Bad Breath

Bad breath. Most of us have it sometimes, especially first thing in the morning. But what causes it? And what can you do about it?

Fun Facts

  • Did you know that drinking more water can cure bad breath? When you’re dehydrated, food (and the bacteria that causes stinky breath) stays in your mouth longer. A glass of water helps wash it away.
  • Chewing gum increases spit production, another way to get rid of food – and bacteria.
  • Sometimes bad breath is a sign of disease, such as asthma, kidney disease, or diabetes.
  • Bad breath can also be a sign of gum disease, so a visit to the dentist is a good idea.
  • Have a cold, asthma, tonsillitis, or allergies? Dry mouth and wheezing can also make your breath smell.
  • Being overweight is another cause of bad breath.
  • Morning breath happens because bacteria tend to hang around longer in our mouths while we sleep.


  1. Dehydrate: lacking in moisture
  2. Production: the act of making something
