Below is a series of questions that we at WaveLight Advanced Teeth Whitening get asked all the time. If the answer to your question isn’t here, please contact us. We’d be thrilled to clarify anything about our products and services.

Q. Is teeth whitening safe?

A. Yes. Extensive research and clinical studies indicate that whitening teeth is safe. In fact, many dentists consider teeth whitening the safest cosmetic dental procedure available. However, there are a select few who teeth whitening is not recommended. See “Who should NOT undergo teeth whitening” below…

Q. How long does the treatment take?

A. A single treatment takes 20 minutes and produces guaranteed instant results. We do also offer double and triple treatments for people with severely stained teeth.

Q. How does the gel work?

A. The gel is a water-based product with an extra oxygen molecule (H2O2). The extra oxygen molecule helps to gently penetrate through the dentin and enamel removing the discoloured proteins.

Q. How white will my teeth get?

A. Your teeth will typically whiten between 2-8 shades with a single treatment.

Q. Who should NOT undergo teeth whitening?

A. Any of the following: pregnant or lactating women, people with poor enamel or decalcification caused by excessive use of fluorides, people with periodontal disease including gingivitis or gums in poor condition, people who wear braces or who had their braces removed less than 6 months ago, people who recently had oral surgery, people with decaying teeth or exposed roots, people with open cavities, people with a history of allergic reactions to peroxide products, people with silver fillings in, near or behind the front teeth, people under the age of 13. Such conditions are rare so it can be assumed that over 90% of people can undergo and benefit from teeth whitening

Q. Can all teeth be whitened?

A. Carbamide and Hydrogen Peroxides are proven effective for removing the most common stains caused by lifestyle habits (red wine, coffee and tea, tobacco, etc). However, other types of stains such as those caused by tetracycline, certain antibiotics or excessive fluoride may also cause tooth discolouration and may be more difficult to whiten. Artificial dental work such as crowns, bonding, caps, veneers, bridges or composite fillings will whiten but not any whiter than when they were first put in. Artificial teeth will not be damaged or affected by the peroxide. Customers with artificial teeth wishing to whiten their natural teeth can use our products. In general, results will vary from customer to customer depending on their enamel and its reaction to peroxide.

Q. Does teeth whitening cause sensitivity?

A. WaveLight Advanced Teeth Whitening treatments result in minimal to no sensitivity. Mild tissue (gum) irritation (a tingling or stinging sensation we mention in the guide) may occur during the whitening process, but this usually only occurs during the procedure and subsides completely shortly after finishing the treatment. If sensitivity persists, use a toothpaste developed for sensitivity.

Q. Why did I get white spots on my gums?

A. Blanching (whitening of the gums) occurs occasionally. The gums return to their normal colour usually within less than 24 hours.

Q. Why did I get white spots on some of my teeth?

A. Possible white spots or demineralization may appear on people who have had braces or who have porous enamel, but this will typically disappear within 24 hours.
