What is the direct answer?

Yes, peroxide whitening can cause temporary tooth sensitivity by moving through enamel and dentin toward the nerve.

What does this question mean?

Sensitivity is more likely to be noticed when enamel is thin, dentin or root surfaces are exposed, teeth are cracked, or decay and worn areas are present. Concentration, contact time, frequency, and tray fit also affect exposure.

What can you do next?

Use the product only as instructed and do not extend the wear time or add extra gel. A dentist may modify the schedule, check the tray fit, treat exposed root surfaces, or recommend a desensitising product containing fluoride or potassium salts.

When should you seek dental care?

Arrange dental care if sensitivity is severe, lasts after whitening has stopped, affects one tooth, or occurs with spontaneous pain. Pain from decay, a crack, or pulp inflammation needs a different treatment.

What should you ask the dentist?

Ask what is causing your sensitivity and whether whitening should pause. Ask which gel strength, wear schedule, and desensitising approach fit your teeth.
