| Amelogenis Imperfecta | Hereditary form of enamel hypocalcification |
| Ankylosis | Fusion of the cementum of a tooth with the alveolar bone |
| Anodontia | No teeth at all present in the jaw |
| Bicuspids | Same as premolars |
| Cementoma | Cementum tumor at root tip that destroys surrounding bone |
| Concrescence | Two adjacent teeth or roots that fuse by their cementum |
| Congenital | Occurring at or before birth; may or may not be hereditary |
| Congenitally missing | Condition of never having been developed |
| Conical tooth | A supernumerary tooth that is cone shaped |
| Curve of spee | Anatomic line beginning at the tip of the canines and following the buccal cusps of premolars and molars when viewed from the buccal aspects of the first molars |
| Cusp of carabelli | Fifth lobe of a maxillary first molar |
| Dens in dente | An invagination of the outer surface of the tooth crown turning itself inward |
| Dental caries | Damage to a tooth that can happen when decay-casuing bacteria in your mouth make acids that attack the tooth's surface, or enamel. Also called tooth decay, or cavities |
| Dentiongenesis imperfecta | Hereditary imperfect dental formation |
| Developmental grooves | Fine depressed lines in the enamel of a tooth that mark the union of the lobes of the crown |
| Developmental lobes | Major growth centers of a tooth |
| Dilacerated tooth | Tooth with sharply bent root |
| Distomolar | Fourth molars |
| Dwarfed root | tooth with very short roots in comparison with the crown |
| Edentulous | An area without the presence of teeth |
| Enamel dysplasia | Abnormality of enamel growths |
| Enamel fluorosis | A form of enamel hypo calcification where enamel is discolored because of an excess of fluoride in the tooth structure |
| Enamel hypocalicification | |
| Enamel hypoplasia | Enamel that is not as dense as regular enamel |
| Enamel pearls | Small rounded elevations of enamel, usually developing in the bifurcations of trifurcations of teeth, considered abnormal structures |
| Eruptive stage | Period of eruption from the completion of crown formation until the teeth come into occlusion |
| Exfoliation | Shedding or loss of primary tooth |
| Extrinsic | Originating outside a structure |
| Familial tendency | When an anomaly occurs when frequently than usual in one family |
| Flexion | A bend or twist in the root, not involving the crown |
| Fusion | Two teeth that fuse at their dentin while they are developing. Also, a term used for the process of formation of the hard and soft palates |
| Gemination | A tooth that partially or fully divides into two teeth while developing |
