Tooth Morphology
Tooth morphology describes the shape, structure, and form of teeth. Learn how crown and root anatomy guides diagnosis, treatment, and restorations.
Category: Dental Anatomy
Dental anatomy is the foundation every clinical decision rests on — knowing where a structure sits, what it does, and how it relates to neighboring tissues. This section of the Rebrief Dental Glossary catalogs the anatomy of the tooth and its supporting structures: enamel, dentin, cementum, and dental pulp inside the tooth itself; the alveolar bone, alveolar process, and alveolar crest of the supporting socket; and the periodontal ligament, gingiva, and gingival sulcus that hold and protect each tooth in place. We cover surface and directional terminology — buccal, lingual, mesial, distal, occlusal — that lets clinicians describe lesions and restorations precisely. You’ll find detailed entries on tooth-specific structures (apical foramen, apical delta, cervical line, cuspal ridge), individual tooth designations across the permanent dentition, and the soft-tissue landmarks that define the periodontium. Each term entry includes a working clinical definition, the anatomical context that matters in practice, and links to related conditions and procedures elsewhere in the glossary. Whether you’re a dental student building a vocabulary, a hygienist refreshing landmarks for a charting course, or a practicing clinician documenting a case, this is a quick reference for the structural terms that show up in records, consults, and patient education materials.

Soft Palate
The soft palate is the muscular, movable partition at the back of the roof of the mouth—essential to swallowing, speech, and sleep health.
Uvula
The uvula is the fleshy projection hanging from the soft palate at the back of the mouth — a key landmark in oral exams, speech, and airway health.
Vestibule
The oral vestibule is the space between the lips, cheeks, and teeth. Learn its anatomy, clinical roles in anesthesia, dentures, and oral lesion detection.
Permanent Maxillary Right Second Premolar
Explore the anatomy and clinical role of the permanent maxillary right second premolar — a vital upper posterior tooth that supports occlusion and chewing.
Permanent Maxillary Right Third Molar
The permanent maxillary right third molar is the upper right wisdom tooth — explore its anatomy, impaction risks, and key clinical considerations.
Root Apex
The root apex is the tapered tip of a tooth’s root and a key landmark in endodontic care. Discover its anatomy, function, and clinical significance.
Permanent Maxillary Right Second Molar
The permanent maxillary right second molar is a key posterior tooth for chewing and occlusion. Learn its anatomy, eruption, and clinical significance.
Permanent Maxillary Right First Premolar
The permanent maxillary right first premolar (tooth #5) has bifurcated roots, two cusps, and is key to occlusion, orthodontic planning, and endodontic care.
Permanent Maxillary Left Second Premolar
The permanent maxillary left second premolar (tooth #13) anchors posterior occlusion. Learn its anatomy, root canal types, and clinical significance.
