The importance of teeth in humans

A person’s teeth are not only there to be attractive in the photos. Teeth play a role in nutrition and overall health. Teeth allow you to follow a healthy diet and stay well fed by preparing the food you eat for swallowing and digestion. Regular dental care is important to keep teeth healthy.

Types of teeth

The incisors and canines constitute the front teeth. The incisors have straight edges, designed to cut food, such as apples and carrots. They also act as shovels, guiding the food in the mouth. The canines are slightly pointed and spear-shaped. They are designed to hold food by biting so food can be torn into smaller pieces that can be chewed, such as by biting the flesh of a chicken thigh. The posterior teeth are called premolars and molars. These have large chewing surfaces to help crush and crush foods so they can be swallowed easily. They are in the back of the mouth, where the jaws give them the strength to chew.

Milk and permanent teeth

People have two sets of teeth during their lifetime. A complete set of baby teeth has 20 pieces. Babies usually have their first tooth about 6 months old. As they pull out more teeth, they are able to chew a wider variety of foods. Milk teeth are important for chewing and also maintain the space for larger permanent teeth to grow properly. Therefore, it is important to take care of the baby’s teeth even though they eventually fall out. Around 6 years, the baby’s teeth begin to fall to make room for the permanent teeth. Around age 12, a child has generally lost all of his or her baby’s teeth. Adults have larger mouths and need more teeth to chew.


A typical diet includes both food of plant origin and animal origin. Different types of teeth work together to break down various types of food for digestion. Without proper maintenance, the teeth can be victims of gum disease or decay, which can lead to loss of parts. This can lead to changes in what a person is able to eat and can cause health problems associated with poor nutrition.

Speech and appearance

Your teeth also help you talk and contribute to your personal appearance. Speech is affected by the way the teeth come together, the movement of the jaw and the movement of the tongue around it. Appearance is affected by the bite of the teeth and the surrounding bones. Lack of teeth, crowding, or jawbone size can cause teeth to line up in the wrong way. These problems and loss of teeth lead to changes in facial appearance and profile.
