Knowledge about teeth:
The human teeth function to mechanically break down items of food by cutting and crushing them in preparation for swallowing and digesting. Humans have four types of teeth: incisors, canines, premolars, and molars, which each have a specific function. The incisors cut the food, the canines tear the food and the molars and premolars crush the food. The roots of teeth are embedded in the maxilla (upper jaw) or the mandible (lower jaw) and are covered by gums. Teeth are made of multiple tissues of varying density and hardness.
Humans, like other mammals, are diphyodont, meaning that they develop two sets of teeth. The first set (called the "baby", "milk", "primary", or "deciduous" set) normally starts to appear at about six months of age, although some babies are born with one or more visible teeth, known as natal teeth. Normal tooth eruption at about six months is known as teething and can be painful.
Humans usually have 20 primary (deciduous, "baby" or "milk") teeth and 32 permanent (adult) teeth. Teeth are classified as incisors, canines, premolars (also called bicuspids), and molars. Incisors are primarily used for cutting, canines are for tearing, and molars serve for grinding. |
