The history of dentistry is comprised of many efforts undertaken to achieve an effective tooth-whitening method. Non-vital tooth bleaching began in 1848 with the use of chloride of lime (Dwinelle, 1850), and in 1864, Truman introduced the most effective technique for bleaching non-vital teeth, a method which used chlorine from a solution of calcium hydrochlorite and acetic acid.
Brushing and flossing are everyday ways to keep your teeth bright, white and healthy. Still, if you might feel like your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone. When the American Academy of Cosmetic Dentistry asked people what they’d most like to improve about their smile, the most common response was whiter teeth. The American Association of Orthodontists also found that nearly 90% of patients requested tooth whitening. A bright smile opens so many doors; It supports self-confidence and makes you look more vital. Many people therefore want beautiful, naturally white teeth. Unfortunately – the enjoyment of coffee, tea, red wine or nicotine can discolor the teeth.
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
