root

Pulp

Center - core of the tooth

made of connective tissue , neves/ blood vessels

nerves/ vessels come from the apex ( bottom of tooth root) and provide nourishment and sensory function for the tooth.

Odontoblast

form dentin

special cells linging the pulp

Dentin

Bulk of the tooth

surrounds the pulp

hard as bone

detects heat/ cold/ touch

Primary Dentin

formed before the tooth eruption

Secondary Dentin

Continually formed throughout life

forms the pulp chamber and reduces in size with age, providing protection to the pulp.

Enamel

Hardest tissue in mammals

formed before tooth eruption

enamel stops after eruption and gradually over time looses life ( wear and tear)

susceptible to chipping

Alveolar Bone

Forms the jaw adn the sockets in which the roots of teh teeth are extended

Periodontal Ligaments

tough tissue helps to hold the tooth in the socket

attatches t the cementum of the tooth and the alveolar bone

Gingiva

GUMS

soft tissue that covers the rest of the oeriodontium

gingiva attached to the tooth is harder and can withstadn he forces of chewing

Sulcus

area between the free gingiva and the tooth

Periodontal pocket

the space between the free gingiva and the tooth is known as a “ pocket”

Lateral Canal

Very small cannel that connects the root pulp to the periodontal tissue through which small blood vessels run allowing for nutrient exchange.

Cementum

Hard calcified tissue tha covers the dentin of the root

slowly formed throughout the life of the tooth

assists in supporting the tooth in the jaw and in root repair

Coronal

toward the crown

Apical

to the root

Supragingival

above the gumline

Subgingival

Below the gum line

Buccal
