Tooth Whitening FAQ’s

What causes tooth discolouration?

There are many causes. The most common include aging and consumption of staining substances such as coffee, tea, colas, tobacco, red wine, etc. During tooth formation, consumption of tetracycline, certain antibiotics or excessive fluoride may also cause tooth discoloration.

Is whitening safe?

Yes. Extensive research and clinical studies indicate that whitening teeth under the proper supervision is safe. In fact, whitening teeth is considered the safest cosmetic dental procedure available.  Tooth whitening products are not recommended for children under 13 years of age and pregnant/lactating women.

How long do the results last?

By following some simple post teeth whitening care instructions, your teeth will always be lighter than they were before. To keep your teeth looking their best, we recommend flossing, brushing twice daily, and regular dental hygiene cleanings.

How does Chairside Teeth Whitening work?

The whitening gel’s active ingredient is hydrogen peroxide. As the hydrogen peroxide is broken down, oxygen enters the enamel and dentin, leaching coloured substances while the structure of the tooth is unchanged. The light aids in activating the hydrogen peroxide and helps it penetrate the surface of the tooth.

Are there any side effects?

Sensitivity during the treatment may occur with some patients.   On rare occasions, minor tingling sensations are experienced immediately after the procedure but always dissipate.

Does teeth whitening damage existing dental restorations?

Over 10 years of clinical use of whitening products containing 10% carbamide peroxide have not shown any damage to existing fillings.  Keep in mind that existing restorations such as tooth-colored fillings, crowns, bonding, veneers, and bridges do not lighten. This means that any pre-existing dental work may need to be replaced to match the new tooth shade achieved in the natural teeth, should a bleaching process proceed.

Does insurance cover the cost of whitening procedures?

No. Dental insurance does not typically cover the cost of tooth whitening.
