Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, too.

Teeth Are Designed for Healthy Eating

Humans are omnivores, which means we can eat both meat and plants. That’s why our teeth have different shapes—they’re designed to help us eat different kinds of food. 

• Incisors, our front teeth, have sharper edges to help cut through meats and other harder foods when we bite.
• Canines, the pointed teeth, help tear food into bite-size bits.
• Premolars are flat topped and have two cusps, or raised points, which help grind food. 
• Molars are the flat-topped teeth in the back of the mouth. They have four cusps to grind and crush food into a paste. 

So: Incisors and canines bite and tear food into smaller pieces, and then molars and premolars crush and grind those pieces into a paste. Bite, tear, crush, grind—that’s a lot of work! But it’s the key to healthy digestion. 

Chewing is the first step in digestion. Digestion means breaking down our food into parts which our bodies can use as fuel to grow. When you chew your food well, it’s easier for your body to break that food down, to swallow it, and to get the proteins, vitamins, and minerals in your healthy diet. 

But when your teeth hurt, it’s hard to chew food well, which makes digestion harder and sometimes uncomfortable. To get the most from your healthy diet, you need healthy teeth!

Teeth Have Other Important Jobs, Too

• They Help Us Speak

Our teeth work with our tongues and lips to form many of the sounds which make up speech. Try saying the word “teeth,” and see how your tongue and teeth work together!

• They Help Shape Our Faces

Our teeth look great in smiles. But there’s more! Your teeth and the way they fit together in your jaw help shape the look of your chin, lips, cheeks, and the front and sides of your face. 

• They Help Make a Healthy Bite

Our teeth and jaws are designed to work together. When something’s not lined up just right, that’s called a malocclusion, or bad bite, and can cause problems with eating, speaking, and self-confidence. Your dentist might recommend orthodontic treatment to help your teeth and jaws look their best and work their best. 

Teeth Can Only Work Their Best with Your Help

You’re in charge! 

• Brush twice and floss at least once every day to clean away plaque and food particles from your teeth. This helps to protect them from cavities. 
• Eat a healthy diet to give you the vitamins and minerals which keep your teeth strong.
• Make sure you wear mouth protection when you play sports or do activities where you may fall, or collide with another person, or be hit with equipment like balls, bats, and pucks.   
• See your dentist regularly for exams and cleanings.
