Cold sore – Cold sores are tiny blisters that develop on the lips or around the mouth. The herpes simplex virus strain HSV-1 normally causes them. They usually clear within 7 to 10 days without treatment.

Contouring – The process of shaving or reshaping teeth.
Crown or Cap– An artificial tooth replacement in ceramic or metal that restores missing tooth structure by surrounding the remaining coronal tooth structure.
Cusps – The pointed parts on a tooth’s chewing surface.
Cuspids – Front teeth that typically have a protruding edge. Generally 3rd from the midline.
Dentin – The tooth layer underneath the enamel.
Denture – A removable set of teeth.
Endodontics – A field of dentistry that addresses problems affecting the tooth’s root or nerve.
Fluoride – A mineral usually present in trace amounts in water and food. The Canadian Dental Association supports the appropriate use of fluorides in dentistry as one of the most successful preventive health measures in the history of health care.
Fluorosis – A harmless over-exposure to fluoride resulting sometimes in tooth discoloration.
Gingiva –gum tissue.
Gingivitis – Swelling of the gums caused by plaque.
Impacted teeth – A condition in which a tooth fails to erupt or only partially erupts. Most commonly related to wisdom teeth or Canines.
Implant – A permanent replacement (that looks like a screw in the bone) for a missing tooth. It is commonly made of titanium
Incisor – Front teeth with cutting edges.
Laminate veneer – A shell made of glass like structure that is bonded to the enamel of a front tooth to improve the shape or colour of teeth. The shell is usually thin and made from porcelain resin.
Malocclusion – A malocclusion is a misalignment or incorrect relation between the teeth of the two dental arches. It is most commonly seen as crowding or spacing between teeth due to discrepancy between the size of teeth and jaws
Mandible – The lower jaw.
Maxilla – The upper jaw.
Molar – Back teeth that are used for chewing and grinding the teeth.
Onlay – A filling designed to protect the chewing surface of a tooth.
Orthodontics – A field of dentistry that deals with tooth and jaw alignment.
Overdenture – A non-fixed dental appliance applied to a small number of natural teeth or implants.
Palate– Roof of the mouth.
Partial denture– A removable appliance that replaces missing teeth.
Pediatric Dentistry– A field of dentistry that deals with children’s oral health
Periodontal disease– Infection of the gum tissues and the underlying bone
Perio pocket– When you have periodontal disease, the supporting tissue and bone around teeth is destroyed, forming “pockets” around the teeth.
Periodontist– A dentist who treats diseases of the gums.
Permanent teeth– The teeth that erupt after primary teeth fall off. Also called adult teeth.
Plaque – A sticky deposit on teeth in which bacteria proliferate.
Posterior teeth – The bicuspids and molars. Also called the back teeth.
Primary teeth– A person’s first set of teeth. Also called baby teeth or temporary teeth.
Prophylaxis – The act of cleaning the teeth to prevent teeth and gum disease.
Prosthodontics – The field of dentistry that deals with artificial dental appliances.
Pulp – The inner tissues of the tooth containing blood, nerves and connective tissue.
Receding gum – A condition in which the gums separate from the tooth, allowing bacteria and other substances to attack the tooth’s enamel and surrounding bone.
Resin filling – An artificial filling used to restore teeth. Also called a composite filling.
Root canal treatment– A procedure in which a tooth’s nerve is removed and the inner canal cleansed and filled.
Root planing – Scraping or cleansing of teeth to remove heavy buildup of tartar below the gum line.
Sealant– Dental sealants are plastic coatings that are usually placed on the chewing (occlusal) surface of the permanent back teeth — the molars and premolars — to help protect them from decay. Toothbrushes can’t reach all the way into the depressions and grooves to extract all food and plaque. While fluoride helps prevent decay and helps protect all the surfaces of the teeth, dental sealants add extra protection for the grooved and pitted areas.
TMJ– Temporomandibular joint disorder. Health problems related to the jaw joint just in front of the ear.
Tartar– A hardened substance (also called calculus) that sticks to the tooth’s surface.
Veneer– A laminate applied or bonded to the tooth.
