Make Sure to Brush After Eating These 7 Foods

By now, we all know the basic recipe for healthy pearly whites, including regular brushing and flossing, and a diet rich in teeth-healthy foods. What we might not realize is how some food choices can contribute to the wear and tear of teeth.

So, what makes a food bad for your smile?

In general, foods that are both sugary and sticky are not really great for the teeth.

We all heard about sugary food. Bacteria living in the mouth burn sugars in order to live. The byproduct of this burning is acid, which dissolves tooth enamel and causes cavities

And when foods are sticky, they stay on the teeth longer, which gives a greater chance for bacteria to burn the sugars and do all the evil things that they do.

Acidic foods can also be bad for the teeth, as they could potentially damage the tooth enamel. This means foods and drinks that are both acidic and sugary (like soda), add up to double trouble for teeth.

Saliva is great at helping to naturally wash the mouth of little food particles and can keep food from sticking to teeth, so anything that stalls saliva production — including some medications that facilitate dry mouth — isn’t ideal for tooth health either.

It’s important to note that some of the foods listed below aren’t necessarily bad for health — such as dried fruits — but dental health experts encourage teeth brushing or mouth rinsing after consumption to help prevent decay.

7 Foods That You Want To Brush After Eating

1. Dried Fruits

While dried fruits may be a definite step up from processed fruit snacks, they are still sticky and high in sugar. That means they not only adhere to teeth easily, but the sugar feeds the bacteria in the mouth, which can promote dental erosion.

Regular fresh fruits don’t typically have this problem because — even though they still have sugar — chewing them up promotes saliva and they don’t stick to the teeth.

Fruits are generally pretty safe because they’re good for overall health and they’re chewy, so your average fruit has some substance to it and we chew through it, causing us to salivate more. Saliva is a good thing because it has washing action and it’s a natural buffer to acid.

2. Sugary Drinks

Sugary drinks, such as sodas and sports drinks, are especially bad for teeth when sipping for long periods of time.

“If I have a soft drink or sports drink and I’m sipping it every 20 minutes, my teeth are getting bathed with a constant layer of acid,” Messina says who is a D.D.S., consumer adviser for the American Dental Association. “So sitting down and drinking it all at once, or with a meal, is better than snacking or sipping throughout a meal.”

For this reason, we suggest that parents don’t fill their kids’ sippy cups with sugary drinks, since kids, whose teeth are still developing, tend to sip at those drinks over long periods of time.

3. Hard Candies

For the same reason sipping on sodas all day is bad for teeth, hard candies aren’t ideal for oral health. These sweets pack a double whammy in that they not only stick to the teeth, but they also linger in the mouth for a long time as you wait for them to dissolve.

4. Alcohol

You may not realize it, but alcohol can be bad for the teeth, as it causes natural saliva production to decrease, according to the Yale Medical Group. And again, saliva helps to wash away food particles and provides a buffer against acid.

People who are alcoholics may experience dental and gum disease since alcohol irritates all the soft tissue in the mouth and it decreases the amount of natural saliva.

In terms of the tissue, the skin of the mouth is very delicate and the alcohol is corrosive to the gums, cheeks and skin. It can affect the way the tissue cells divide, which is why people who drink heavily have a greater chance of getting mouth or throat cancer.

5. Citrus/Acidic Foods

Foods high in acid, such as citrus or tomatoes, can promote tooth decay, especially when eaten alone. But these foods are fine to eat so long as you flush your mouth with water after consuming them in order to buffer the acid.

Citrus not only has acid, but also sugar — and people who have a habit of sucking on lemons or limes are actually harmfully bathing their teeth in acid.

If you look in their mouths, their teeth have a shiny, glossy surface — that’s from constant bathing with the acids. They will have almost a peculiar look in that you’ll see it on the front surfaces of their teeth, but not the back sides of the lower front teeth because those are under the tongue — and the tongue protects the surface of teeth.

6. Starchy Foods

Starchy foods, such as potato chips and white bread, easily get trapped in teeth, which can then feed the bacteria that make up plaque.

7. Coffee

Not only do drinks like coffee and tea stain the teeth, they also make the teeth stickier — meaning more food particles can latch on.
