*Golla and Slush - In summer we are tempted to consume these icy foods, but they are not good for your teeth.
"Ice-cold beverages make a perfect plot for the food colorings in Slush and Gola to cause tooth stains."
*Tobacco- In addition to being harmful to health, tobacco is also harmful to your teeth. "The coal tar in tobacco causes dark brown or black spots from smoking or chewing tobacco."
