Why Stains Develop and Prevention
Before we dive into how whitening strips work, let’s first understand why your teeth get stained in the first place.
Two main types of stains affect your teeth: extrinsic and intrinsic.
Extrinsic Staining
Extrinsic stains occur on the surface of your enamel, the hard outer layer of your teeth. They are caused by external factors such as food and poor oral hygiene. These substances contain pigments or acids that can adhere to and discolor your enamel over time.
The good news is that extrinsic stains are usually easy to remove with regular brushing, flossing, and professional cleaning.
Intrinsic Staining
Intrinsic stains occur within the dentin, the inner layer of your teeth beneath the enamel. They are caused by internal factors such as aging, genetics, or fluorosis. These factors can affect the formation of your dentin and change its color from yellow to brown or grey.
Unlike extrinsic stains, intrinsic stains are harder to remove with brushing. They require more intensive whitening treatments that penetrate the enamel and reach the dentin.

Types of Teeth Whitening Strips
Different whitening strips that whiten your teeth are available in the market. Here is a summary of the main types of whitening strips.
Peroxide-based Teeth Whitening Strip
It is the most common and effective whitening strip that uses hydrogen peroxide or carbamide peroxide as the active ingredient. It can whiten your teeth by one to three shades on average after using it for a few days or weeks. However, it can also cause side effects, such as tooth sensitivity.
Charcoal Teeth Whitening Strip
This natural type of whitening strip uses activated charcoal as the main ingredient. It can absorb stains, toxins, and bacteria from your teeth and mouth and improve oral health. However, it may not be practical or safe for your teeth as little scientific evidence supports its claims.
Non-peroxide Teeth Whitening Strip
To whiten teeth, this gentle whitening strip uses alternative ingredients such as sodium bicarbonate, sodium chlorite, or enzymes. It can be safer and more suitable for people with sensitive teeth. However, it may be less effective than peroxide-based products and require more frequent applications.
Enzyme Teeth Whitening Strip
To whiten teeth, this natural whitening strip uses enzymes such as papain or bromelain. It can break down the protein bonds and help remove plaque and bacteria from your teeth. However, it may only suit some, as some may be allergic to these enzymes.

Whitening Strips Target Both Extrinsic and Intrinsic Stains
Whitening strips are designed to whiten your teeth. They work by applying a whitening agent to your teeth that breaks down the molecules that cause discoloration. The most common whitening agent in whitening strips is hydrogen or carbamide peroxide.
When you apply a whitening strip to your tooth, the peroxide gel reacts with the moisture in your mouth and releases oxygen molecules. These molecules then enter your tooth’s enamel and dentin layers and oxidize the stain molecules, making them smaller and less visible. As a result, your tooth becomes lighter in color and more reflective.
