Teeth Whitening in Thornhill
A bright, white smile can leave a lasting impression! If your teeth have lost their natural vibrancy and appear dull or yellowed, you’re not alone. Everyday habits—such as drinking coffee, tea, or red wine, or consuming certain foods—can gradually stain your teeth. Fortunately, our professional teeth whitening treatment in Thornhill can help you restore a radiant, confident smile!

Common Causes of Tooth Discoloration
It’s understandable to feel concerned if your smile isn’t as bright as you’d like; knowing the causes can help find solutions. While everyday food and drinks play a part, tooth discoloration often has multiple factors beyond the initial accumulation of surface stains.
For instance, using tobacco products can unfortunately cause stubborn yellowing, and deep stains might form inside the tooth itself.
Aging also naturally thins your protective tooth enamel, making teeth less vibrant and shifting them from their original natural shade.
Professional Teeth Whitening – Safe & Effective
Our take-home whitening kits deliver professional-grade whitening, helping you achieve noticeably whiter teeth and work towards your desired, attractive smile, all from the comfort of your home. Your Thornhill Smiles dentist provides a complete system, including:
✔ Custom-fitted whitening trays, made just for you. These ensure even whitening and protect gums for a healthy smile.
✔ A high-quality whitening formula designed for safe, gradual brightening.
✔ Detailed instructions to help you achieve optimal results safely.
How Take-Home Whitening Works
Following your dentist’s guidance, you’ll simply apply the gel in
your custom trays and wear them daily. You can expect noticeable progress toward brighter teeth within days, although the full treatment time varies for each person. This convenient at-home method provides affordable treatments compared to in-office procedures, making it an excellent option. With consistent use, you’ll see beautifully brightened teeth and enjoy impressive, lasting results.


Our Teeth Whitening Procedure
Here’s how the will for our professional take-home whitening works:
First, we’ll discuss your goals for this cosmetic procedure and check your oral health to ensure this type of treatment is right for you. If all looks good, we will use a digital scanner to scan your mouth and make digital molds to use for future whitening trays.
How Are the Custom Trays Made and Used?
Those digital molds are used to fabricate your personal custom whitening trays.
- At a follow-up fitting appointment, we ensure they fit perfectly for comfort and optimal whitening
- We then guide you through using the bleaching solution (typically containing hydrogen peroxide or carbamide peroxide)
- This includes explaining exactly how much gel to use and the prescribed wear times

Frequently Asked Questions About Teeth Whitening
What if I experience tooth sensitivity during whitening?
Some temporary sensitivity is common with many bleaching methods, but it’s typically manageable. Your dentist can provide specific advice, may recommend desensitizing products, or adjust your treatment for a comfortable, positive experience.
How do professional whitening products compare to over-the-counter?
Dentist-prescribed systems use custom trays and professional-strength gels for safer, more predictable results than most generic over-the-counter products or whitening products. This bespoke approach is generally considered a more effective solution for noticeable whitening.
Will whitening work on crowns, veneers, or fillings?
Teeth whitening treatments primarily lighten the colour of teeth that are natural teeth. They do not change the shade of existing dental restorations like crowns, veneers, or fillings.
Is teeth whitening considered one of the invasive procedures in cosmetic dentistry?
No, professional teeth whitening is considered a minimally invasive cosmetic procedure compared to options like veneers or crowns. It simply involves applying a bleaching solution to the tooth surface without altering its structure.
How white can I expect my teeth to get for a beautiful smile?
Whitening results vary depending on your starting color of teeth and the type of staining. Your dental professional can discuss realistic expectations for achieving brilliant teeth and a healthy-looking smile during your consultation.
