What is Professional Teeth Whitening?
Over time, teeth naturally darken as they become stained and discoloured, both inside the tooth and on the surface. This can happen for a number of reasons, including regular consumption of coffee, tea, or red wine, smoking, and inconsistent dental hygiene.
Professional teeth whitening offers a safe and effective way to restore the brightness of your smile. The process is simple, non-invasive, and works by targeting and removing stains to change the natural colour of your teeth.
At Platinum Dental Care, our team can help you determine whether teeth whitening is the right option for you, and what shade of white you should be aiming for.
Treatment Options To Fit Your Lifestyle
In-Office or At-Home Teeth Whitening Options
Our goal is to help you achieve a whiter, brighter smile your way. That’s why we offer two convenient treatment options: one in our office with the support of our dental team, and another you can do at home with a personalized plan. Either way, you’ll be taking a step toward the smile you’ve always wanted.
How Teeth Whitening Works
Our dentists use a peroxide-based gel for teeth whitening, which works by sending oxygen molecules into the teeth to break down the stains that cause discolouration, both on the surface and deeper within the tooth.
When applied by a dental professional, these gels are carefully controlled to ensure safety and effectiveness, gradually lightening the natural colour of your teeth and revealing a brighter, more radiant smile.
What are the Benefits of Teeth Whitening?
Your smile is often one of the first things people notice about you, and having a brighter smile can give your confidence and self-esteem a real boost.
Feeling good about your smile can also motivate you to take better care of your teeth, which can have a positive effect on both your oral health and overall wellbeing.

In-Office Teeth Whitening
At our office in North York, we offer a teeth whitening treatment that’s safe, efficient, and effective.
The process is simple: a protective barrier is first placed around your gums, and then a thin layer of whitening gel is applied to each tooth. After your treatment, you can enjoy a noticeably brighter, whiter smile.
Personalized Take-Home Teeth Whitening
You can also brighten your smile from the comfort of your own home with our take-home whitening option.
We start by taking impressions of your teeth to create your customized whitening trays. Then, we simply apply the whitening gel to the trays and wear them as directed. By the end of the treatment, your teeth should be noticeably whiter and brighter.
Teeth Whitening FAQs
Read the answers to our most frequently asked questions about teeth whitening at Platinum Dental Care.
-
How long do the effects of teeth whitening last?
Teeth whitening isn’t permanent, and everyday foods and drinks like coffee, wine can gradually cause stains to return. How long your results last can vary depending on your diet and habits. With good oral hygiene, most people find they only need a touch-up about once a year to keep their smile bright.
-
Does insurance cover the cost of teeth whitening?
Dental insurance does not typically cover the cost of teeth whitening.
-
Does teeth whitening make teeth more sensitive?
A common short-term side effect of teeth whitening is temporary sensitivity, which usually fades within a few days after treatment. To help minimize any discomfort, we recommend using an anti-sensitivity toothpaste before your whitening session and continuing for at least two weeks afterward.
-
Do teeth whitening products work on all stains?
Teeth whitening tends to work best on brown and yellow stains, while some types of discolouration may not respond to whitening at all. If achieving a brighter smile is important but your teeth have stubborn stains, your dentist may suggest alternative cosmetic options, such as dental crowns or veneers, which could provide a more effective solution.
-
Does teeth whitening work on dental restorations?
Unfortunately not. Teeth whitening only works on natural teeth and will not work on existing dental restorations such as fillings, crowns, or veneers. If crowns or veneers are part of your treatment plan, teeth whitening should take place before you receive your dental restorations.
-
Will teeth whitening damage my tooth enamel?
When used as directed under the supervision of a qualified dentist, teeth whitening is very unlikely to harm your enamel. However, it is important to always consult with your dentist to make sure any whitening products are used safely. If you notice any pain, sensitivity, or discomfort in your mouth, be sure to let your dentist know.
