Do Teeth Whitening Strips Work?

07 April 22.

Americans reportedly spend $1.4 billion annually on over-the-counter teeth-whitening products to eliminate the effects of cigarettes, coffee, red wine or simply age. Almost universally, teeth darken with age. For most older people, their teeth turn brownish-yellow – not necessarily because of smoking, coffee, or wine. Our hair turns white, our teeth turn yellow. I wish it were the other way around. Other teeth turn gray. There is a wide range of normal conditions.

How Do Teeth Whitening Strips Work?

Whitening strips are made of a flexible material coated with hydrogen peroxide or carbamide peroxide and an adhesive to hold them firmly in place. When the hydrogen peroxide comes in contact with your teeth, it oxidizes, which bleaches your teeth and makes them look whiter. Urea peroxide works in a similar way but contains acids that also break down stains.

Staining can be divided into two categories: extrinsic staining and intrinsic staining.

Extrinsic staining

affects the exterior of the tooth and is mainly caused by environmental factors, such as


Certain foods and beverages, such as coffee, wine, blackberries


Exposure to metals such as iron or copper

Intrinsic staining

affects the interior of the teeth. It is caused by the following factors.

Age-related enamel erosion



Exposure to high levels of fluoride

Impaired tooth development

Whitening strips target both extrinsic and intrinsic stains

Teeth whitening strips can target both types of stains. Stains caused by aging, genetics, smoking, or coffee are usually the fastest responding sources to bleaching. Yellow aging stains also respond well. Whitening strips are best used when you are trying to make small corrections to the color of your teeth.

Why Use Teeth Whitening Strips?

Who doesn’t want their smile to be as bright and white as the stars on the silver screen? People want years of stains due to poor oral habits and hygiene that may magically disappear overnight. Teeth whitening strips give them that hope.

There are many reasons why teeth lose their whiteness and become discolored, yellow, or discolored. One of the most common causes is chewing tobacco. In many countries, tobacco is used in many forms. Smoking is known to stain teeth because it contains nicotine.

Another common substance that discolors teeth, in the long run, is the coloring agents in beverages. Sometimes, as people age, they notice that their teeth lose their bright white color and slowly turn yellow. Physical and mental trauma can also stain teeth. In some cases, medications can cause teeth to lose their color, making them look dull and yellow.

Do Teeth Whitening Strips Work?

Yes, although it depends on the concentration of the whitening ingredient. Professional whitening kits used by dentists will contain higher concentrations of hydrogen peroxide and therefore will have more visible results after a shorter period of time.

You need to check the ingredients to make sure you are using the most effective veneers. When properly formulated, hydrogen peroxide and carbamide peroxide are the safest and most effective chemicals for whitening teeth. Some methods do use other agents, such as sodium perborate, but these are usually considered less effective.

Even if you don’t notice any improvement after a few days, it’s important to continue using your test strips – they’re designed to be used as a complete course, and you should only evaluate the difference at the end. Try taking pictures of your teeth before you start testing to make it easier to compare.
