Teeth whitening treatments are one of the most commonly requested procedures at Dr. Sara Shiewitz Dentistry. Over time, stain-causing foods and beverages, smoking, and thinning enamel can dim the brightest smile. If you are feeling self-conscious about your teeth, Dr. Shiewitz can help you discover the whitening treatment that is best for you. Dr. Shiewitz and our staff believe that patients should have smiles they love to show off. While we offer a range of cosmetic dentistry services to makeover any smile, teeth whitening is the most popular because of the quick and noticeable results.

Why Choose Professional Whitening Treatments Over Drug Store Products?

Although there are tooth-whitening products available in drug stores, these products have varying degrees of success. They also cannot provide the same level of whitening strength as the professional-grade treatments provided at Dr. Sara Shiewitz Dentistry. When done at our North York, ON dental office, the whitening agent is applied to the entire surface of the visible teeth. This custom application is much more precise and thorough than that achieved through drug store products.

Types of Teeth Whitening 

Dr. Shiewitz offers both in-office bleaching and home bleaching via custom fit trays. The best option for achieving maximal results is to do in-office bleaching followed by two weeks of home bleaching.

In-Office Bleaching: Opalescence® Boost

In-office bleaching with Opalescence® Boost requires a 90-minute appointment, with up to three 20-minute bleaching procedures during that time. A pre-treatment colour matching is done, as well as photography. This is repeated at the end of the procedure so you can see the noticeable difference immediately.

Opalescence® Boost contains potassium nitrate and fluoride. Both of these help minimize tooth sensitivity during and after treatment. Boost is a chemically activated gel, so no hot light is needed during the procedure. It is a powerful 40% hydrogen peroxide gel specifically designed for dental bleaching.

Lumibrite® Home Whitening

For Lumibrite® home bleaching, custom fit trays are fabricated in our North York, ON dental office. They fit the shape of the teeth precisely. We provide the bleaching material and instructions on how to apply this at home so you can achieve the brighter smile you desire in a gentle and safe manner.

Whitening and Sensitivity

Sometimes, bleaching can cause tooth sensitivity, particularly to cold. In such cases, bleaching is temporarily discontinued and a fluoride treatment or desensitizing regimen is recommended. Fluoride desensitizes the teeth. We also recommend desensitizing toothpastes such as Sensodyne.

When the sensitivity resolves, your whitening treatment can resume. However, Dr. Shiewitz suggests that after each additional bleaching session, an extra high fluoridated toothpaste be inserted into the custom trays and worn for 30 minutes to help prevent further sensitivity issues. 


Dr. Sara Shiewitz Dentistry offers both in-office bleaching and take home teeth whitening kits so you can achieve the whiter, brighter smile you desire. Call our North York, ON dental office today at (416) 223-4181 to learn more or schedule an appointment!
