Teeth whitening has its roots in the barbershop. In the 17th century, when people sought out the red and white barber pole for a haircut it turns out they were looking for a tooth whitening dental treatment, too. Back then, a barber would file down a patient's teeth with a type of metal file and then dab on a highly corrosive nitric acid to whiten the teeth.
Although the nitric acid worked wonders, it also destroyed tooth enamel. However, a brighter smile seemed to be worth it -- people continued to whiten their teeth this way well into the 18th century.
Fortunately, these days we don't have to go to such lengths to get a whiter smile. In fact, we don't even have to go to the cosmetic dentist for tooth whitening. Take-home whitening dental products such as Crest Whitestrips® offer an effective, yet economical alternative to dentist-administered teeth whitening treatments.
Tooth Whitening Anytime, Anywhere
Is it portable? Is it fast? These are just a couple of 21st century concerns about teeth whitening that Crest Whitestrips resolve. Crest Whitestrips are conveniently packaged to fit into your purse or briefcase.
Wear them on your top and bottom teeth for just 30 minutes a day, twice a day.
Made of a thin, flexible piece of clear plastic, Crest Whitestrips are coated with a safe, but effective amount of peroxide -- the same ingredient used in professional tooth whitening systems.
Because Crest Whitestrips are virtually invisible, you can whiten your teeth discreetly while working, watching TV, reading e-mail or driving in your car.
How to Choose Crest Whitestrips
When it comes to Crest Whitestrips, one size does fit all. However, you can choose from four different types of Crest teeth whitening strips to suit your schedule:

Crest Whitestrips Premium -- See a difference in three days, get full results in seven. Results last a year.

Crest Whitestrips Renewal -- Remove up to 20 years of tooth stains in 10 days. Results last 18 months.
Crest Whitestrips Supreme -- Contains the highest concentration of whitening ingredients. Available only through your dentist.
Tougher tooth stains might require using two Crest Whitestrips tooth whitening kits to get your desired results. Keep in mind that Crest Whitestrips can only whiten natural teeth -- they won't work on dentures or teeth with dental braces, veneers or a dental crown.
Crest Whitestrips are clinically proven and even dentist-recommended; however, it's best to consult with a dentist prior to using any teeth whitening dental product.
