Why does Teeth Whitening Cause Sensitivity?

Tooth Sensitivity: Teeth whitening products, especially those containing peroxide-based bleaching agents, can penetrate the enamel and reach the dentin layer beneath. Dentin contains tiny tubules that lead to the nerve of the tooth. If the dentin is exposed or if the tubules are more permeable, it can lead to increased tooth sensitivity.

Concentration of Whitening Agents: Professional teeth whitening procedures often use higher concentrations of whitening agents, which can increase the likelihood of sensitivity. Over-the-counter products may also contribute to sensitivity, especially if they are not used as directed.

Pre-existing Dental Conditions: Individuals with existing dental conditions, such as cavities, cracked teeth, or gum recession, may be more prone to experiencing pain or sensitivity during teeth whitening.

Incorrect Application: If a teeth whitening product is not applied correctly or if the tray used for at-home whitening does not fit properly, it can lead to uneven distribution of the whitening agent, increasing the risk of sensitivity.

Overuse of Whitening Products: Using teeth whitening products too frequently or for an extended period can contribute to increased sensitivity. It's essential to follow the recommended guidelines provided by the dentist or on the product packaging.

Gum Irritation: Whitening products that come into contact with the gums can cause irritation and discomfort. This is more common with over-the-counter whitening strips or gels that may not have a customized application.
