metszfogak

Metszfogak are the front teeth of the upper and lower jaws, specialized for cutting and nibbling food. In humans and many mammals they occupy the anterior region of each dental arc, just behind the lips. In the permanent dentition, each arch contains four metsze fogak: two central incisors and two lateral incisors, for a total of eight incisors. In primary dentition there are also four incisors per arch, totaling eight deciduous incisors.

Anatomically, metsze fogak have relatively thin crowns with a sharp incisal edge and single, slender roots, though there is variation in shape and root form among individuals and species. The crowns are designed to contact the lower incisors and upper and lower canines during biting, producing a cutting action that begins the process of food reduction.

Functionally, they play a central role in biting and shaping speech. Their position at the front of the mouth makes them important for aesthetics and for guiding lip movement and the midline alignment of the teeth.

Development and eruption typically follow a pattern where deciduous incisors emerge in infancy (with timing varying among individuals), while permanent central incisors usually erupt around ages 6 to 7 and lateral incisors around ages 7 to 8. By adolescence most people have their full set of permanent metsze fogak.

Variations in crown shape, root length, or enamel thickness occur and can influence wear, alignment, and susceptibility to trauma. In some mammals, incisors are ever-growing or highly specialized, illustrating broader dental diversity beyond humans.
