Teeth whitening is a safe and effective way to brighten your smile. Whether youve had professional in-office whitening or used take-home kits from McLevin Dental, its common to experience some degree of tooth sensitivity afterward. While this sensitivity is temporary, knowing how to manage it is key to enjoying your stunning new smile comfortably.
Our Scarborough dental team has put together this simple guide on managing tooth sensitivity post whitening, helping you feel at ease after your whitening treatment.
Why Does Tooth Sensitivity Happen After Whitening?
Teeth whitening products contain peroxide-based agents that penetrate enamel to remove deep stains. This temporarily opens microscopic pores in the enamel, exposing the dentin layer where nerves reside. As a result, your teeth may feel more sensitive to:
Hot or cold drinks
Sweet or acidic foods
Even air exposure in some cases
This sensitivity usually lasts anywhere from a few hours to a few days.
Best Tips for Managing Tooth Sensitivity After Whitening
1. Switch to Sensitive Toothpaste
Use toothpaste designed for sensitive teeth, like Sensodyne or Colgate Sensitive.
These products help block nerve signals to reduce discomfort.
2. Avoid Extreme Temperatures
Skip very hot coffee, tea, or icy drinks for 2448 hours after whitening.
Opt for lukewarm beverages instead.
3. Use a Soft-Bristled Toothbrush
Brush gently using a soft toothbrush to avoid further irritating the enamel.
4. Rinse With Fluoride or Saltwater
Use a fluoride rinse to help strengthen enamel.
Alternatively, rinse with ½ teaspoon salt in one cup of warm water to soothe sensitive gums and teeth.
5. Eat Tooth-Friendly Foods
Stick to soft, non-acidic, and non-crunchy foods like yogurt, scrambled eggs, mashed potatoes, and bananas.
Avoid acidic foods (citrus, vinegar), sweets, and spicy items until sensitivity subsides.
6. Avoid Whitening Toothpaste Temporarily
Whitening toothpastes are abrasive and may worsen sensitivity immediately after treatment.
Switch back to them only once discomfort fades.
How Long Does Sensitivity Last After Whitening?
Mild cases: Sensitivity fades within 2448 hours.
Moderate cases: May last up to 34 days depending on the individual.
If sensitivity persists beyond a week, consult McLevin Dental to rule out underlying issues.
How to Prevent Future Whitening Sensitivity
Ask about desensitizing treatments before your whitening session.
Use fluoride trays or gels before and after whitening to strengthen enamel.
Space out whitening sessionsavoid back-to-back treatments.
Use a lower-concentration whitening formula if youre prone to sensitivity.
