Teeth With Jaw

Specifications of Human Jaw Structure

• Total Teeth: 32 (including 4 third molars/wisdom teeth).
• Dental Arches: Crescentic formation of 16 upper (maxillary) teeth and 16 lower (mandibular) teeth.
• Attachment: Teeth are secured in bony sockets called alveoli via a fibrous joint (dentoalveolar syndesmosis) and the periodontal ligament.
• Visible Part: The Crown (covered in enamel).
• Embedded Part: The Root (covered in cementum).
• Jaw Muscles: The mandible (lower jaw) is moved by the masseter and temporalis muscles, crucial for mastication.

Primary vs. Permanent Teeth Specifications

• Permanent Dentition: 32 teeth (including premolars and third molars).
• Deciduous Dentition (Primary): 20 teeth. Children lack premolars and third molars.

Tooth Anatomy Description

• Enamel: Hardest outer layer of the crown.
• Dentin: Beneath the enamel, forming the core.
• Pulp: Central chamber containing nerves and blood vessels.
• Gingiva: The gums that cover the bony alveolar processes.
