Best and Worst Foods for Your Teeth
It's no secret that drinking too many sugary sodas can breed cavities. What's less well-known is that the acids found in carbonated soft drinks appear to harm teeth even more than the sugar. The upshot? Even sugar-free diet sodas like Diet Coke and Diet Pepsiwhich both contain citric and phosphoric acidcan erode enamel if consumed in large doses.
If you can't do without soda, your best bet is to drink it during a meal, rather than sipping it throughout the day. The food will help neutralize the acid, Messina says, and "the time of exposure to the acid is much shorter."
