Teeth Whitening: Get the Facts

Teeth whitening suits most people, but not everyone. Healthy teeth and gums are needed for the procedure to be comfortable and to work, and extensive fillings or crowns do not lighten with the rest of the tooth.

Quick summary

Teeth whitening suits most people, but not everyone. Healthy teeth and gums are needed for the procedure to be comfortable and to work, and extensive fillings or crowns do not lighten with the rest of the tooth. A full examination is how suitability is decided. In-chair treatment uses a high concentration peroxide gel, with the gums protected first, and results vary with the cause of the stain.

More and more people today are heading to their dentist’s office to brighten their smiles through teeth whitening treatments. Although you can try to maintain white teeth by limiting foods and drinks that stain or stopping habits like smoking, the truth is that teeth are prone to discolouring over time. If you’re considering undergoing teeth whitening, get the facts before you go.

Is teeth whitening safe?:
Most people are able to have their teeth whitened successfully without any issues. However, not everyone has good enough oral health to safely undergo treatment. Healthy teeth and gums are necessary so that the procedure is comfortable and effective. Patients with extensive fillings or crowns may not be the best candidates. Teeth that have extremely dark stains or discolourations from certain things like medications may not attain desired results.

How do I know if I’m a good candidate?:
A complete oral examination by your licensed dentist is the best way to determine if teeth whitening is right for you. During the assessment, your dentist will look for decay, receding gum lines, fillings, enamel condition, tooth sensitivity and more to decide if treatment is advised. Sometimes dental work can be done to restore oral health and then whitening becomes an option.

What is the process?:
Most professional teeth whitening treatments performed in a dental office are done with a high concentration peroxide bleaching agent and enhanced with special lighting to activate the gel. The dentist usually coats your gums with a product to limit sensitivity, and then the bleaching gel is carefully placed onto your teeth. Light is directed to the area, typically in three 15-minutes sessions. The dentist monitors the entire process for your safety and comfort.

What results can I expect?:
It is important to discuss your specific case with your dentist prior to treatment so that you have realistic whitening goals in mind. The degree of whitening often depends on the level and cause of your tooth discolouration. Some patients achieve a couple of shades brighter, while others whiten up to ten shades.

Questions patients ask us about this

Why do fillings and crowns matter for whitening?
Whitening gel works on natural tooth structure, not on restorations. Fillings, crowns and veneers keep the shade they were made in, so if you have extensive work at the front, whitening the teeth around it can leave the colours mismatched. That is one of the things an examination is looking for before treatment is recommended.
What does the dentist check before whitening?
Decay, receding gum lines, existing fillings, the condition of the enamel and any tooth sensitivity. Sometimes dental work is done first to restore oral health, and whitening becomes an option after that. It is an assessment of whether the procedure will be comfortable and effective, not a formality.
How much whiter will my teeth actually go?
That depends on the level and the cause of the discolouration, and it varies widely — some people gain a couple of shades and others considerably more. Teeth with very dark staining, or discolouration caused by certain medications, may not respond as hoped. Discuss realistic goals with your dentist before you start.
