| tooth, deciduous | The 20 teeth of the first dentition, which are shed and replaced by the permanent teeth, usually by the age of six years. All deciduous teeth are normally expected to erupt by the age of two and a half years. (12 Dec 1998) |

| tooth demineralization | A tooth's loss of minerals, such as calcium in hydroxyapatite from the tooth matrix, caused by acidic exposure. An example of the occurrence of demineralization is in the formation of dental caries. (12 Dec 1998) |
| tooth discoloration | Any change in the hue, colour, or translucency of a tooth due to any cause. Restorative filling materials, drugs (both topical and systemic), pulpal necrosis, or haemorrhage may be responsible. (12 Dec 1998) |
| tooth erosion | Progressive loss of the hard substance of a tooth by chemical processes that do not involve bacterial action. (12 Dec 1998) |
| tooth exfoliation | Physiologic loss of the primary dentition. (zwemer, boucher's clinical dental terminology, 4th ed) (12 Dec 1998) |
| tooth extraction | The surgical removal of a tooth. (12 Dec 1998) |
| tooth form | The characteristics of the curves, lines, angles, and contours of various teeth which permit their identification and differentiation. (05 Mar 2000) |

| tooth injuries | Traumatic or other damage to teeth including fractures (tooth fractures) or displacements (tooth luxation). (12 Dec 1998) |
| tooth ligation | The binding together of teeth with wire for stabilization and immobilization following traumatic injury or orthognathic surgery, or during periodontal therapy. (05 Mar 2000) |
| tooth loss | The failure to retain teeth as a result of disease or injury. (12 Dec 1998) |
| tooth mobility | Horizontal and, to a lesser degree, axial movement of a tooth in response to normal forces, as in occlusion. It refers also to the movability of a tooth resulting from loss of all or a portion of its attachment and supportive apparatus, as seen in periodontitis, occlusal trauma, and periodontosis.
