Can peroxide whitening harm your teeth or gums?

Peroxide whitening can cause tooth sensitivity or gum irritation, and the risks depend on the product, concentration, contact time, and your oral health.

How does peroxide whitening change tooth colour?

Hydrogen peroxide and carbamide peroxide can break down stain molecules within enamel and dentin, but they do not whiten fillings, crowns, veneers, or implants.

What should you check before choosing peroxide whitening?

Do not apply household peroxide or mix whitening products; have decay, cracks, gum inflammation, and existing restorations checked before choosing a method.

Which reactions mean you should stop peroxide whitening?

Stop the product and seek dental advice for marked burning, persistent pain, ulceration, or worsening sensitivity.

What should you ask about peroxide and restorations?

Ask which peroxide formulation is intended for teeth, how it will contact the gums, and whether your restorations or enamel defects change the plan.

Frequently asked questions

Can this problem improve without treatment?

That depends on the cause and the tissues involved; an examination distinguishes a temporary irritation from a condition needing treatment.

What will the dentist examine?

The dentist will inspect the relevant tooth, gums, bite, and nearby oral tissues, adding tests or imaging when the findings call for them.
