Wanting a brighter, more confident smile is completely natural and there are safe and effective ways to achieve it! Many people are turning to professional teeth whitening in London, Ontario to enhance their smiles and boost their confidence. With so much information online, it can be hard to separate myths from facts.
At Cosmo Dental Centre, we’ve proudly served Argyle in London and the surrounding areas for over 35 years, and we’re here to share the truth about achieving a whiter, healthier smile.

Debunking the Wildest DIY Teeth Whitening Myths
When you’re looking to boost your appearance, it’s easy to fall down the rabbit hole of myths. Let’s tackle some of the most common ones we hear:
Myth 1: You can whiten your teeth with household acid. The idea of scrubbing your teeth with lemon juice or apple cider vinegar is terrible for your smile. While these substances are acidic and might temporarily lift surface stains, they erode your tooth enamel, the protective outer layer of your tooth. Damage to your enamel is irreversible and leads to sensitivity and other dental issues. Leave the citrus for your salad dressing!
Myth 2: Baking soda and charcoal are the secret. These are highly abrasive materials. Think of them as sandpaper for your teeth. Yes, they’ll remove surface stains, but they scratch your enamel just like acid does, which is counterproductive.
Myth 3: Whitening results are permanent. Wouldn’t that be nice? Unfortunately, even the best teeth whitening treatments aren’t permanent. They fade over time, especially if you enjoy coffee, red wine, or other staining foods. This isn’t a flaw in the treatment, it’s just life! Regular touch-ups and excellent oral care, which you can receive from our dedicated team at Cosmo Dental Centre, are essential for maintaining your results.
When is Professional Teeth Whitening Recommended?
If you’re unhappy with the colour of your teeth, a consultation is always the first step. Professional teeth whitening is an excellent option for most people looking to enhance their smile. However, your dentist will first want to ensure your mouth is healthy.
It’s also crucial to remember that whitening only works on natural tooth structure. If you have existing dental crowns or dental veneers, the colour won’t change, which could result in a mismatched smile. Our team specializes in cosmetic dentistry and can offer solutions that help you achieve your desired brighter shade. Our comprehensive approach to general dentistry ensures that we examine your entire smile before recommending any treatment.
