How Some Foods Stain Teeth

how some foods stain teethChildren usually have brilliant white teeth with a nice even color throughout the enamel, but by the time most people reach adulthood, their teeth have a more yellow tint. Some people’s teeth may even appear gray or brown. These colors are not the natural color of the teeth but are in fact usually due to stains, and the stains are commonly caused by foods and drinks.

Soy sauce, berries, curries, tomato sauce, soda, coffee, tea, and wine are all common offenders. The stain-causing compounds are said to be chromogenic. Chromogens are naturally occurring substances that result in stains when they are oxidized. Although dental enamel is the hardest substance in the human body, it is porous, which allows chromogens to enter the teeth. Hot and acidic foods and drinks can make the matter worse by opening the pores of the teeth and eroding the enamel, allowing the stains to penetrate even more deeply into the teeth.

Stains can seep far into the structure of the tooth where it is impossible to scrub them away. Brushing your teeth regularly with fluoride can reduce the risk of permanent stains, but it may not be enough to eliminate the deeper stains. Teeth whitening treatments that use bleaching compounds such as peroxide are more effective at getting into the dentin and breaking up the oxidized stains.
