The Ultimate Guide to Teeth Sensitivity After Whitening


Teeth whitening is a sought-after cosmetic procedure that promises a radiant smile. However, teeth sensitivity after whitening is a common concern that many face. At Levantine Dental Clinic in Dubai, we understand this issue and are committed to providing expert insights and solutions. This guide explores the causes, symptoms, and remedies for teeth sensitivity after whitening, tailored to your needs.

Teeth Sensitivity After Whitening: An Overview

What is Teeth Sensitivity?

Teeth sensitivity, or dentin hypersensitivity, is a condition that can cause discomfort or sharp pain when consuming certain foods and drinks. It’s a concern that we at Levantine Dental Clinic often address with our patients.

Causes of Teeth Sensitivity After Whitening

At Levantine Dental Clinic, we’ve identified several factors that contribute to sensitivity after whitening:

  • Chemical Exposure: Whitening agents may irritate the nerves.
  • Overuse of Whitening Products: Excessive use can worsen sensitivity.
  • Pre-existing Dental Conditions: Existing dental issues may increase sensitivity.

The Science Behind Teeth Whitening

Teeth whitening is a popular dental procedure that helps to brighten the color of your teeth by removing stains and discoloration. The science behind teeth whitening lies in the use of whitening agents, typically peroxide-based, which penetrate the enamel to reach discolored molecules within the teeth. However, this process can sometimes lead to teeth sensitivity. 

Common Symptoms and Signs of Teeth Sensitivity

Teeth sensitivity, also known as dentin hypersensitivity, is a common dental problem experienced by many individuals, particularly after teeth whitening procedures. This condition manifests through varying symptoms and signals that dental professionals often use to diagnose and address the issue appropriately. Understanding these symptoms can equip individuals with the necessary knowledge to seek prompt professional help and employ effective solutions. 

Physical Symptoms 

Physical symptoms of teeth sensitivity often involve discomfort or pain in response to certain triggers. The following are some common physical symptoms: 

  • Sharp, sudden pain: This is often the first sign of teeth sensitivity. The affected individual may experience a sharp, sudden, and often brief pain that occurs when eating or drinking hot, cold, sweet, or very acidic foods and drinks.
  • Prolonged toothache: Some individuals may experience a prolonged toothache that persists even in the absence of any apparent triggers. This typically indicates a more severe case of teeth sensitivity.
  • Discomfort during brushing or flossing: If normal oral hygiene practices like brushing or flossing cause discomfort or pain, it can be a sign of teeth sensitivity.
  • Receding gums: Receding gums often expose the dentin layer of the tooth, which is more sensitive than the external enamel. This can lead to increased teeth sensitivity.

Behavioral Signs 

In addition to physical symptoms, there are also behavioral signs that can indicate teeth sensitivity. These signs are often subtle but can provide valuable clues about the individual’s dental health status: 

  • Avoidance of certain foods or drinks: If an individual starts avoiding hot, cold, sweet, or acidic foods and drinks due to the pain or discomfort they cause, it’s a clear sign of teeth sensitivity.
  • Changes in eating habits: Changes in how or what an individual eats, such as shifting food to the less sensitive side of the mouth, can be a behavioral sign of teeth sensitivity.
  • Avoidance of oral hygiene practices: If an individual avoids or reduces brushing or flossing due to the discomfort these activities cause, it’s a strong indicator of teeth sensitivity.

Note: Even though these symptoms and signs can strongly suggest teeth sensitivity, it is always advisable to seek a professional dental evaluation. Other dental problems can also cause similar symptoms, and only a dental professional can definitively diagnose the issue.

By recognizing these symptoms and signs, individuals can ensure they take timely and effective measures to address teeth sensitivity, particularly after teeth whitening procedures. This can significantly improve their overall dental health and quality of life.

Preventing Teeth Sensitivity After Whitening

Teeth sensitivity following whitening procedures is a common concern for many individuals. The process of whitening can sometimes lead to temporary sensitivity, due to the penetration of peroxide into the tooth’s enamel and dentin, reaching the nerves and cells inside. This sensitivity is usually temporary, diminishing over several days to one or two weeks. However, there are steps that can be taken to prevent or minimize this discomfort. 

Preventive measures can be categorized into two main groups, those implemented before the whitening procedure and those that are recommended post-procedure. Both sets of measures are critical and contribute equally to managing post-whitening teeth sensitivity. They ensure that individuals can maintain the brightness of their smile while also protecting their oral health. Following these guidelines closely can significantly reduce the likelihood of experiencing discomfort after teeth whitening.

Choose the Right Whitening Method

Levantine Dental Clinic offers professional whitening services that minimize sensitivity.However, some patients may still experience post-treatment sensitivity. This sensitivity is typically a transient effect, and there are several effective strategies to manage it. Understanding the cause of this discomfort is the first step toward finding a solution. Often, teeth sensitivity after whitening is due to the whitening agent penetrating the enamel and reaching the nerves in the dentin. This can cause a temporary increase in sensitivity to hot and cold temperatures, as well as sweet or acidic foods and drinks.  

Follow Instructions Carefully

Our team provides clear guidelines to prevent overuse and subsequent sensitivity.These guidelines are especially useful for those who have undergone teeth whitening procedures and are experiencing sensitivity afterward. The condition, known as dentinal hypersensitivity, arises when the dentin – the layer beneath the tooth’s enamel – is exposed due to the whitening process. The dental clinic’s team is well-versed in understanding and treating this issue, providing ten effective solutions to manage and alleviate this discomfort.

Consider Pre-treatment with Desensitizing Products

We recommend specific products to reduce sensitivity before whitening.For instance, the dental clinic often suggests using toothpaste specially formulated for sensitive teeth. Such toothpaste contains ingredients like potassium nitrate or strontium chloride, which can help block the transmission of pain signals from the surface of your tooth to the nerve inside. In addition, incorporating a fluoride rinse into your daily oral care routine can also strengthen tooth enamel and reduce pain. It’s crucial to begin using these products at least two weeks prior to the whitening procedure to maximize their efficacy.

There are instances, though, when professional attention at Levantine Dental Clinic is necessary. The following situations signal that it’s time to visit a dental professional: 

  • Chronic Pain: If your teeth sensitivity lasts for more than a few days post-whitening, it’s a clear sign that a dental visit is in order.
