Professional, in-office teeth whitening is one of the fastest and most effective ways to brighten your smile. While the results are immediate and stunning, its normal to experience temporary tooth sensitivity after whitening. This sensitivity typically occurs when the whitening agents penetrate the enamel to remove stains, slightly exposing the dentin beneath.
At McLevin Dental Clinic, we want your whitening experience to be comfortable from start to finish. This guide shares practical, dentist-approved tips for relieving tooth sensitivity after in-office teeth whitening, so you can enjoy your brighter smile without discomfort.
Why Does Sensitivity Occur After Teeth Whitening?
During whitening, powerful agents like hydrogen peroxide open enamel pores to lift stains. This temporarily exposes the dentin layer, which contains tiny nerve endings connected to your tooths nerve center.
Common sensations include:
Sharp zaps of pain when exposed to cold, hot, or sweet foods.
Generalized aching in the teeth for 24 to 72 hours.
This sensitivity is normal and should gradually subside within a few days.
How Long Does Sensitivity Last?
Mild sensitivity: Usually fades within 2448 hours.
More noticeable discomfort: Can last up to 72 hours but continues improving.
Sensitivity beyond 45 days is uncommon and may warrant a call to McLevin Dental Clinic.
Effective Tips to Relieve Sensitivity Post Whitening
1. Use a Desensitizing Toothpaste Immediately
Brands like Sensodyne, Pronamel, or Colgate Sensitive are designed to block pain signals from the nerves.
Start using a desensitizing toothpaste 1 week before whitening and continue for at least 1 week afterward.
2. Avoid Extreme Temperatures
Skip very cold drinks (ice water, smoothies) and very hot beverages (coffee, tea) for 48 hours.
Stick to room temperature or lukewarm foods and drinks.
3. Brush Gently with a Soft-Bristled Toothbrush
Use light pressure to avoid irritating already sensitive enamel.
Avoid abrasive whitening toothpaste during this period, as it can worsen sensitivity.
4. Use Fluoride Mouth Rinses or Gel
A fluoride rinse or gel helps strengthen enamel and reduce sensitivity quickly.
Your dentist at McLevin Dental Clinic may recommend a professional fluoride treatment during or after whitening.
5. Avoid Acidic and Sugary Foods Temporarily
Limit citrus fruits, vinegar-based foods, carbonated drinks, and candies for 23 days.
Acid weakens enamel further, while sugar promotes bacteria that may exacerbate discomfort.
6. Take Over-the-Counter Pain Relievers if Needed
Use ibuprofen or acetaminophen according to the label to reduce discomfort if sensitivity becomes bothersome.
7. Consider Remineralizing Products
Products containing calcium phosphate or hydroxyapatite help seal the enamel pores more quickly.
Ask McLevin Dental Clinic for recommendations on effective remineralizing gels.
8. Limit Whitening Sessions
Space out future whitening treatments if needed to reduce cumulative sensitivity.
Discuss a customized whitening plan with your dentist to balance effectiveness with comfort.
Foods That Are Sensitivity-Friendly After Whitening
Mashed potatoes, yogurt, oatmeal, pasta, scrambled eggs, soft fruits like bananas, and lukewarm soups.
Avoid biting directly into cold fruits or drinking ice-cold beverages.
What to Avoid Right After Whitening
Dark-staining foods and beverages: Coffee, tea, red wine, soy sauce, tomato sauce.
The enamels pores are temporarily open, making teeth more prone to new stains.
Avoid for at least 2448 hours.
