Permanent teeth

Second set of teeth in diphyodonts. The permanent dentition or second dentition are the teeth that form after the deciduous dentition, which are much stronger and larger than the deciduous dentition and which will form the dental system throughout life. These are generally referred to as teeth, which in humans are divided into four groups or families: incisors, canines, premolars and molars.

The teeth in the front of the mouth, known as bicuspids, are made for pulling, cutting, ripping, and holding objects. Thus, each jaw has four incisors, two canines, four premolars, and six molars that make up the permanent dentition. Each side has a cuspid tooth next to the incisors. The upper incisors can detect objects in the mouth by nibbling, thanks to their tactile sensitivity. Like the incisors, it typically has a pointed appearance to break up food particles.

Each type of tooth has different roots, ranging from one for canines, incisors, and premolars to two or three for molars. The third molar's size, roots, cusp pattern, and eruption are frequently variable in humans. In contrast, the molars are only employed for crushing and grinding.
