| secondary teeth | <dentistry> The permanent teeth, i.e. The second group of teeth to come in. (08 Jan 1998) |
| Horner's teeth | Incisor teeth having a horizontal hypoplastic groove. (05 Mar 2000) |

| skin of teeth | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth.
