| Bony socket that holds the tooth | Alveolus |
| Can stretch and then return to there original state | Elastic fibers |
| The very ends of the collagen fibers that are embedded within the hard tissue | Sharpey's fibers |
| Extends from the crestal bone to the cementum of the tooth | Alveolar crest fibers |
| Cells of mature bone | Osteocytes |
| Thin, nonkeratinized epithelium | Attatchment epithelium |
| Gingiva that is not attatched to the alveolar bone | Free gingiva |
| Fingerlike extensions of epithelim into the lamina propria found in the free gingiva | Rete pegs |
| Run from the cervical tooth to surrounding gingiva, and are located in the free gingiva above the alveolus | Dentogingival fibers |
| Begin at the crestal bone and end at the bottom of the alveolar bone, attatching to the gingiva that covers this bone | Alveologingival fibers |
| Special group of fibers that run from cervix to cervix of the teeth, across the crestal bone | Transseptal fibers |
| Encircles each tooth, gives support to the gingival collar | Circular fibers |
| Peaks of free gingiva | Papillae |
| Hard thin layer that lines the alveolus | Lamina dura |
| Points of bone found between the teeth | Crestal bone |
| Tissue that lines the periodontal pocket | Sulcular epithelium |
| Gingiva directly adherent to alveolar bone | Attatched gingiva |
| Soft tissue that surrounds the teeth | Gingiva |
| Space in bone that contains the developing tooth | Crypt |
| Large collagen fiber bundles that attatch the tooth alveolus | Principal fibers |
