general dental practice – This is the type of dental practice that most patients seek to provide for their basic preventive and restorative needs.
gingiva – Also known as the gums.
gingival margin – The edge of the gingiva that touches the tooth. It is usually right at the crown of the tooth.
gingival recession – Sometime due to disease processes or aggressive brushing. The gingiva recedes from the crown of the tooth and portions of the root can be seen.
gingival sulcus – A small ditch-like area between the tooth and gingiva that surrounds the entire tooth. It is only attached to the tooth at its base. It is normally between 1 and 3 mm deep.
gingivitis – An inflammation of the gingiva usually due to retention of plaque/biofilm in the area caused by poor oral hygiene.
hydroxyapatite – What the dental profession refers to as the tooth mineral.
hypersensitivity – Extreme sensitivity (usually pain) in the teeth, often due to hot, cold or sweet exposure.
implant – Permanent replacement appliance in the oral cavity for a single tooth, multiple teeth or a whole arch. It is composed of an implanted base onto which a crown, bridge or full denture is permanently attached.
in vitro – Laboratory tests that are performed outside of the living organism. It is usually done in a test tube or culture dish.
in vivo – Tests that are performed inside a living organism, such as in a human.
incisal edge – The biting edge of anterior teeth.
incisors – The four anterior teeth on both the maxilla and mandible. There are two on either side of the midline.
inflammation – The body’s immune response to harmful stimuli. The signs of inflammation are pain, swelling, redness and heat in the tissue.
interdental papillae – The gingiva tissue in between each tooth. It typically fills the area between the adjacent teeth and prevents food impaction.
interproximal – The area between two adjacent teeth.
intrinsic stain (endogenous) – Stain that is incorporated within the tooth structure. It can be due to drugs, hyper-fluoridation, genetics or illness during the formation of the permanent teeth.
