Best way to whiten your teeth safely

Tooth whitening uses peroxide chemistry to break down some color molecules within enamel and dentin; it does not remove fillings, crowns, or veneers. The relevant anatomy or material determines which treatment can address the problem.

Surface stains and internal tooth color require different approaches. Custom trays keep whitening gel positioned against the teeth. Temporary sensitivity or gum irritation can occur and depends on the product and use. Arrange an examination so the plan is based on the actual findings.

Seek dental care when symptoms persist, worsen, interfere with eating or sleep, or involve swelling, spontaneous bleeding, fever, trauma, or a change that does not settle.

Will whitening change a crown? Whitening changes natural tooth color, not the shade of existing crowns, veneers, or fillings. How should I prepare for whitening? A dentist should check for decay, cracks, gum inflammation, and exposed root surfaces before treatment.
