Can peroxide whitening make your teeth sensitive?
Yes, peroxide whitening can cause temporary tooth sensitivity by moving through enamel and dentin toward the nerve.
Why can some teeth react more strongly to peroxide?
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.
How should you use peroxide whitening safely?
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 sensitivity after whitening be checked?
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 about your whitening sensitivity?
Ask what is causing your sensitivity and whether whitening should pause. Ask which gel strength, wear schedule, and desensitising approach fit your teeth.
