why does teeth whitening cause sensitivity

When it comes to teeth whitening products, there are a variety of options available on the market. Many people choose to use these products in an effort to achieve a brighter smile, while others may be looking to remove any unwanted blemishes. However, many people are unaware of the potential side effects associated with teeth whitening treatments.

In this article, we’ll be discussing one particular side effect – sensitivity – and how it can occur after you’ve used a teeth whitening treatment. We’ll also provide some tips on how to avoid this problem in the future.

The Basics of Teeth Whitening

Teeth whitening products can be very irritating to the skin. This is because the ingredients in these products can cause sensitivity in some people. In some cases, teeth whitening products can also cause irritation around the gums.

When using a teeth whitening product, be sure to read the label carefully. If you are experiencing any type of sensitivity, do not use the product. Instead, try another option or consult a doctor.

The Different Types of Teeth Whitening Agents

Whitening products come in different forms and are used by people of all ages, races, and genders. Many people use tooth whitening products to achieve a brighter smile. Tooth whitening agents can be classified into three categories – bleaching agents, lightening agents, and sensitivity agents.

Bleaching agents are the most common type of whitening agent. They remove the surface layer of teeth enamel by breaking down the bonds between molecules. This process can cause sensitivity in some people because it affects the tooth’s natural color. Bleaching agents can be effective if used with caution, as overuse may result in tooth discoloration or even tooth loss.

Lightening agents work by destroying the dark pigment within teeth. Unlike bleaching agents, which use heat or chemicals to break down the enamel, lightening agents use ultraviolent (high-energy) rays to break down the pigment. This process is more likely to cause tooth sensitivity because it affects dentin, which is a soft tissue layer beneath the enamel.

Sensitivity agents are a newer type of whitening agent that was developed specifically to minimize tooth sensitivity. These agents bind to and remove surface stains without breaking down enamel or dentin. Tooth whitening products come in a variety of forms, including gels, pastes, creams, and even toothpastes. It is important to choose a product that is safe for use and is specifically designed to whiten teeth. Some of the most common tooth whitening products include Crest Whitestrips, Listerine PocketGel Whitestrips, Max White Teeth Whitening Toothpaste, Tom’s of Maine White Toothpaste, and Oral-B Professional Care Sensitive Whitestrip Gel.

How Tooth Whitening Causes Sensitivity

Teeth whitening products can cause sensitivity due to the harsh chemicals that are used in the procedure. These chemicals can irritate your skin, which in turn can cause pain, redness, and even swelling. Some people also experience temporary sensitivity to light and sound after undergoing teeth whitening treatment. If you are experiencing any of these symptoms after whitening your teeth, it is best to consult with a doctor to rule out any underlying problems. 


When we whiten our teeth, it is generally because we want them to look their best. However, many people are unaware that a common side-effect of teeth whitening products is sensitivity. While this might not be the most desirable outcome, it can usually be rectified by using toothpaste that doesn’t contain bleaching agents. If you have any questions about tooth whitening or sensitivity in general, please don’t hesitate to reach out to your dental professional.
