A whiter smile can do wonders for confidence, and teeth whitening strips are just one brightening product on the market that can assist in the removal of stains. We've looked into the types of products currently on the market, how long they take to work and where you can find them online.

Do teeth whitening strips work?

Yes. The main whitening ingredient in teeth whitening strips is hydrogen peroxide, which is also one of the active ingredients used by dentists for professional, in-office treatments. However, at-home treatments don't use as high of a percentage of hydrogen peroxide as dentist treatments so may not be as effective.

There's also natural alternatives in the form of sodium bicarbonate or charcoal formulas. Although they don't have the same intensity as peroxide treatments, they may help in the whitening of surface stains.

Types of teeth whitening strips

There are currently two types of whitening strips on the market, including:

  • Hydrogen peroxide formula: Hydrogen peroxide is one of the most popular teeth whitening ingredients and a high percentage of the products on the market are formulated with it. Keep in mind that it can cause mild irritation of the teeth and gums.
  • Peroxide-free formula: These are a natural alternative for people after a whiter smile without peroxide treatment. The active ingredient in these formulas is either sodium bicarbonate or charcoal.

How to use teeth whitening strips?

Teeth whitening strips come in a three step process. First, you'll want to peel off the whitening strip from the backing liner. From here, you simply place the strip across the front of the teeth you want to treat and fold the rest over the other side of your teeth. Try not to move your mouth around too much when the treatment is in as they can slide around. Keep the strip on for the recommended amount of time before removing and disposing of it.
