Why do my teeth hurt after white strips?


Using white strips for teeth whitening has become a popular and convenient option for many people. However, some individuals experience tooth sensitivity or pain after using these strips. This article will explore the reasons behind why teeth might hurt after using white strips and provide useful tips to alleviate the discomfort.

Understanding Teeth Sensitivity

Teeth sensitivity is a common issue experienced by many individuals, even in the absence of teeth whitening treatments. When the protective layer of enamel wears down over time or recedes from the gums, the underlying dentin becomes exposed. Dentin consists of microscopic tubules that connect to the nerve endings of teeth, making them sensitive to various external stimuli.

Why White Strips Cause Tooth Sensitivity

1. Temporary Increase in Tooth Sensitivity

Using white strips typically involves applying peroxide-based bleaching agents to the teeth. These agents penetrate the enamel and initiate a chemical reaction that breaks down stain molecules, making the teeth appear whiter. During this process, the peroxide can momentarily irritate and increase the sensitivity of the tooth nerves. This heightened sensitivity may cause discomfort, especially when consuming cold or hot beverages or food items.

2. Gum Irritation

Another reason for tooth pain after using white strips may be related to gum irritation. Strips that are not properly aligned or do not adhere evenly to the teeth can cause the bleaching agent to come into contact with the gums. This can lead to gum sensitivity, inflammation, and discomfort.

3. Overuse of White Strips

Overusing white strips is a common mistake made by individuals who desire exceptionally fast results. However, using these strips too frequently can damage the tooth enamel and exacerbate tooth sensitivity. It is crucial to follow the instructions provided by the manufacturer and consult a dental professional if any concerns arise.

4. Pre-existing Dental Conditions

Individuals with pre-existing dental conditions, such as cavities, gum disease, or cracked teeth, may experience heightened sensitivity or pain after using white strips. These conditions can make teeth more susceptible to discomfort as the bleaching agents penetrate the enamel. It is crucial to address these pre-existing conditions before utilizing any teeth whitening methods.

Alleviating Tooth Discomfort

1. Sensitivity Toothpaste

Using a toothpaste specifically formulated for sensitive teeth can provide relief after using white strips. These toothpastes contain compounds such as potassium nitrate or strontium chloride, which help to reduce nerve sensitivity and alleviate discomfort. Consistently using sensitivity toothpaste can gradually desensitize the nerves and minimize tooth sensitivity over time.

2. Limiting White Strip Usage

Moderating the use of white strips can help reduce tooth sensitivity and minimize discomfort. Adhering strictly to the manufacturer's instructions regarding duration and frequency of use is important. Avoiding overuse and allowing ample time between treatments can give the teeth and gums a chance to recover, reducing the likelihood of sensitivity.

3. Proper Strip Application

To prevent gum irritation and minimize discomfort, it is essential to properly apply white strips. Ensure that the strips are evenly placed and do not extend onto the gums. Following the manufacturer's instructions on aligning the strips properly will help ensure an effective yet safe application.

4. Consulting a Dental Professional

If persistent tooth sensitivity or pain occurs after using white strips, it is advisable to consult with a dental professional. They can evaluate the overall oral health, identify the underlying cause of sensitivity, and provide targeted treatment or advice to alleviate discomfort.

5. Alternative Teeth Whitening Methods

For individuals who experience severe tooth sensitivity or unbearable pain after using white strips, it may be beneficial to consider alternative teeth whitening methods. Professional dental whitening treatments, such as laser whitening or custom-fitted trays, can provide effective results while minimizing tooth sensitivity.


Teeth sensitivity after using white strips is a common occurrence. Understanding the causes of this sensitivity and following the recommended practices can help alleviate discomfort and ensure a positive teeth whitening experience. By using sensitivity toothpaste, properly applying white strips, moderating usage, and seeking professional advice when necessary, individuals can enjoy the benefits of whiter teeth without enduring unnecessary pain. Remember, maintaining good oral hygiene and treating any pre-existing dental issues are essential for healthy teeth and gums.
