Is tooth whitening safe?

Yes. The procedure is safe and effective when done by a dentist during the first visit, and under a dentist’s supervision for subsequent treatments. That said, everyone should first visit a dentist for a thorough examination and diagnosis to ensure you’re a good candidate for a safe, brighter, whiter smile.

How does teeth whitening work?

The bleaching product (usually hydrogen peroxide) is applied on the surface of your teeth using trays that fit snugly on your teeth. The trays stay in place for a short period of time to break down the agent into oxygen, which then penetrates tooth enamel to change the shade of your teeth.

How is teeth whitening different from polishing?

Polishing is done during professional teeth cleaning in order to remove surface stains caused by colored drinks like tea and red wine, tobacco products, foods, and so on. However, polishing cannot change the color of yellowing or stained teeth. Teeth cleaning can help you remove deep stains and discoloration that won’t go away with routine cleaning and polishing.

Will I achieve the results I want?

Yes. Most cases of tooth whitening are successful. That said, the treatments work differently depending on the extent of discoloration or staining at the start of the procedure. Fortunately, your dentist will discuss with you about your treatment plan and inform you beforehand about the best way to whiten your teeth, any difficulties, and even the expected results. This is because dentists are trained to:

• Choose the best treatment plan for your case;
• Estimate the improvement in shade that you will achieve; and
• Inform you how long your treatment will last.

Are there situations when tooth whitening might not work?

Tooth whitening only helps to improve the shade of your natural teeth. This means that it may not be successful when used on:

• Teeth with exposed roots
• Teeth that have been restored with fillings, crowns, veneers, or have received root treatments
• Unhealthy teeth

Please consult your dentist to discuss the expected results of your teeth whitening treatment.
