| tooth replantation | Reinsertion of a tooth into the alveolus from which it was removed or otherwise lost. (12 Dec 1998) |
|---|---|
| tooth resorption | Resorption of calcified dental tissue, involving demineralization due to reversal of the cation exchange and lacunar resorption by osteoclasts. There are two types: external (as a result of tooth pathology) and internal (apparently initiated by a peculiar inflammatory hyperplasia of the pulp). (12 Dec 1998) |
| tooth root | The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots. (12 Dec 1998) |
| tooth root sensitivities | Oversensitivity of exposed roots of teeth to cold, hot, and sour foods because those roots are no longer protected by healthy gum and bone. Chronic gum disease contributes to toothache due to root sensitivities. The roots are the lower 2/3 of the teeth that are normally buried in bone. The bacterial toxins dissolve the bone around the roots and cause the gum and the bone to recede, exposing the roots. The sensitivities may be so severe that the person avoids any cold or sour foods. (12 Dec 1998) |
| tooth sac | A capsule that encloses the developing tooth. (05 Mar 2000) |
| tooth spasms | Infantile convulsions associated with teething. (05 Mar 2000) |
| tooth, supernumerary | An extra tooth, erupted or unerupted, resembling or unlike the other teeth in the group to which it belongs. Its presence may cause malposition of adjacent teeth or prevent their eruption. (12 Dec 1998) |
| tooth transplantation | The transfer of a tooth from one alveolus to another. (05 Mar 2000) |
| tooth, unerupted | A normal developing tooth which has not yet perforated the oral mucosa or one that fails to erupt in the normal sequence or time interval expected for the type of tooth in a given gender, age, or population group. (12 Dec 1998) |
| torsion of a tooth | Rotation of a tooth in its socket. (05 Mar 2000) |
| tricuspid tooth | A tooth having a crown with three cusps. (05 Mar 2000) |
| tubercle of tooth | A small elevation on some portions of a crown produced by an extra formation of enamel. Synonym: tuberculum dentis, crown tubercle, tubercle of tooth, tuberculum coronae. (05 Mar 2000) |
| Turner's tooth | Enamel hypoplasia involving a solitary permanent tooth; related to infection in the primary tooth that preceded it or to trauma during odontogenesis. (05 Mar 2000) |
| extrusion of a tooth | Elongation of a tooth; movement of a tooth in an occlusal or incisal direction. (05 Mar 2000) |
| facial surface of tooth | The surface of a tooth that faces the buccal or labial mucosa of vestibule of the mouth; opposite to the lingual surface of tooth. Synonym: facies vestibularis dentis, facies facialis dentis, buccal surface, facial surface of tooth, facies buccalis, facies labialis, labial surface. (05 Mar 2000) |
