Achieving a perfect pearly white smile has become an obsession of American people. 63.5% of persons are unhappy with the appearance of their teeth and the color of their teeth is listed as the number reason why they reported the dissatisfaction. Due to this displeasure in their smile appearance, 42.2% of people avoid smiling.
Every year people in United States spend about 2 billion dollars to increase the whiteness of their teeth. Of which, about $280 million is spent on home whitening kits (i.e. Crest white strips, Aquafresh white trays, etc). The American Dental Association (ADA) claim that the number one request of dental patients is to increase the whiteness of their teeth. In addition, the most common type of toothpaste is whitening brands.
Due to this obsession, many people are experiencing moderate sensitivity to extreme pain. About 50% of those surveyed by University of Southern California's School of Dentistry claim that they had moderate sensitivity after having a bleaching treatment. More alarming, 1 in 25 people had extreme severe pain. This pain is described as "pass out on the floor kind of pain." Many fear that bleaching will wear away enamel, but researchers are finding this to be untrue.
To avoid teeth discoloration, people can use these simple techniques that do not involve bleaching chemicals. Brushing and flossing regularly every daily is one prevention mechanism (brushing at least twice a day and flossing at least once). People should avoid drinking beverages such as coffee, tea, and soft drinks which increase teeth staining. If you do so choose to drink these beverages, rinse your mouth with warm water which may decrease the chance of staining. Also, avoid smoking which may turn teeth a gray or slightly yellow color.
