Do Dissolving Whitening Strips Work?


A bright, dazzling smile is something most people aspire to have. Fortunately, there are numerous options available for teeth whitening on the market today. One popular method is using dissolving whitening strips. These strips, which are applied directly to the teeth, promise to deliver a whiter and brighter smile. But the question remains: Do dissolving whitening strips actually work? In this article, we will explore the effectiveness of these strips and examine their advantages, any potential drawbacks, and the science behind their whitening power.

Understanding Dissolving Whitening Strips:

1. The Science behind Whitening Strips:

To understand how dissolving whitening strips work, it's important to grasp the science behind the process. These strips are typically made of thin, flexible plastic and are coated with a layer of peroxide-based gel. The peroxide gel acts as a bleaching agent that penetrates the enamel of the teeth, targeting and removing stains. When the strip dissolves, it leaves behind a brighter and whiter smile.

2. Advantages of Dissolving Whitening Strips:

One of the key advantages of using dissolving whitening strips is their convenience. These strips are usually clear and discreet, making them easy to wear without drawing attention. Unlike other teeth whitening methods, such as gels or trays, whitening strips have no bulky equipment or messy applications. They are also a cost-effective option, especially when compared to professional teeth whitening treatments performed at dental clinics.

3. Application and Usage:

To use dissolving whitening strips effectively, it's crucial to follow the instructions provided by the manufacturer. Generally, it involves a simple three-step process:

Step 1: Brush your teeth to remove any food particles and plaque.

Step 2: Dry your teeth with a tissue or cloth to ensure the strip adheres properly.

Step 3: Apply the strip onto your teeth, positioning it carefully to cover the enamel surface.

Once applied, you must wait for the recommended amount of time before removing the strip. This can vary from product to product, but it is typically between 5 to 30 minutes. The strips should be used consistently over a period of time as directed to achieve optimal results.

Effectiveness and Results:

1. Whitening Power:

The effectiveness of dissolving whitening strips in achieving whiter teeth largely depends on the concentration of the bleaching agent and the frequency of use. Most reputable brands offer strips with peroxide concentrations between 6% and 10%. This concentration range is considered safe and effective in removing stains and discoloration from the teeth's surface. However, it might not be as potent as professional treatments, which often have higher concentrations of peroxide.

2. Stain Removal:

Dissolving whitening strips primarily target external stains caused by factors like consuming coffee, tea, or smoking. These strips work by absorbing into the enamel and breaking down the stain molecules, revealing a brighter shade of white. While they can provide satisfactory results for mild to moderate stains, they might struggle with deeper, intrinsic stains caused by a variety of factors, including genetics or certain medications. In such cases, professional treatment or alternative whitening methods may be more effective.

3. Time and Consistency:

One important aspect to consider when using dissolving whitening strips is that they require both time and consistency to deliver noticeable results. As mentioned earlier, the concentration of the bleaching agent in the strips is lower than professional treatments. Therefore, it may take several weeks of regular use to witness a significant difference. Patience and adherence to the recommended application routine and frequency are essential for achieving desired results.

Potential Drawbacks and Precautions:

1. Tooth Sensitivity:

One of the most commonly reported side effects of using dissolving whitening strips is tooth sensitivity. The peroxide gel, although safe for most individuals, can temporarily cause sensitivity to hot or cold substances. However, this sensitivity usually subsides after the whitening treatment is complete, and the enamel remineralizes. If you experience persistent sensitivity or discomfort, it is recommended to discontinue use and consult with a dental professional.

2. Gum Irritation:

In some cases, the peroxide gel present on the dissolving strips might come into contact with the gums, causing temporary irritation. To minimize this risk, it is crucial to follow the application instructions carefully and ensure that the strip is placed only on the surface of the teeth. If gum irritation persists or worsens, it is advisable to seek advice from a dentist.

3. Insufficient Results for Severe Stains:

As mentioned earlier, dissolving whitening strips may not provide satisfactory results for severe intrinsic stains. These types of stains usually require more robust professional treatments such as veneers or dental bonding. Moreover, if you have dental restorations, such as crowns or veneers, whitening strips might not be effective in whitening these artificial surfaces.


Dissolving whitening strips can be an effective and convenient method for achieving a brighter smile. However, the extent of their success depends on various factors such as oral hygiene, stain severity, and the consistency of use. While these strips can yield noticeable results for mild to moderate stains and are generally safe for most individuals, it's advised to consult with a dentist or oral care professional before beginning any whitening treatment to ensure it is suitable for your specific needs. With proper usage and realistic expectations, dissolving whitening strips can help you achieve the radiant smile you desire.
