Dental Terms

Acid etching: process of altering tooth surfaces by applying acids such as phosphoric acid.

Anterior teeth: The incisors and canines.

Bitewing radiograph: intraoral film that shows only the crown portions of opposing teeth in the biting position on the same film.

Bleaching: the use of chemical oxidizing agents to lighten discolored teeth.

Buccal: The facial surface facing the cheek in posterior teeth.

Canines: The third tooth from the midline located at the “corner” of the mouth.

Caries: the infectious disease that progressively destroys tooth substance, beginning on the enamel by demineralization or on the cementum

Complete Denture: a removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla or mandible.

Composite resin: resinous filling material formed by a reaction of resin monomers and inorganic fillers such as silicate or quartz.

Crown: the portion of a tooth covered by enamel or exposed in the mouth.

Crown restoration: a restoration that covers the entire anatomic crown of the tooth.

Dental Amalgam: a dental filling material composed of mercury and metals - silver, copper, zinc, and tin. An amalgam is a combination of mercury and a metal.

Dentin: the part of a tooth under the enamel.

Diastema: A space between the teeth

Distal: The surface of a tooth away from the midline.

Edentulous: without teeth

Enamel: The hard outer coating of a tooth that is exposed in the mouth

Facial: The surface of teeth closest to the face.

Incisors: The first two teeth adjacent to the midline

Implant: Superstructure:

Incisal: The chewing or biting surface of an anterior tooth.

Inlay/onlay: a laboratory fabricated restoration that covers one, two, or three surfaces of the prepared tooth and is bonded or cemented in the tooth.

Interproximal space: The area between adjacent tooth surfaces.

Labial: The facial surfaces close to the lips of anterior teeth.

Lingual: The surface closest to the tongue of mandibular teeth.

Malocclusion: An abnormal or malpositioned relationship of the maxillary and mandibular teeth.

Class I: normal tooth relationship

Class II relationship when the mandible is retruded

Class III relationship when the anterior teeth are edge-to-edge.

Mandible: The bone holding the lower part of the dentition that is capable of moving

Maxilla: The upper part of the dentition which is a part of the skull.

Mesial: The surface of a tooth toward the midline.

Midline: A line dividing the right and left side of the body.

Mixed dentition: When both primary and permanent teeth are present in the mouth.

Molars: The sixth, seventh and eighth (wisdom tooth) from the midline.

Occlusal: The chewing surface of posterior teeth.

Overbite: The vertical distance or overlap between the incisal edges of the anterior teeth.

Overjet: The horizontal distance or overlap between the maxillary and mandibular anterior teeth.

Palatal: The lingual surface of maxillary teeth

Palate: The bone on the roof of the mouth.

Panoramic radiograph: a film in which a continuous image of both maxillary and mandibular dental arches and associated structures is obtained.

Periodontium: The bone and tissue surrounding a tooth.

Permanent dentition: The 32 secondary teeth or “adult teeth”.

Posterior teeth: The premolars and molars.

Premolars: The fourth and fifth teeth from the midline.

Primary dentition: The first dentition of 20 teeth commonly called “baby teeth”.

Proximal: The tooth surfaces adjacent to each other

Pulp: The hollow inside of a tooth containing nerves and blood vessels

Radiograph: visible image produced on a radiation-sensitive film emulsion by exposing the film to radiation and chemicals so that a negative is produced. Also called an x-ray film, radiogram, roentgenogram, and roentgenograph.

Root: The portion of the tooth covered by cementum or imbedded in bone

Succedaneous: the term for the permanent teeth that replace primary teeth of the same type

TMJ: The joint between the mandible and the skull.

Veneer: an overlay or thin layer of a composite resin or ceramic used to cover the facial surface of a tooth.
