how soft drinks hurt your teeth

​If you’re like up to half of the American population, you may have had a sugary drink today- and there’s a good chance it was soda.  Drinking high-sugar soft drinks is most commonly associated with obesity, type 2 diabetes, and weight gain.
But sodas can also have ill effects on your smile, potentially leading to cavities and even visible tooth decay.
According to the Centers for Disease Control and Prevention (CDC), men are more likely to drink soda and sugary drinks.  Teenage boys drink the most and get about 273 calories from them per day.  That number falls only slightly to 252 calories in their 20s and 30s.
When you drink soda, the sugars it contains interact with bacteria in your mouth to form acid.  This acid attacks your teeth.  Both regular and sugar-free sodas also contain their own acids, and these attack the teeth too.  With each swig of soda, you’re starting a damaging reaction that lasts for about 20 minutes.  If you sip all day, your teeth are under constant attack.
