With the rise of viral TikTok trends and DIY hacks promising quick teeth-whitening results, dental experts are urging caution.
In an exclusive Q&A with HOLR Magazine, Dr. Derek Chung, dentist and founder of Paste Dental, breaks down the dangers of abrasive at-home methods and explains why sensitivity is becoming a widespread issue among Canadians.
As National Smile Day approaches (May 31st), Dr. Chung offers insights into how Sensodyne Clinical White, a peroxide-free, enamel-safe toothpaste, is changing the whitening game, making it possible to brighten your smile without sacrificing comfort or dental health.
What are the most common mistakes people make when trying to whiten their teeth at home, especially through social media trends like baking soda or charcoal?
One of the biggest mistakes I see is people turning to TikTok whitening trends they find, like using baking soda, activated charcoal, or even lemon juice. These methods may appear harmless, but they can actually be very abrasive and damage the enamel. Once enamel is worn down, it doesn’t grow back, and this often leads to increased tooth sensitivity. I always advise my patients to use products that are clinically tested and enamel-safe, like Sensodyne Clinical White, which is specifically designed for people with sensitivity concerns.
The new Sensodyne Clinical White is peroxide-free. Why is peroxide such a common trigger for sensitivity, and how does this new formula avoid that?
Peroxide is one of the top culprits when it comes to triggering sensitivity during dental whitening. It can penetrate through the enamel and irritate the nerve inside the tooth, which causes discomfort. The peroxide also causes the pores on the enamel to open wider, which allows for air and moisture to penetrate right to the nerve, causing those ‘electric shocks’ of sensitivity! Sensodyne Clinical White is peroxide-free, which makes it a much gentler option for everyday use. It still develops impressive results – clinically proven to whiten teeth up to two shades – but without the pain that often comes with traditional whitening.
Nearly half of Canadians who tried at-home whitening reported increased sensitivity. What are some signs people should watch for that indicate they’re damaging their teeth?
Sensitivity outside of the normal window post-whitening treatment is often the first red flag, especially if you’re noticing pain when eating or drinking something hot, cold, or sweet. If you’re brushing and wincing or avoiding your favourite foods, that’s a sign your enamel may be compromised. Unfortunately, many whitening methods that promise quick results can come with long-term trade-offs if used too often. That’s why products like Sensodyne Clinical White are so important – a whitening product that can be used daily. It helps prevent enamel wear while still helping patients get a noticeably whiter smile.
Why do you think sensitivity is such a widespread issue, and how has it changed the way people approach dental care?
Teeth whitening is THE most common cosmetic procedure in the world. More and more people are trying it, and some of these methods are not safe. At-home whitening methods can lead to increased sensitivity. Sensitivity affects everything from eating to brushing, so it’s not just a cosmetic concern – it impacts quality of life on an everyday level. The good news is that consumers are becoming more educated, and they’re looking for solutions that don’t force them to choose between a bright smile and healthy teeth. Sensodyne Clinical White is a two in one, offering not only the benefits of gentle daily whitening but also 24/7 sensitivity protection. Making it a multi-functional product that allows you to whiten your teeth, but also know you’re doing something good for your sensitivity in general.
Can you explain how Clinical White both whitens and protects enamel at the same time? How does it differ from other whitening products on the market?
What makes Sensodyne Clinical White stand out is its dual action. It can lift stains, even in hard-to-reach places, and gently polishes the teeth for a smoother, shinier finish. At the same time, it offers long-lasting sensitivity protection and is highly enamel-safe. Most whitening products on the market focus only on the cosmetic benefit. This one delivers both – a whiter smile and healthier teeth – without using peroxide.
With National Smile Day around the corner, what advice do you have for Canadians looking to brighten their smiles safely and affordably?
My advice is simple: don’t trade comfort and the risk of damaging your enamel for results. With Sensodyne Clinical White, Canadians now have access to a premium whitening toothpaste that’s effective, affordable, and gentle enough for daily use. Whether you’re a coffee drinker, a red wine lover, or just looking for a confidence boost, you can brighten your smile safely, with low risk of sensitivity. It’s a great way to celebrate National Smile Day with confidence!
