How can you whiten sensitive teeth with less irritation?

Whitening with sensitive teeth starts with finding the cause of sensitivity and using a dentist-directed, lower-irritation plan.

Why can exposed dentine make whitening uncomfortable?

Sensitivity occurs when exposed dentine allows fluid movement in microscopic tubules toward the pulp, often after enamel wear, gum recession, a crack, decay, or recent dental treatment. Peroxide whitening can temporarily increase this response.

What should you do before whitening sensitive teeth?

Have the teeth examined before whitening, treat decay or gum disease, use a desensitizing product if advised, and follow the exact contact time and concentration for the chosen system. Stop and report sharp or lingering pain.

Which symptoms mean whitening should be delayed?

Delay whitening and seek care for spontaneous pain, one-tooth sensitivity, pain on biting, a visible crack, swelling, or sensitivity that persists after the product is stopped.

What whitening plan could limit contact with your gums?

What is causing my sensitivity, should it be treated first, and which whitening concentration, tray fit, and schedule will limit contact with my gums?
