Why consider teeth whitening?

Why consider teeth whitening? The natural shade of teeth ranges from light grey to yellow and naturally darken with age. Their appearance can be affected by the accumulation of surface stains acquired from the use of tobacco products, the consumption of various foods and drinks, and by our skin tone/genetic make-up.

Did you know that new patients recieve free teeth whitening with their exam and x-rays? On top of that, a portion of proceeds from new patients' exams and x-rays are donated to SickKids Hospital! Contact us now to take advantage of this great offer!

  • What are the advantages of in-office teeth whitening?

    If your smile is important to you, then in-office teeth whitening is the most effective treatment available for you. The popularity of teeth whitening in Thornhill is growing rapidly and has shown to be one of the most affordable solutions to improving your smile.

    Did you know that getting a healthy-looking smile can enhance your quality of life? A healthy smile can give you a boost of self-confidence and can even enhance your likelihood of being successful in your career.

  • Teeth whitening offered at Doncaster Dental Studio

    Whether you want your teeth whiter immediately or over a couple of days, in-office teeth whitening is your solution.

    We provide two types of teeth whitening solutions at our Thornhill dental clinic:

    1. Zoom In-Office Teeth Whitening
    2. Take-home whitening kits (consisting of a bleaching gel that is applied to the teeth with custom upper and lower trays)
  • In-office vs. at-home teeth whitening

    With the rise of popularity of take-home teeth whitening, it may be tempting to follow the trend and try whitening your teeth yourself. However, before you do so, keep in mind a few limitations of these kits:

    1. They are not made with a custom-fit, so they may irritate your gums, especially if your teeth or gums are sensitive.
    2. They are not as strong, so they will take many more applications and more time to achieve the same results.
    3. They can be costly over the long-run because of the need for multiple applications.

    On the other hand, our Thornhill dental office's in-office whitening services are stronger and you can whiten your teeth more quickly, as well as void irritation. For more information on the differences between in-office and take-home whitening kits, contact us!

  • How in-office teeth whitening works

    In-office teeth whitening allows for maximum teeth whitening in a minimal amount of time. One of our Thornhill dentists will place a gel solution into dental trays and insert them into the mouth. The trays are cured using an LED light to activate the gel, providing powerful whitening with cellular stimulation. Hydroxyl penetrates the enamel to whiten and break down stains into much smaller particles, creating a whiter, brighter smile.

    This process penetrates the tooth but does not damage the enamel or any crowns, veneers, etc. that the patient might have. It also causes little to no sensitivity, a key difference from take-home kits. The entire process takes approximately 30-60 minutes and will have you leaving the office with a noticeably whiter smile!

  • Where can I whiten my teeth professionally?

    An assessment with a dentist is needed before teeth whitening to identify whether or not bleaching can provide the expected result and to ensure there are no issues that should be addressed prior to treatment.

    Why waste your time with strips and paint-on gel? Take advantage of teeth whitening with minimal effort using one of Doncaster Dental Studio's whitening options! Call our Thornhill dental office to find out about our teeth whitening promotions and schedule your evaluation session.

I was extremely impressed with the professionalism of Dr. Shawn and his well organized office team. Dr. Shawn does an incredible job of explaining what he is doing while working on your teeth.
