Sensitivity is one of the most common questions patients ask before whitening their teeth. Between circulating experiences and inaccurate information, many people hesitate to take the step. Here is what you should know.
Is sensitivity after whitening common?
Some patients may experience temporary sensitivity during or after the whitening period, especially to cold. Its intensity varies from person to person, and it usually subsides within a short time.
Common Misconceptions
- “Whitening weakens the teeth”: Professional whitening performed according to the dentist's and manufacturer's instructions is not intended to affect tooth structure, and temporary sensitivity does not mean permanent damage.
- “Anyone with sensitivity cannot whiten”: Not necessarily. The dentist assesses the case and may choose suitable settings or a suitable protocol; some systems, such as the fläsh lamp, include dedicated settings for sensitive teeth.
- “Over-the-counter products are gentler on the teeth”: The absence of examination and follow-up can make inappropriate use more uncomfortable, not less.
How to reduce sensitivity
- Tell your dentist in advance if you suffer from tooth sensitivity.
- Follow your dentist's instructions for the take-home system regarding duration and frequency of use.
- Ask your dentist about suitable care products before and after whitening.
- Avoid very cold or very hot drinks in the first days if you feel sensitivity.
When to see your dentist
If sensitivity lasts longer than expected or is severe, see your dentist to assess the case.
