Answer:
Teeth are one of the strongest parts of the human body. It is mainly composed of proteins (collagen) and minerals (calcium). Apart from the digestion, teeth also play an important role in our speech. An adult will have 32 teeth, including the Wisdom teeth. Molars are the first permanent teeth to develop in, and most of the adults will have their complete set of permanent teeth in place by the age of 21.
Overall adults have 32 teeth in total, called permanent or secondary teeth, and it includes:
Eight incisors – Four incisors in the upper jaw and four incisors in the lower jaw.
Four canines – Two canines in the upper jaw and two canines in the lower jaw.
Eight premolars– Four premolars in the upper jaw and four premolars in the lower jaw.
Twelve molars- Six molars in the upper jaw and six in the lower jaw. It also includes four wisdom teeth.
Babies are born toothless as their primary source of food is mother’s milk. As the babies start to wean, milk teeth gradually start to appear. Milk teeth get replaced by permanent teeth by the time the individual turns six years old. Among the four types of teeth, the lower incisors are the first primary teeth to develop in, and most kids will have all their twenty primary teeth by age 3, which includes:
Eight incisors – Four incisors in the upper jaw and four incisors in the lower jaw.
Four canines – Two canines in the upper jaw and two canines in the lower jaw.
Eight molars – Four molars in the upper jaw and four molars in the lower jaw.
Also, during this phase, an individual will have a combination of milk and permanent teeth. Consequently, this stage is called mixed-stage.
