How are teeth attached to the jaw bone?
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..
How do tooth roots work?
The roots are attached to the alveolar bone by periodontal ligaments.
Nerves and blood vessels enter the apical foramen of the tooth to provide innervation and a blood supply.
Dentin surrounds the pulp chamber, which contains odontoblasts, pulp cells, nerves and blood vessels..
How do you identify teeth?
The first thing to realize is dentists use a two-digit numbering system.
So the upper right teeth begin with the number “1” (i.e. 11), the upper left teeth begin with the number “2” (i.e. 21), the lower left teeth begin with the number “3” (i.e. 31), and the lower right teeth begin with the number “4” (i.e. 41)..
What covers the anatomic root of the tooth?
The cementum is the substance that covers the root of the tooth.
It is also very thin and not as hard as the enamel but has a similar hardness to bone.
Cells known as cementoblasts form cementum.
There are fibers that project from the cementum and attach it to the alveolar bone..
- The visible part of the tooth is crown; the root part is hidden in the gum.
