Carbamide peroxide and hydrogen peroxide are two of the most commonly used whitening agents in dental procedures. One of the most popular hydrogen peroxide-based products is Opalescence Boost, which contains a gel with 38% hydrogen peroxide. This is what whitens and brightens teeth. Additionally, potassium nitrate is applied to strengthen tooth enamel, reduce sensitivity, and protect against tooth decay.
Household teeth whitening systems contain 3-20% peroxide (carbamide or hydrogen peroxides), while office systems contain 15-43% peroxide. NiteWhite is a clinical-grade teeth whitening gel with 22% carbamide peroxide, making it an excellent choice for those with some tooth sensitivity. Colgate Optic White toothpaste also whitens teeth, and it combines ACP (amorphous calcium phosphate) with potassium nitrate and fluoride to improve whitening results and minimize sensitivity. To prevent overuse of whitening products, it's important to keep your teeth as white as possible after professional whitening.
If you choose to whiten your teeth at home, it's best to consult your dentist before you start and to follow the instructions that come with the product. Generally, drugstore teeth whiteners can be used for 14 consecutive days, but this will depend on individual sensitivity. In-office teeth whitening requires skill to avoid injury to the gingival area (gum). Professional teeth whitening is expensive and inaccessible for many people, so Crest produces one of the best (if not the best) teeth whitening products for the home.
Lasers can also be used to safely and efficiently whiten teeth. Colgate's Optic White advanced LED whitening system promises to make your teeth six shades whiter with blue LED technology. Tom's of Maine Simply White toothpaste uses “naturally occurring silica” to remove surface stains.
