Can professional whitening be adapted for sensitive teeth?
Professional whitening can be adapted for sensitive teeth after a dentist checks for decay, cracks, recession, exposed dentine, and other causes.
Why can whitening stimuli cause sensitivity in some teeth?
Sensitivity occurs when stimuli reach dentine tubules or an irritated pulp. Peroxide can temporarily increase this response, while a cavity or crack may be the real source.
What can a dentist change to make whitening more comfortable?
The dentist may treat disease first, use a close-fitting tray, modify gel strength or exposure, protect the gingiva, and schedule applications with pauses.
When should you postpone whitening and seek dental advice?
Postpone whitening while pain is unexplained or lingering after cold. Severe pain, swelling, or spontaneous colour change needs prompt care.
What should you ask about the cause of whitening sensitivity?
Ask what is causing the symptom, which examination or imaging is needed, and which treatment options address that cause.
