Teeth Whitening in Newmarket

Explore professional teeth whitening at Tanzil Dental & Associates. Our Newmarket dental clinic offers personalized guidance to help you choose a whitening option suited to your smile and cosmetic goals.

Brighten Your Smile With Professional Teeth Whitening

Professional teeth whitening uses whitening agents to help reduce certain stains and discolouration affecting natural teeth. It can be considered for patients who want a brighter smile without changing the shape or structure of their teeth.


At Tanzil Dental, we discuss your cosmetic goals and assess your teeth and gums before recommending treatment. Depending on your needs, professional whitening may involve an in-office treatment or custom take-home whitening trays. Existing crowns, veneers, and fillings do not whiten like natural enamel.

What to Expect During Your Teeth Whitening Treatment

Your whitening consultation begins with an examination of your teeth and a discussion of the results you hope to achieve. We consider factors such as existing restorations, tooth sensitivity, and the type of discolouration before discussing an appropriate approach.


If take-home whitening is recommended, custom trays may be prepared to fit your teeth and used with whitening gel according to the instructions provided. Some patients experience temporary sensitivity during treatment, and results vary based on individual factors and the cause of staining.

Frequently Asked Questions

  • What is the difference between in-office whitening and take-home whitening trays?

    In-office whitening is performed during a dental appointment, while take-home whitening uses trays and gel according to a prescribed schedule. Both approaches aim to lighten certain stains on natural teeth. Your dentist can explain the available options, expected treatment time, and which method may be appropriate for your oral health and whitening goals.

  • How long do professional teeth whitening results last?

    Whitening results vary depending on your diet, oral hygiene, smoking habits, and the type of discolouration being treated. Coffee, tea, red wine, and tobacco can contribute to new staining. Regular dental care and following your dentist's recommendations may help maintain your results, although additional whitening may eventually be considered.

  • Can teeth whitening cause tooth sensitivity?

    Some patients experience temporary tooth sensitivity or gum irritation during whitening. This can occur because whitening agents interact with the tooth surface and surrounding tissues. Sensitivity is often temporary, but you should tell your dentist about existing sensitivity before treatment and report any discomfort that becomes significant or does not improve.

  • Will teeth whitening change the colour of crowns, veneers, or fillings?

    Whitening agents generally do not change the colour of dental crowns, porcelain veneers, or composite fillings the same way they lighten natural teeth. If you have visible restorations, whitening may create a colour difference. Your dentist can assess these restorations and discuss whether whitening or another cosmetic approach would better suit your smile.

  • Am I a suitable candidate for professional teeth whitening?

    Suitability depends on your oral health, the cause of discolouration, existing dental restorations, and sensitivity concerns. Some stains respond better to whitening than others. A dental examination helps identify concerns such as untreated cavities or gum inflammation that may need attention before whitening is considered.
