You might not believe it, but tooth decay became an epidemic only after humankind learned how to eat sugary and starchy foods. Sugars from candy, dried fruits, carbonated drinks, and white bread can stick to your teeth, which will attract plaque and gingivitis-causing bacteria. Starches from chips and other junk food can also leave bits of food in your teeth.
So drink fresh water instead of soda or synthetic fruit juices. Carrots, fruits, nuts, seeds, and whole grains are healthier alternatives to candy, chips, and white bread. If you can’t resist the urge to chew on something, especially when you’re hungry or waiting for an appointment, you can try sugarless chewing gum.
