What is the direct answer?

Whitening can cause brief tooth sensitivity or gum irritation when peroxide reaches dentine or contacts the gingiva.

What does this question mean?

Peroxide can trigger sensitivity through dentinal tubules; poor tray fit, exposed roots, cracks, decay, or inflamed gums can intensify symptoms.

What can you do next?

Follow the instructions and stop if burning or sharp pain develops. A dentist can check the teeth, gums, and tray fit before adjusting the plan.

When should you seek dental care?

Contact a dentist if pain is severe, persists, affects one tooth, or comes with swelling or a defect.

What should you ask the dentist?

Ask whether the pain comes from gel exposure, tray fit, recession, decay, or a crack, and whether restorations will change colour.

Frequently asked questions

What is the usual first step?
