Pain relief for sensitive teeth after whitening
Whitening sensitivity is usually managed by pausing the product, avoiding triggers, and using desensitising toothpaste as directed.
The short answer
Whitening sensitivity is usually managed by pausing the product, avoiding triggers, and using desensitising toothpaste as directed. The cause determines the appropriate clinical step.
Why can peroxide cause sharp sensitivity after whitening?
Peroxide can irritate dentinal tubules and cause a short sharp response to cold or air. Decay, cracks, worn enamel, or exposed roots can cause a different pattern.
What should you do immediately after whitening sensitivity?
Pause whitening, use a desensitising toothpaste, and choose lukewarm food and drinks. Do not exceed the product contact time or apply concentrated peroxide to gums.
When does whitening sensitivity need a dentist?
See a dentist if pain is severe, localized, spontaneous, or lingering after cold or heat. Swelling or pain on biting also needs assessment.
When is it safe to resume whitening treatment?
Ask whether the symptoms fit whitening sensitivity and whether the teeth need examination before whitening resumes.
