teeth

• The tooth is composed of different structures:

  • Crown: the top part of the tooth, from the top to where the gingiva is
  • Neck: where the gingiva firmly connects to the tooth
  • Root: below the neck, extending down to the root of the tooth
• Enamel:

  • Outer hard substance of the tooth, hardest substance in the body
• Dentin:

  • Inner core of the tooth, protein-rich material produced by odontoblasts
• Pulp cavity:

  • Contains pulp, connective tissue, arteries, veins, and nerves supplying cells within the tooth
• Root canal:

  • Canal carrying arteries, veins, and nerves towards or away from the pulp cavity
• Alveolar artery, alveolar vein, and alveolar nerves supply the tooth
• Cementum:

  • Anchors the tooth to the periodontal membrane
• Alveolus:

  • Socket where the tooth sits, connected to the bone by the periodontal ligaments
• Periodontal membrane:

  • Pink membrane containing periodontal ligaments connecting the tooth to the bone
• Gingiva:

  • Tissue surrounding the tooth, helps keep the tooth in place and prevents the spread of microorganisms
• Maxillary teeth:

  • Molars (third, second, first)
  • Premolars (second, first)
  • Canine
  • Lateral incisor
  • Central incisor
• Mandibular teeth:

  • Central incisor
  • Lateral incisor
  • Canine
  • First premolar
  • Second premolar
  • First molar
  • Second molar
  • Third molar
• Hard palate:

  • Part of the maxillary bone
• Soft palate:

  • Posterior to the hard palate, contains soft connective tissue and muscle
• Palatoglossal arch:

  • Arch connecting the soft palate to the tongue
• Uvula:

  • Structure at the back of the throat
• Inferior alveolar nerve:

  • Nerve supplying the mandibular teeth
• dentin makes up most of the tooth, it's yellowish colour gives the tooth its natural colour
• pulp contains blood vessels and nerves that supply nutrients to the dentin and enamel
• cementum is found on the root surface of the tooth, it attaches the tooth to the periodontium
• the pulp cavity houses the dental pulp which consists of blood vessels, nerves and lymphatic vessels
• enamel is the outermost layer of the tooth, it covers the crown (the part above the gum)
• root is the part of the tooth below the gums
• crown is the visible portion of the tooth
• The crown is the part of the tooth above the gums
• periodontium consists of gingiva (gums), cementum, ligaments and bone
• gingiva covers the necks of the teeth and provides protection from bacteria
• crown - the visible part of the tooth above the gums
• the gingival sulcus is where the gum meets the tooth
• crown is the visible part of the tooth
• dentin is the hard tissue beneath the enamel
• root - the part of the tooth below the gums
• The root extends into the jaw bone
• periodontal ligament holds the tooth into place by connecting the cementum with alveolar bone
• gingiva is the soft tissue that surrounds the necks of the teeth
• cementum is a thin layer of calcified material covering the root surface
• The root is the part of the tooth that extends into the jawbone
• ligament attaches the roots to the alveolar process of the mandible or maxilla
• apex is the tip of the root
• gingiva is the soft tissue covering the jaw bones
