Foods that Whiten Your Teeth

May 29, 2017

It is common sense that brushing and flossing regularly is the best method of teeth whitening. However, most people don’t realize that the same thing that is a cause of teeth discoloration — food — can be used to whiten teeth.

Apples, according to dentist Jonathan Levine, are natural exfoliants, which, in terms of teeth, means that they remove substances from teeth that you don’t want attached to them. This stain removal is activated by the amount of chewing that apples require. Apples also contain malic acid, and a 2013 study by St. George’s University found that malic acid increases saliva that can be used to clean the mouth.


Carrots can also whiten teeth. Vitamin, A, which is an ingredient of carrots, improves tooth enamel, which in turn makes it less likely that teeth will become discolored. Additionally, eating carrots cues saliva to start working, and saliva is used by the mouth to clean teeth.

Broccoli also serves to fight tooth discoloration. Tooth enamel can be protected by iron, which is contained in broccoli. According to nutrition expert Joan Blake and research published that was published in the European Journal of Dentistry, when iron contacts teeth, it works to prevent acids and other staining agents from sticking to teeth. The stain fighting nature of broccoli is also thanks to how crunchy it is. You have to chew broccoli a lot, and in doing that, it scrubs teeth clean.

Another food to consider is strawberries. You may think that strawberries would turn teeth red, and in fact, they do, but only temporarily. When the red washes away, the teeth will be whiter than before. Strawberries can be thought of as a teeth polisher, as LIVESTRONG.com mentions. Dr. Irwin Smigel, the president of the American Society for Dental Aesthetics, also points out that, like apples, strawberries contain malic acid that extracts materials that discolor teeth. Additionally, according to MSN, strawberries have ellagitannins, which are antioxidants that fight stains.

As the saying goes, “You are what you eat.” When it comes to teeth, you are what you chew. Foods that contain malic acid, iron, and antioxidants are most likely to keep teeth white and give you a beaming smile.
