20 Things That Can Ruin Your Smile

Food, drinks, and unhealthy habits that are wreaking havoc on your teeth and gums by Kristin Koch

But even if you brush, use white strips, and visit your dentist twice a year, it may not be enough. Here are some factors that can wreak havoc on your teeth and gums, and put a serious damper on your smile.

Sports drinks

In the last decade, sports beverages have become increasingly popular, but they aren't great for your teeth.

"Scientific research has found that the pH levels in many sports drinks could lead to tooth erosion due to their high concentration of acidic components, which could wear away at the tooth's enamel," says David F. Halpern, DMD, FAGD, president of the Academy of General Dentistry.

Additionally, these drinks are often high in sugars that act as "food" for acid-producing bacteria, which then sneak into the cracks and crevices in your teeth, causing cavities and tooth decay.

Bottled water

Tap water often contains fluoride—about 60 percent of people in the U.S. have fluoride in their water supply. However, most bottled waters contain less fluoride than recommended for good oral health (it will be listed as an ingredient on the label if it is an additive).

"Fluoride makes the entire tooth structure more resistant to decay and promotes remineralization, which aids in repairing early decay before damage is even visible," explains Academy of General Dentistry spokesperson, Charles H. Perle, DMD, FAGD. "Studies have confirmed that the most effective source of fluoride is water fluoridation."
