How Your Mouth Affects Your Overall Health (2024)

What’s my mouth’s function?

Your mouth supports many daily functions, including:

  • Breathing.
  • Talking.
  • Chewing.
  • Tasting.
  • Swallowing.
  • Eating.
  • Drinking.

Mouth function in digestive system

Your mouth is where digestion begins. When you chew food, your salivary glands make saliva (spit). Saliva helps break down starches in the foods you eat. Then your tongue moves the food into your throat, down through your esophagus and into your stomach.

Mouth function in respiratory system

Like your nose, your mouth brings air into your lungs. Since your mouth is larger than your nose, it brings in more air. And because the air doesn’t have to travel as far, your body can use it faster.

But unlike your nose, your mouth doesn’t have a filtration system. When you breathe through your nose, it filters, warms and moistens it. Tiny hairs (cilia) sweep mucus into the back of your throat where you swallow it, and then your stomach neutralizes it. Breathing mainly through your mouth (mouth breathing) can dry out your gums and cause issues like bad breath and dry mouth.
