What are Teeth Whitening Strips?

Teeth whitening strips are a popular and cost-effective way to whiten your teeth at home.

Most strips are made of a flexible plastic substance coated with a thin layer of whitening gel. This gel is typically made of hydrogen peroxide or carbamide peroxide

These peroxides penetrate your enamel and reach the discolored molecules inside your teeth. ​The whitening agent's oxygen molecules interact with the discolored teeth molecules, gently lifting stains.

Whitening Group 5

You’ll leave the strips on for up to 30 minutes (depending on the brand). During this time, the gel penetrates your tooth enamel, gradually lifting stains and brightening your smile. 

All of the products below have been reviewed and endorsed by Dr. Khushbu Aggarwal, one of NewMouth's experienced dentists.

Aside from clinical dentistry, Dr. Aggarwal also consults for several organizations, including Dr. Clobo and Kaplan. She obtained her Doctor of Dental Surgery degree in 2014 from UCLA School of Dentistry and completed a one-year general dentistry residency in a hospital setting.

Disclaimer: NewMouth recommends LED teeth whitening kits over whitening strips. While more expensive, LED kits typically provide faster results and don't need to be used as often. Hismile PAP+ Teeth Whitening Kit and Snow® Teeth Whitening Kit are two great options.

How to Use Teeth Whitening Strips

Most directions for whitening strips consist of the same basic steps. Read the instructions carefully before applying, as they can vary. 

In general, this is how you should apply whitening strips: 

  1. One packet of whitening strips contains an upper strip and a lower strip
  2. Remove both of the strips from the package
  3. If necessary, cut the strips to match the exact height of your teeth
  4. Remove the adhesive from the strips and gently place them on your teeth
  5. Leave the whitening strips on your teeth for the amount of time listed in the directions
  6. Remove the strips and rinse your mouth with water
  7. Refrain from brushing your teeth for at least two hours
  8. Repeat the whitening process (depending on the directions)
  9. Do not whiten your teeth more often than recommended

Are Whitening Strips Safe?

Whitening strips that contain hydrogen or carbamide peroxide have been shown to whiten teeth over time.1,2,3 When the manufacturer's instructions are followed, peroxide-based teeth whitening products are safe to use.1

According to Dr. Casey Lau, the Chief Dental Officer at Elims, the benefit of using hydrogen peroxide is that most of its whitening power occurs within the first 30 minutes. Carbamide peroxide breaks down into hydrogen peroxide and urea, but its whitening powers usually take longer.

Over long periods of time, hydrogen peroxide at high doses can damage enamel. However, many studies have been done with hydrogen peroxide in dental products which showed that it is perfectly safe if used the correct way.

Dr. Casey Lau

Potential Side Effects of Whitening Strips

The real issue with hydrogen peroxide is that it is an oxidant that can irritate your gums if used incorrectly. It is an antiseptic that kills bacteria and has been used to treat gum disease. But when the treatment times are really long, it can damage tissues.

Some side effects of whitening strips include:

  • Tooth sensitivityTooth sensitivity is the most prevalent side effect of whitening strips. It occurs because the dentin is exposed during the bleaching process.5 Dentin is the layer below your tooth enamel. Sensitivity is typically nothing to worry about and should go away within a few days.
  • Gum irritation – Gum irritation is common with whitening strips because it's difficult not to place them on your gums. To prevent this, cutting the strip to match the height of your teeth before applying is recommended.
  • Enamel erosionEnamel erosion (worn down enamel) is a less common side effect. But it can still develop if you overuse whitening strips. Make sure you read the manufacturer's instructions before using any whitening product.  

Ingredients Found in Whitening Strips

In addition to hydrogen or carbamide peroxide, the following ingredients are commonly found in whitening strips:

  • Polyethylene –Most whitening strips are made of polyethylene, one of the world's most common plastics. It is lightweight, flexible, and non-toxic, making it ideal for the base of a whitening strip.
  • PVP (polyvinylpyrrolidone) and carbomer – These are adhesive agents. They help the strips bind to your teeth. Both of these chemicals are safe and non-toxic. However, if overused, they can cause gum irritation.
  • Water – It prevents the carbomer from dehydrating your teeth.
  • PEG (polymerization ethylene glycol) – This is a common thickener in cosmetic products. The PEG acts to thicken the gel and make it sticky.
  • Glycerin – Glycerin is a sweet, non-toxic compound. It is used as a humectant to thicken the gel and help the strips stay in place.
  • Acrylates copolymer – This binds the gel and keeps the strip in one piece.
  • Sodium hydroxide – Also known as lye or caustic soda, sodium hydroxide neutralizes the pH in whitening strips.
  • Sodium saccharin – Sodium saccharin is an artificial sweetener used to improve the taste. It does not contain sugar.

Who Shouldn’t Use Whitening Strips?

Do not use whitening strips if you have:

  • Cavities
  • Worn down enamel
  • Gum disease
  • Braces
  • Exposed tooth roots
  • Or if you are pregnant or planning to become pregnant

Whitening strips are safe for fillings, crowns, veneers, and other restorations but will not whiten them like your natural teeth. 

If you are allergic to peroxide, all-natural whitening strips are available. These alternatives are not as effective at removing stains. However, they can help remove plaque and debris and improve bad breath, ultimately enhancing your teeth' color and health.

Whitening Strips vs. LED Whitening Kits

LED teeth whitening kits incorporate a special light that has been shown to speed up the whitening process. Whitening strips do not use a light. 

Remember that an LED light will not whiten your teeth if used alone. It helps speed up bleaching when combined with a whitening agent (peroxide). When this interaction occurs, the blue LED light penetrates your tooth enamel and removes stains.

One study found that an LED light reduced treatment time and sensitivity by 53 percent.4 It took the non-light group over two hours to achieve the desired whiteness. The LED light group saw the same results after 72 minutes.4

Although LED whitening kits can lift teeth stains quickly, they are more expensive and time-consuming to use (up to $200 per kit). Whitening strips cost between $20 and $50 for 14 or more treatments. 

Whitening Strips vs. Professional Teeth Whitening 

Dentists do professional whitening in their offices, closely monitoring the process to ensure it's pain-free and controlled. On the other hand, whitening strips can be used at home, but carry a higher risk of side effects like tooth sensitivity and gum irritation.

Unlike at-home systems, dentists use stronger bleaching agents that produce immediate results. Over-the-counter whitening strips usually have 6 to 14 percent peroxide, while professional whitening gels contain 15 to 43 percent peroxide.

In-office whitening typically takes an hour and makes your teeth two to three shades lighter in one visit. You only need touch-ups every six months. Whitening strips require more maintenance and don't show immediate results.

However, professional whitening is more expensive, ranging from $500 to $1,500 per treatment. Whitening strips cost between $20 and $50 for 14 or more treatments.


Whitening strips are a great option to whiten your teeth at home. They're safe, but they should be used properly to prevent dental problems. If you're unsure about a product's safety, it's best to consult with your dentist.
