The teeth are connected with the walls of the tooth sockets and anchored in the jaws by the periodontal ligament and the cementum.
The ligament is made up of connective tissue and contains collagen fibers.
These fibers are especially strong so that the teeth can withstand the great pressure put on them while we chew..
Your teeth should meet together like cogs in a wheel.
The pointed ends of the upper teeth should fit perfectly between two teeth on the bottom, while the upper teeth should sit slightly in front of your lower teeth..
The root of a tooth descends below the gum line, into the upper or lower jawbones, anchoring the tooth in the mouth.
Different types of teeth have a different number of roots and root formations.
Typically incisors, canines and premolars will have one root whereas molars will have two or three..

They are seated within the upper and lower alveolar bone in the maxilla and mandible respectively and this exclusive type of joint is known as gomphosis. The teeth are divided into four quadrants within the mouth, with the division occurring between the upper and lower jaws horizontally and down the midline of the face vertically.
There are thirty-two teeth in total in the oral cavity of an adult dentition. One half, or sixteen, are embedded in the maxilla, while the lower half are situated within the mandible.The teeth are arranged in the mouth in 2 arches that contain 2 quadrants each (16 teeth in each arch, 8 teeth in each quadrant in the permanent dentition). The top arch is the maxillary arch and it is fixed. The bottom arch is the mandibular arch and it is capable of movement through the temporomandibular joint.Also, teeth are located by referring to them as either anterior or posterior. The anterior teeth are located in the front of the mouth (the incisors and the cuspids). They are also visible when a person smiles. On the other hand, the posterior teeth are located at the back of the mouth (bicuspids and molars).The crown of each tooth projects into the mouth. The root of each tooth descends below the gum line, into the jaw. Cavities (caries): Bacteria evade removal by brushing and saliva and damage the enamel and deeper structures of teeth. Most cavities occur on molars and premolars.
