A bright, white smile is something many people want, and it's easy to see why DIY teeth-whitening kits are so appealing. They're widely available, often inexpensive, and promise noticeable results from the comfort of your own home.

But before reaching for an over-the-counter whitening kit, it's worth understanding that more whitening doesn't necessarily mean better results.

Whitening Isn't One-Size-Fits-All

Teeth can become stained or discoloured for many reasons. Coffee, tea, red wine, tobacco, certain foods, and simply getting older can all affect the colour of your teeth.
However, not every type of discolouration responds to whitening in the same way. Fillings, crowns, veneers, and other dental restorations, for example, don't whiten like natural tooth enamel does.
That's one reason a dental assessment is helpful before starting treatment.

Too Much Whitening Can Cause Problems

Most whitening products use peroxide-based ingredients to lighten stains. When used incorrectly, products with higher concentrations or prolonged exposure can cause tooth sensitivity and irritation to the gums.
Poorly fitting whitening trays can also allow the whitening gel to come into contact with your gums, potentially causing irritation.
Some DIY products may also contain questionable ingredients or make claims that aren't supported by good evidence. It's important to know exactly what you're putting on your teeth and gums.

A Safer Approach to a Whiter Smile

Professional teeth whitening allows your dentist to assess your oral health first and recommend an option that's appropriate for you. Your dentist can also help you understand what kind of results you can realistically expect.

A brighter smile is great—but healthy teeth and gums should always come first.
