Swap out soda with water
When you eat sugary foods or sip sugary drinks for long periods of time, plaque bacteria use that sugar to produce acids that attack your enamel, the hard surface of your tooth. Most carbonated soft drinks, including diet soda, are acidic and therefore, bad for your teeth. Caffeinated beverages, such as colas can also dry out your mouth. If you do consume soft drinks, try to drink alongside a cup of water.
