Abscess: an infected, inflamed area containing pus, usually caused by problem tooth.

Abutment: a tooth or root that is fitted with a crown to support a bridge or partial denture.

Alloy: a mixture of two or more metals. Several alloys are used to repair teeth: noble (mostly silver), high noble (mostly gold) and "base" metals. The cost of a filling or crown depends on which alloy is used.

Amalgam: a metal alloy used in filling cavities.

Base metal: metal alloys used for partials or crowns which contain no precious metals.

Bitewing x-ray: films of upper and lower teeth used to check for decay between teeth and under gums.

Bonding: a cosmetic procedure that restores damaged teeth.

Bridge: a non-removable replacement for missing teeth made with crowns and pontics.

Cavity: tooth decay caused by bacteria which, if not treated, can destroy the tooth.

Cephalometric x-ray: used to make precise measurements for braces.

Crown: an artificial tooth or cap which covers a tooth weakened by decay.

Dental Implants: made of titanium and surgically screwed into the patient's jaw bone. A false tooth then sits on top of the implant.

Dentures: an artificial substitute for natural teeth and surrounding tissues.

Onlay: a precision cast filling, usually made of gold or porcelain, covering the entire chewing surface of the tooth; larger than an inlay.

Oral surgery: a dental specialty limited to the surgical removal of teeth and the treatment of disease, deformities, and defects of the jaws and associated structures.

Orthodontics: the alignment of teeth, usually through the use of braces.

Osseous surgery: repair of the bone structure supporting the teeth that has been damaged by gum disease.

Panoramic x-ray: a complete view of the teeth, jaws and surrounding bone on one film.

Partial denture: removable artificial teeth that keep the remaining natural teeth from changing position and improve chewing ability.

Pediatric Dentistry: a dental specialty limited to treatment of children from birth through adolescence.

Pedicle soft tissue: graft replacement of damaged gum tissue.

Periapical x-ray: close-up of an individual tooth and the surrounding tissue.

Prosthodontics: a dental specialty limited to the restoration to the natural teeth and/or the replacement of missing teeth. Pulp: the live tissue within the tooth.

Pulp capping: the use of medicine on a decayed part of a tooth to protect the pulp and help healing.

Pulpotomy: partial or complete removal of damaged dental pulp to relieve pain. A root canal is usually recommended to save the tooth.

Quadrant: one-fourth of the mouth.

Reline: to add new material on the underside of a denture to improve the fit and chewing ability.

Resin filling: a tooth-colored plastic material used instead of alloys for a less noticeable, more natural appearance.

Root canal: a treatment used on a tooth with damaged pulp to stop infection and save the tooth. The pulp is completely removed, the inside of the tooth is sterilized and sealed to prevent infection.

Scaling and root planing: a thorough cleaning of tooth surfaces below the gum line to eliminate inflammation and control disease, usually performed during several visits and under local anesthetic.

Sealant: a plastic coating applied to teeth to prevent decay.
