Does Peroxide Make Teeth Sensitive? Understanding the Risks

Many patients ask us about the potential for tooth sensitivity after using peroxide-based whitening products. This article clarifies the link between hydrogen peroxide, a common whitening agent, and increased tooth sensitivity, helping dental professionals advise patients effectively.

How Hydrogen Peroxide Can Affect Teeth

Hydrogen peroxide, while effective at bleaching teeth, can also cause sensitivity. The bleaching process involves penetrating the tooth enamel, slightly demineralizing it. This demineralization exposes microscopic tubules leading to the tooth's nerve, making them more susceptible to stimuli like temperature changes (hot and cold drinks) and even air. The degree of sensitivity depends on factors like the concentration of peroxide, the duration of application, and the individual's pre-existing dental health.

Patient Factors Influencing Sensitivity

Patients with pre-existing conditions such as:

* Receding gums: Exposing the dentin makes them more vulnerable.

* Enamel erosion: Weakened enamel increases susceptibility to sensitivity.

* Existing cavities or cracks: Peroxide can exacerbate these issues.

are more likely to experience increased sensitivity after using peroxide-based whitening treatments.

Minimizing Sensitivity Risks

Several strategies can mitigate sensitivity from peroxide use:

* Lower concentrations: Opt for lower concentrations of hydrogen peroxide when possible.

* Shorter application times: Reduce the duration of application.

* Professional guidance: Recommend professional whitening treatments which are carefully controlled.

* Desensitizing toothpaste: Prescribe desensitizing toothpaste for pre- and post-treatment use.

* Fluoride treatments: Fluoride strengthens enamel.

Proper patient education is crucial for managing expectations and preventing discomfort.

When to Refer Patients

If a patient experiences severe or persistent sensitivity after using peroxide-based whitening products, refer them for a professional evaluation. Underlying dental issues may need addressing.
