Pearly whites are so often sought after as the “ideal” smile, but that doesn’t mean that off-white teeth are unhealthy.

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 pearly-white smiles on social media but are hesitant about using teeth whitening strips for yourself, you’re in the right place.

Read on, because we share what you need to know about teeth whitening strips (including whether they’re good for your teeth) and our top picks 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. That means, they chemically break down the stains on your teeth, unlike whitening toothpaste, which contains abrasive ingredients that physically scrub the stains off your teeth.

Teeth whitening strips come in pairs of two translucent “stickers”. The strips are 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.

How long you leave the teeth whitening strips on and how often you use them will vary from product to product, so it’s best to 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, 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, 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 then accumulate 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 short, 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, such as 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 could 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 that’s best for your teeth is to first consult your dentist!

How To Use Teeth Whitening Strips?

While using a whitening strip may appear quite straightforward, according to @tiffkimmm, a dental hygienist on TikTok, there are some application tips that can help with your teeth sensitivity!

To begin, floss your teeth to remove as much plaque and debris as possible for the best results. Then, cut your whitening strips in half and apply them to your dry teeth without wrapping the strips behind them.

Not only will this reduce the sensitivity of your teeth, but it will also save you money! Finally, if you wear retainers, put it on over the strips for added security.

Which Teeth Whitening Strips Work Best?

White Republic Teeth Whitening Strips Fast-acting and gentle on gums

White Republic gained popularity for their teeth whitening kit that uses an innovative LED technology, but their classic and fast-acting whitening strips are not to be underestimated as well!

Visible improvements can usually be observed after just one application, but completing the full 14 days treatment will give you the best and most lasting results.
