18 Things That Happen to Your Body When You Don't Drink Enough Water

Your mouth is dry, and your breath stinks!
Although going to the dentist is low key one of the worst things about life, keeping your mouth healthy is super important for making sure your mouth smells only of freshly-devoured Chicken McNuggets. By drinking water, you're giving your body enough materials to make saliva, and when you've got enough saliva, your body can kill all the bacteria that makes your mouth dry and smelly. "If you’re not producing enough saliva in the mouth, you can get bacteria overgrowth and one of the side reactions of that is bad breath from chronic dehydration," Dr. John Higgins said, speaking to the website Everyday Health.
