How much hydrogen peroxide in spotlight teeth whitening strips

Whitening strips are flexible polymer carriers coated with gel that may contain hydrogen peroxide or a peroxide-releasing compound such as carbamide peroxide. The clinically relevant exposure depends on the stated active ingredient, its concentration, the gel mass, strip contact time, and how well the strip fits the teeth and gums.

Identify the exact Spotlight product, read its current ingredient panel and directions, and do not transfer instructions from another strip version. Before use, have a dentist check cavities, cracks, gum recession, restorations, and sensitivity; they can explain whether the product fits your teeth and what alternatives exist if it does not.

Ask for dental advice before use if you have pain, untreated decay, gum disease, ulcers, enamel defects, or extensive restorations. Stop and seek advice for severe sensitivity, burning, swelling, or tissue injury.

Ask how the exact product names its active peroxide, whether its label gives a concentration or total amount, how long the strip contacts teeth, and whether your restorations will match afterward.
