Safest Teeth Whiteners
The safest ways to whiten your teeth explained
Teeth whitening strips are one of the most popular and cost-effective at-home teeth whitening products. They are made of soft, flexible plastic (such as polyethylene). This is coated with an adhesive to keep them on your teeth.
The other main (active) ingredient in a whitening gel is either hydrogen peroxide or carbamide peroxide. These are safe and effective whitening agents used in both professional and at-home treatments.
Natural teeth whitening strips don’t use peroxide ingredients. They use essential oils and botanicals to gently and gradually remove stains. These products are safe but generally not as effective as peroxide treatments.
Yes, teeth whitening strips are an effective way to whiten teeth, according to the American Dental Association (ADA).1
The following products have received the American Dental Association (ADA) seal of acceptance:
Even though these are the only products that the ADA has accepted, Crest whitening strips are not the only safe and effective whitening strips. However, you can use these products with confidence.
Whitening strips work by covering your teeth in a whitening gel that has hydrogen peroxide or carbamide peroxide. This gel strips off surface stains. It also saturates your tooth enamel and dentin to remove intrinsic staining within your tooth.
The following ingredients are common in tooth whitening strips:
Most whitestrips are made from polyethylene. It is one of the most common plastics in the world. Because it is lightweight, flexible, and non-toxic, it is ideal for the base of a whitening strip.
These are the main whitening ingredients in a whitening strip. They are natural and safe bleaching agents.
PVP and carbomer 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 is included in the gel to prevent carbomer from dehydrating your teeth.
PEGs are humectants. These are thickeners commonly used in cosmetic products. The PEG acts to thicken the gel and make it sticky.
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 is another common ingredient in cosmetics. It is used to bind the gel and keep the strip in one piece.
Sodium hydroxide is also known as lye or caustic soda. It is commonly used in food preparation. It is used in the whitening strip to adjust the pH to neutral.
Sodium saccharin is an artificial sweetener used to improve taste.
Learn about the safest ways to whiten your teeth.
Yes, if used correctly, most whitening strips are a safe way to whiten teeth.1, 2, 3 However, if they include the ingredient chlorine dioxide, they can damage your enamel. This is a chemical oxider and acid that is used to clean swimming pools and strips away your enamel.
It is crucial to follow the instructions on your whitestrips exactly. If you use them more frequently or for longer times than recommended, you could damage your tooth enamel and gum tissue.
Even though whitening strips are generally acknowledged safe and are even recommended by dentists, some potential side effects may occur:
Applying white strips can be difficult. They cannot fit into the small crevices or spaces between your teeth. This can create uneven whitening results. If you do not apply them perfectly, they can leave stained, uneven spots on your teeth.
This is rare, but if you are allergic to adhesives, you may experience an allergic reaction.
Using whitening strips too frequently or for too long can damage the enamel on your teeth. This can lead to sensitive teeth and an increased risk of tooth decay and cavities.
Sensitive teeth are one of the most common side effects of whitening strips. If your enamel gets stripped away, it can expose the dentin of your teeth. This can increase tooth sensitivity to hot or cold food and beverages.
If the strips rest on your gum line, or you use them too frequently, you can irritate the soft tissue of your gums. Both the peroxide whitening agent and sodium hydroxide can damage your gums.
Oral microbiome is a scholarly term for your mouth health. Many types of good bacteria are essential for preventing cavities and other oral conditions. The peroxide in whitening gel also kills bacteria. If too many bacteria are killed, it can disrupt the health of your mouth. This can lead to many oral and systemic diseases.4
Whitening strips are one of the cheapest teeth whitening products available. They are generally a safe and effective way to a brighter smile.
Here are the pros and cons of using whitening strips:

While whitestrips are an effective treatment option, there are many ways to get whiter teeth. Let’s see how they stack up against other whitening treatments.
Whitening toothpastes and mouthwashes can potentially remove stains on the outside of your teeth.7 However, they do not remove intrinsic stains. Therefore they may reduce staining but do not help whiten your teeth. They are much less effective than other teeth whitening products.7, 8
Products and DIY treatments containing charcoal, acidic fruits, or vinegar have not shown to be effective at teeth whitening.7
Whitening toothpastes, mouthwashes, and DIY treatments have little to no whitening effect on your teeth.
At-home LED teeth whitening kits are just as effective as whitening strips.3 First, the user applies a whitening gel containing hydrogen carbamide peroxide. Then they activate an LED light that reduces treatment time and tooth sensitivity.9
LED teeth whitening, whitening strips, and professional teeth whitening all produce similar results.3, 10, 11, 12, 13
NewMouth recommends at-home teeth whitening kits due to their effectiveness, ease of use, and minimal side effects.
The risk of adverse side effects is increased with:
Professional teeth whitening at a dental office is another safe and effective way to get a whiter smile. There are many different types of treatments that dentists use. Speak with your local dentist to find out what method they employ.
Professional teeth whitening is equally as effective as at-home LED teeth whitening and teeth whitening strips. However, it costs much more than the other two methods.
