10 Foods You Didnt Know Were Damaging Your Teeth

December 27, 2016

Most people know candy and other sugary foods wreak havoc on their teeth, but how about fruit?

Youve probably heard brushing and flossing twice a day is the best way to keep your teeth healthy. But some foods cause enough damage to warrant extra cleanings.

How does food damage your teeth?

There are two main elements of food that tarnish your pearly whites: sugar and acid.

Sugars, especially sucrose (table sugar), feed the millions of bacteria already in your mouth. Bacteria feast on your plaque buildup and produce lactic acid, which erodes your tooth enamel. Sucrose is the worst form of sugar because it adheres to teeth very strongly making it (and the bacteria) difficult to remove even when brushing.

Acids naturally occur in many foods, including fruit. In these cases, bacteria arent necessary to produce acid and cause tooth decay. Instead, acidic foods eat away at your enamel and break down your teeth directly.

Generally you can wash away natural acids by drinking water. Ironically, brushing soon after consuming acidic foods or beverages can actually cause more damage. Because teeth are porous, brushing softens them and makes them more susceptible to acid. After eating acidic foods, you should wait at least an hour before brushing.

What foods should you worry about?

In addition to the sugar and acid in foods, you should consider the length of time food is left on your teeth. The more time bacteria have to produce acids, the more damage will be done.

While many of these foods are healthy for other reasons, you should try and care for your teeth soon after eating them. Drinking water with your meal, chewing sugar-less gum, rinsing with an alcohol-free fluoride mouthwash or flossing and brushing with toothpaste reduces the risk of damage.
