Whitening Strips Can Kill The Collagens

The latest study reveals that whitening products can bring a shine but can possess multiple threats to the health of your teeth.

If you are prone to the utilization of teeth whitening products, make sure that you are well aware of their harmful effects on your teeth. The latest study reveals that whitening products can bring a shine but can possess multiple threats to the health of your teeth.

Americans are people who are very particular about the health of their teeth. They love to transform their teeth into pearly white colour and they are ready to spend millions of dollars to give a shiny feature to their teeth.

Recent research presented at the American Society for Biochemistry and Molecular Biology meeting in Orlando and Florida highlights the fact that how hydrogen peroxide (a part of the whitening products) can damage your teeth to a large extent. It specifically damages the dentin layer (rich in proteins) that lies underneath the enamel of your teeth.

The research revealed a huge amount of protein loss due to the wide use of such whitening products. According to Kelly Keenan, PhD, leading author of the study and an associate professor of chemistry at Stockton University (New Jersey) reveals, “We measured the amount of collagen (an essential protein found in dentin) in two different ways and found a huge significant loss”. Keenan’s team decided to find out how dentin is fragmented into small pieces by hydrogen peroxide. 

Whitening Products Causes Damage To Teeth

Keenan’s team executed three studies on how the whitening element present in the teeth whiteners and whitening strips can affect the dentin. Our teeth are composed of three separate layers – outer protective tooth enamel, dentin, and connective tissues.

Dentin layer – It consists of proteins such as collagen; Connective Tissues – Binds the roots to gum

Hydrogen Peroxide

According to a statement given by John Grbic, DMD and a practising dentist and professor at the Columbia University Medical Center said that it is a difficult process to eliminate hydrogen peroxide while whitening your teeth. It is considered to be a major ingredient in the process of teeth whitening. He also revealed that people who undergo teeth whitening (with hydrogen peroxide) experience high sensitivity later on.

The presence of hydrogen peroxide oxidizes the dentin layer, more than affecting the enamel region. Hydrogen peroxide can maximize the damage done to the teeth along with sensitivity. Generally, the teeth whitening products including the whitening strips comprise nearly 25% of the hydrogen peroxide level. 

The most predominant kinds of whitening strips carry around 14% of the bleaching agent whereas the milder version of the product contains around 6%. Sensitivity to such products varies from one person to another.

Most people include teeth whitening rinses but long-term use of these rinses can affect the flora or the bacteria present in your mouth. Grbic states that after the process of teeth whitening using hydrogen peroxide, he gives away a tray of fluoride to his patients. Fluoride helps to recreate the structure of the internal tooth and reduce or eliminate the occurrence of insensitivity.


Keenan wants to focus on how collagen's presence in dentin can repair itself and what kind of damage can be created by hydrogen peroxide. Whereas Grbic, on the other hand, states that people who try out teeth whitening at home should include the use of fluoride. For example, use of the fluoride comprises toothpaste.

Using hydrogen peroxide won’t perform magic, especially on teeth that come with dark fillings. Even today, there are numerous kinds of myths and misconceptions associated with the process of teeth whitening. Remember always to keep your teeth strong and healthy with the right kind of dental approach.
