Teeth Whitening Strips

Choose based on sensitivity level, desired whitening strength, and treatment duration: look for lower peroxide concentrations or 'sensitivity' formulas if you have tooth/gum sensitivity, stronger formulas for faster results, and product directions that match how often you can apply strips (daily vs. weekly)

Many strips offer low-peroxide or sensitivity-specific formulas that reduce irritation, but whitening strips do not whiten crowns, veneers, or fillings; consult your dentist before use if you have extensive dental work or severe sensitivity

Visible improvement often appears within several days to two weeks depending on formula strength and frequency; maintenance depends on diet and oral hygiene, with touch-up treatments typically needed every few months to maintain results

Check for active whitening agents (hydrogen peroxide or carbamide peroxide) and their concentration range, clear application time per use, total number of applications in the package, and any warnings about use with braces, restorations, or gum irritation

Follow the product’s recommended wear time, avoid overlapping strips onto gums, use products designed for sensitivity, rinse and discontinue use if severe irritation occurs, and consider using desensitizing toothpaste before and after treatments

Lower-cost strips typically offer fewer applications or lower peroxide concentrations, so they may take longer to show results; compare cost per treatment and average ratings to judge value rather than just sticker price

Store unopened strips in a cool, dry place away from direct heat; dispose of used strips in regular household waste following local guidelines, and do not reuse strips once removed from the mouth
