Can whitening cause tooth sensitivity?

The short answer

Some people experience temporary tooth sensitivity during or after whitening. Discuss your teeth, gums and any previous sensitivity with a dentist before starting.

What to consider for your own care

Ask about your starting shade, existing crowns or fillings, sensitivity and the condition of your gums. Whitening affects natural teeth differently from restorations, so the dentist should review the whole smile.

When to speak with a dentist

If whitening causes persistent sensitivity or irritation, stop and ask the dentist for advice.

Next step

Ask Dental Works: “Can whitening cause tooth sensitivity?” Share your symptoms, goals and any deadline so the dentist can explain suitable options and what should happen next at a Sion East consultation.
