Having off-white teeth doesn’t mean that your teeth are unhealthy. Still, enamel-clear, pearly-white teeth are so often sought after for an “ideal” smile. Users on TikTok and Instagram have also been showing off their dazzling white teeth, thanks to easy “paste-and-peel” whitening strips that seem almost too good to be true.

If you’ve been admiring these pearly smiles on social media but are hesitant about using them for yourself, then you’re in the right place! Read on, because we share what you need to know about teeth whitening strips and our pick of ones that work to brighten your smile.

What are teeth whitening strips?

Teeth whitening strips are strips of plastic that contain a thin layer of whitening agents like hydrogen peroxide or carbamide peroxide. Since they chemically break down the stains on your teeth, they can be considered gentler than whitening toothpaste, which contains abrasive ingredients that physically scrub the stains off your teeth.

Take them out of the packaging, and you’ll discover that teeth whitening strips come in a pair of two translucent “stickers”. Each strip is worn by first placing them, gel-side down, onto the front of the teeth, aligned with the gums. This is followed by pressing the strips evenly against the teeth, and then wrapping the remaining section of the strip to the back.

The time that you leave the teeth whitening strips on and how often you use them will vary from product to product, so you should check the packaging for specific instructions.

Do teeth whitening strips work on yellow teeth?

Teeth whitening strips really do work on yellow teeth, but mostly on teeth that have been discoloured due to lifestyle habits such as diet and oral hygiene.

When it comes to diet, for instance, one that includes a lot of coffee, tea, or red wine, can result in the accumulation of pigments in the enamel (outer surface) of the teeth, thus leading to discolouration.

If you’re not brushing your teeth well, bacteria can also accumulate on your teeth causing stains to form. People who wear braces might notice yellow stains on their teeth, usually because the areas around the brackets are hard to reach and often neglected; bacteria accumulates and the yellow stains are revealed when the braces are removed.

You should note, however, that even if you brush and floss regularly, your teeth could be a natural off-white colour that’s due to the thickness of your enamel, or age.

In lesser words, teeth whitening strips do work on yellow teeth, but mostly on teeth that are yellow because of stains caused by external factors.

Are teeth whitening strips good for your teeth?

Teeth whitening strips are not all that different from what dentists use to whiten their patients’ teeth in the clinic. The whitening agents used in teeth whitening strips, like hydrogen peroxide and carbamide peroxide, are also used in dentist treatments – only in different amounts. That’s why, teeth whitening strips are typically considered safe, when used correctly and in moderation.

Still, teeth whitening strips have their downsides – they warn of teeth sensitivity and gum irritation, especially when used too frequently or for extended periods of time.

Since the strips are “pasted” onto your teeth, they could also miss out on the spots in between each tooth; the tooth’s flat surfaces might be whitened but the harder-to-reach spots remain yellow.

So, while teeth whitening strips are generally considered safe and are effective at turning your yellow teeth white, the best thing that you can do when choosing a product best for your teeth is to first consult your dentist!
