Ada approved teeth whitening
Look for a recognized dental product seal and clear peroxide labeling, then have a dentist check decay, gums, and restorations before whitening.
The short answer
A whitening product may be evaluated through a dental association seal or other recognized product review program, but the label is not a substitute for an oral examination. Whitening uses peroxide to break down stain in natural enamel and dentin.
What should a dentist check before you whiten your teeth?
A dentist first checks for cavities, cracks, gum inflammation, exposed roots, and restorations. The examination matters because whitening can irritate inflamed tissues and cannot change the shade of composite, porcelain, metal, or denture teeth.
How can you compare different whitening products safely?
Compare the active ingredient, concentration, contact time, application method, and directions. Use only as labeled, protect the gums from gel, and stop for persistent sensitivity or burning.
When should you delay whitening and see a dentist first?
Seek dental care before whitening if you have toothache, bleeding gums, ulcers, a dark single tooth, or extensive restorations. Professional whitening or custom trays may be selected after diagnosis.
What should you ask about product approval and final shade?
Ask what the product review mark covers, whether your teeth and gums are ready, and how existing restorations will affect the final shade.
