![]() ![]() You can expect to see visible effects after five or more days of twice-daily use, but only expect minimal to moderate whitening results, due to lower levels of bleaching ingredients. Look for pastes that contain hydrogen peroxide if you want noticeable results. "Most conventional whitening toothpastes largely work by using an abrasive called silica to mechanically scrape stains off of teeth, hence the 'whitened' result, not by actual bleaching," explains Justin Rashbaum, D.M.D., a general and cosmetic dentist in New York City for Supersmile. ✔️Whitening toothpaste: Pastes typically contain mild abrasives like hydrated silica, sodium bicarbonate and calcium carbonate to polish and remove surface stains and/or low concentrations of the active teeth whitening ingredient hydrogen peroxide to bleach teeth. Because the ingredients can be diluted or washed away in your mouth over time, the whitening results are generally more moderate. ![]() ![]() Some are left on teeth (even created to be left on overnight), while others are meant to be rinsed off. ✔️Whitening pens or gels: These formulas contain the active teeth lightening ingredient hydrogen peroxide in a pen or gel form that you glide over your teeth to whiten them. Like teeth whitening strips, light devices are very effective because of the amount of time the active ingredient makes full contact with your teeth. ✔️Whitening light devices: A whitening agent is directly applied to teeth then a blue LED light is held over them to increase penetration and accelerate results. If you want to make your teeth white fast or you want to turn yellow teeth white, strips are one of the most effective OTC teeth whiteners, as the active ingredient is left on teeth for an extended period of time. Each session lasts 30 minutes to two hours (follow the directions on the teeth whitening kit's packaging for how to use), so results can be visible in one day, though you'll need up to three weeks of repeated application for full results. ✔️Whitening strips and trays: These kits contain a plastic strip, tray or mold, which is used to apply the bleaching ingredient hydrogen peroxide directly to teeth. Here's a guide to what differentiates each of the options and how they function so you can choose the right form for you, according to the dental experts: There are four main options for teeth whitening at home: whitening strips and trays, LED light devices, pens or gels and toothpastes. "Since the strip wraps around the teeth, the whitening solution has constant contact with teeth, and they’re the easiest to keep in the mouth for the prescribed amount of time." ✔️ Form: As for the best teeth whitener form,"I recommend whitening strips and use them personally," she says. "They're not as effective as peroxide, but are a good natural option that’s gentler on the teeth," Dr. For extremely sensitive teeth, there are also products that don’t contain peroxide, and instead are made with ingredients like aloe vera and coconut oil, which have natural whitening effects that pull stains from the teeth, she says. ✔️ Sensitivity-friendly ingredients: If you have sensitive teeth, "carbamide peroxide is less sensitizing than hydrogen peroxide because it takes more time for the whitening action to occur," Dr. "Don’t focus on the percentage, though, as long as the product contains the active ingredient, which bonds to the stain on teeth and lifts it." ✔️ Active ingredients and potency: For optimal teeth whitening results at home, "look for the active lightening ingredients hydrogen or carbamide peroxide - the maximum percentage is 10% for over-the-counter products," advises Sharon Huang, D.D.S., MICOI, a cosmetic dentist and founder of Les Belles NYC in New York City.
