With the dental technology advancements that have been made in the last few decades, terms may come up in conversation that you have not heard before.

Definitions of Dental Terms

Amalgam - Silver-colored filling material; may also be referred to as a restoration or filling.

Bitewings - X-rays of the top and bottom molars and pre-molars to show decay between teeth or under fillings.

Bonding - Bonding is an adhesive dental restoration technique. Bonding is a procedure to adhere tooth-colored resin to the tooth's surface, creating a bond. Bonding is performed by Herrin cosmetic dentists with a tooth-colored composite resin to repair and/or change the color or shape of a tooth. Resin is used for bonding due to its similarities to enamel. The composite resin bonding process is where the resin is bonded to a tooth's surface, but then sculpted into shape, hardened, and polished.

Bridge - A non-removable appliance that replaces one or more missing teeth with false teeth and attaches to healthy teeth.

Calculus (Tartar) - Hardened plaque on teeth, requiring scaling to remove.

Caries - Cavities and decay.

Complete Mouth Survey - (CMS) Multiple X-rays taken of the entire dental structure. For an adult, approximately 16-21 films.

Composite - A tooth colored filling material; also referred to as a filling.

Cosmetic Dentistry - Beautifying teeth and smile through bleaching, bonding, closing spaces, and improving appearance of teeth.

Intra-oral Camera - An intra-oral camera is a small video camera your dentist uses to view and magnify oral conditions. With many intra-oral cameras images may be printed by your Herrin dental professionals.

Radiographs - X-rays.

Recall - Appointment for a patient who is returning for maintenance or follow up care.

Restoration - Filling used to restore the tooth.

Teeth structure abnormality definitions:

  • Amelogenesis imperfecta - A condition in which enamel does not form properly or at all.
  • Dentinogenesis imperfecta - A condition in which dentin does not form properly and is sometimes associated with osteogenesis imperfecta.
  • Dentin dysplasia - A disorder in which the roots and pulp of teeth may be affected.
  • Regional odontodysplasia - A disorder affecting enamel, dentin, and pulp and causes the teeth to appear "ghostly" on radiographs.

Tooth size abnormality

  • Microdontia - A condition where teeth are smaller than the usual size.
  • Macrodontia - When teeth are larger than the usual size.

Teeth number abnormality:

  • Anodontia - The total lack of tooth development.

  • Ectopic enamel - Enamel found in an unusual location, such as the root of a tooth.
  • Taurodontism - A condition where the body of the tooth and pulp chamber is enlarged.
  • Hypercementosis - Excessive formation of cementum, which may result from trauma, inflammation, acromegaly, rheumatic fever, and Paget's disease of bone.
