The Human Mouth. The human mouth is a complex structure that consists of both hard and soft tissues forming a hollow cavity. The mouth anatomy features several components including the jaws, teeth, gums, tongue, palate, cheeks, lips, which all together contribute in making possible the various functions of the mouth.
There should be 32 teeth in the human mouth, including four wisdom teeth. However, the average number is only 25.7, according to the Department of Health. Often teeth are taken out because of lack of space. Wisdom teeth, which appear between the ages of 18 and 25, are frequently removed for this reason.
