using bleaching trays custom-made by the dentist, which are filled with a bleaching gel, and worn for a specified period of time as prescribed by the dentist.
To maintain the whiteness of your teeth after bleaching, it’s important to avoid certain foods and drinks that can cause staining such as dark-coloured fruits and juices, coffee and tea, red wine, colas, beets, soy sauce, curry and dark chocolate to name a few.
To keep your teeth looking light in colour after bleaching, it is also important to brush and floss your teeth regularly to remove any food particles and stain-causing substances that may be stuck between the teeth. If you are not in the position to brush having had teeth-staining food or drink then rinse your mouth out with water. This is better than nothing if you can´t get to your toothbrush.
