Teeth are designed for chewing, allowing food to be efficiently broken down for digestion. These 15 facts explain how various types of teeth contribute to the chewing process, making eating easier and more effective.1

Teeth are essential for the mechanical breakdown of food during mastication, cutting, grinding, and crushing food into smaller pieces to aid digestion. This process helps prepare food for swallowing and ensures better nutrient absorption. 1
The incisors, located at the front of the mouth, are specialized for cutting and biting into food. They play a critical role in the initial phase of mastication by slicing through soft or hard food items like fruits and bread.
Canines, the pointed teeth next to the incisors, are designed for tearing and gripping food. They are especially useful when eating tougher foods, like meat, where a strong grip is needed to break the food apart.2
Proper alignment of teeth allows them to come together efficiently during mastication. Misalignment or malocclusion can cause uneven wear on teeth and make chewing less effective, leading to digestive problems. 3
Teeth stimulate saliva production during chewing, which helps moisten food and initiates the chemical breakdown of starches with enzymes. Saliva also acts as a lubricant, easing the swallowing process. 4
Teeth provide sensory feedback to the brain about the texture and hardness of food. This tactile sensation helps regulate the force used in chewing and prevents damage to teeth and gums from hard or sharp objects.
The tongue and cheeks work with teeth to properly position food during chewing. This coordination ensures that food is kept between the teeth for efficient grinding and mixing with saliva. 5
The Temporomandibular Joint (TMJ) allows for the smooth movement of the jaw during chewing. Proper functioning of this joint is critical for the coordinated opening, closing, and side-to-side movements needed for effective chewing.6
Proper chewing facilitated by teeth breaks food down into smaller pieces, increasing the surface area for enzymes to act upon. This leads to better digestion and nutrient absorption in the stomach and intestines. 7
Proper mastication breaks down food into smaller pieces, increasing the surface area for enzymes to act upon. In humans and animals like rabbits, this improves digestion and nutrient absorption in the digestive tract. 8
Teeth adjust the force used depending on the food type. For example, gorillas apply immense force to crush tough plant fibers, while humans use more delicate pressure for softer foods.9
Teeth also support speech by helping form sounds during articulation. Though animals don’t rely on teeth for speech, certain species, like dolphins, use their teeth to create clicks and other sounds for communication. 10
Crowns, fillings, and dental implants can restore the function of damaged teeth, ensuring efficient mastication. These treatments help maintain proper chewing forces and prevent further dental issues. 11
The mastication process strengthens the jaw, face, and neck muscles. Regular chewing exercises these muscles, ensuring they remain strong and functional over time. 12
Rodents possess incisors that continuously grow throughout their lives, essential for effective chewing. These chisel-shaped teeth allow them to gnaw through tough plant material and hard objects, ensuring they can access various food sources.13
