Teeth Whitening FAQ
How does teeth whitening work?
Stains on teeth can be classified in one of two ways: extrinsic or intrinsic. Extrinsic stains appear on the surface of your teeth. Intrinsic stains live between the micro cracks in your enamel and deep within your dentin (the layer of your tooth underneath your enamel). Whitening toothpastes and mouth rinses may be able to remove some of the extrinsic stains on your teeth. But only teeth whitening agents can remove the stubborn extrinsic stains and the unsightly intrinsic stains that cause your teeth to look discoloured.
Working from the inside out, the active ingredients in the whitening gel penetrates your teeth to break down the discoloured molecules deep down in your teeth, removing stains and whitens your smile.
Is teeth whitening for everyone?
Teeth whitening is a safe, comfortable way to get a bright, white smile. Results and treatment time may vary depending on the level of staining and whiteness desired. Crowns, bridges, fillings, and veneers will not whiten. We recommend visiting us for a prewhitening consultation so that they can help you choose the professional option that best fits your needs.
How long do teeth whitening results last?
Teeth whitening results are very stable; leaving you with a stunning smile long after treatment is over. However, there are a few factors that can make teeth lose their lustre. Things like genetics, diet, age, some medications (like tetracycline), and certain habits (like smoking) may affect the length of your whitening results. Fortunately, touch-up treatments are quick and easy, helping you get that bright, white smile.
Will teeth whitening cause tooth sensitivity?
Tooth sensitivity is a relatively common side effect of teeth whitening. If sensitivity occurs, it is often temporary and will go away once you’ve completed the whitening process. Good quality whitening products include desensitizing ingredients like potassium nitrate and fluoride to help reduce sensitivity and provide additional comfort.
