They're replaced by a set of 32 permanent teeth, which are also called secondary or adult teeth. Reviewed by: Larissa Hirsch, MD. Larger text size Large text size Regular text size. Why Are the Mouth and Teeth Important? What Do the Parts of the Mouth Do? The membrane-covered roof of the mouth is called the palate PAL-it : The front part consists of a bony portion called the hard palate.
The hard palate divides the mouth and the nasal cavity above. The fleshy rear part is called the soft palate. The soft palate forms a curtain between the mouth and the throat, or pharynx, to the rear. When we swallow, the soft palate closes off the nasal passages from the throat to prevent food from entering the nose. The soft palate contains the uvula YOO-vyoo-luh , the dangling flesh at the back of the mouth.
The tonsils are on either side of the uvula and look like twin pillars holding up the opening to the throat, or pharynx FAR-inks. Each type of tooth plays a role in the chewing process: Incisors are the squarish, sharp-edged teeth in the front of the mouth that cut foods when we bite into them. There are four on the bottom and four on the top. On either side of the incisors are the sharp canines.
The upper canines are sometimes called eyeteeth or cuspids. See more from our free eBook library. A description of the oral cavity from the edition of Gray's Anatomy of the Human Body. Propulsion and Peristalsis. Accessory Organs. Nutrients In, Waste Out. Common Diseases and Disorders.
This is an example of mechanical digestion. The teeth cut and crush food, and the pieces are mixed with saliva to form a ball of food called a bolus. There are different types of human teeth, with a different structure and function:. Tooth decay happens when the hard outer enamel of the tooth is damaged.
However, if you are eating a healthy diet, but not able to chew your food as nature intended, your efforts will be diminished and you could be missing out on some of the very important nutrients contributing to your overall health. The most natural process for replacing missing teeth is with dental implants.
Dental implants duplicate the actual roots of your missing teeth and allow you to chew your food naturally, exercising your gums to produce the proper amount of saliva and break down nutrients through the digestive process. Since dental implants duplicate your natural teeth, their function of acting as incisors, canine or premolar teeth will save the health of your dental bone as well as the health of your body.
