Teeth whitening is one of the most popular cosmetic dental treatments to enhance your smiles brightness and confidence. Whether youve chosen an in-office whitening treatment or take-home whitening trays, its common to experience temporary tooth sensitivity afterwardespecially to cold, heat, or sweet foods.
At McLevin Dental Clinic, our goal is not only to deliver dazzling whitening results but also to ensure your comfort during and after the process. This guide shares the best practices for reducing tooth sensitivity after whitening procedures, so you can enjoy a radiant smile without discomfort.
Why Does Tooth Sensitivity Happen After Whitening?
Temporary enamel dehydration: Whitening gels open the microscopic pores in your teeth, which temporarily increases exposure to external stimuli.
Nerve irritation: Peroxide-based agents penetrate the enamel and may irritate the dentin layer close to the tooths nerve.
This sensitivity typically lasts 24 to 72 hours, then diminishes as the enamel rehydrates.
How Long Does Whitening Sensitivity Last?
Most sensitivity resolves within 13 days after treatment.
Rarely, mild lingering sensitivity can last up to a week, depending on tooth structure and individual response.
Effective Ways to Reduce Tooth Sensitivity After Whitening
1. Use Desensitizing Toothpaste
Brands like Sensodyne, Pronamel, or Colgate Sensitive help block pain signals from the tooth surface to the nerve.
Start using desensitizing toothpaste before whitening and continue for at least one week after.
2. Avoid Hot and Cold Foods Temporarily
Avoid items like:
Ice water
Hot coffee or tea
Ice cream or frozen treats
Stick to room-temperature or lukewarm foods and drinks for 4872 hours post-whitening.
3. Avoid Acidic or Sugary Foods
Limit exposure to:
Citrus fruits
Vinegar-based foods
Soft drinks
Wine
These substances can worsen enamel sensitivity immediately after whitening.
4. Apply Fluoride Gel or Remineralizing Products
Use fluoride rinses or gels recommended by your dentist to help strengthen enamel and reduce sensitivity.
Remineralizing products like calcium phosphate-based creams can help close enamel pores more quickly.
5. Brush Gently with a Soft-Bristled Toothbrush
Use light pressure and avoid aggressive brushing, especially near the gumline, to prevent irritation.
6. Chew on the Opposite Side (if localized sensitivity)
If only a few teeth are sensitive, chew on the side that feels more comfortable temporarily.
7. Stay Hydrated
Drink plenty of water to help rehydrate the enamel and flush out residual whitening agents.
8. Consider Shorter Whitening Sessions Next Time
If sensitivity is severe or consistent:
Ask McLevin Dental Clinic about adjusting the concentration or duration of future whitening sessions.
Take longer breaks between whitening treatments to allow your teeth to recover fully.
