Achieving a brighter smile through teeth whitening has become increasingly popular. However, a common side effect is temporary tooth sensitivity to hot or cold. This sensitivity is usually mild and subsides after treatment. If you already have sensitive teeth, you’ll need to choose your whitening method carefully.
Several whitening methods exist. Tray systems use a custom-fitted tray to hold the whitening agent against your teeth. Whitening strips, thin plastic strips with the whitening agent, adhere directly to your teeth. Gels containing the whitening agent are also available; their thick consistency allows them to stay on your teeth until wiped off.
The increased sensitivity is due to carbamide peroxide or hydrogen peroxide, the main ingredients in most tooth whitening products. These compounds are forms of bleach, so “tooth whitening” and “tooth bleaching” are often used interchangeably. If your product contains either, consider these steps to reduce thermal sensitivity:
* **Reduce Treatment Time:** Shorten the duration the whitening product stays on your teeth. If the instructions say two hours, try one hour.
* **Increase Time Between Treatments:** If the usual frequency is daily, try every other day. If discomfort persists, combine both methods – shorter treatment times and less frequent applications.
Even those without initial sensitivity may experience temporary discomfort. Brush before and after treatment with toothpaste designed for sensitive teeth. These toothpastes often contain fluoride to desensitize your teeth. Discuss your whitening plans with your dentist; they may offer a professional fluoride treatment for home use.
If tooth whiteners prove too uncomfortable, consider whitening toothpastes. These clean teeth with mild abrasives instead of bleach, minimizing sensitivity, though the whitening effect is less dramatic.
Whitening with sensitive teeth may require extra time and care, but you can still achieve a brighter smile.
