tennurnar

Tennurnar is the Icelandic term for the set of human teeth. The word tönn means a tooth, and tennurnar is the definite plural form meaning "the teeth." In clinical contexts it is used to refer to the human dentition, while in everyday language it can describe a person’s teeth collectively.

Teeth are calcified structures anchored in the upper and lower jaws. Each tooth has a crown above the gum line and one or more roots below. The enamel is the hard outer layer, dentin forms the bulk of the tooth, and the pulp contains nerves and blood vessels. Teeth perform cutting and grinding, contribute to digestion, aid in speech, and shape facial appearance.

There are four main types: incisors for cutting, canines for tearing, premolars for tearing and crushing, and molars for grinding. In a typical adult dentition there are 32 teeth, including wisdom teeth that may be absent or removed. Children develop 20 primary teeth that are later replaced by the permanent set, usually beginning around age six and completing in adolescence.

Maintaining Tennurnar involves daily brushing with fluoride toothpaste, interdental cleaning, limited sugary foods, and regular visits to a dental professional for examinations and cleanings. Common issues include dental caries (cavities), gum disease, tooth loss, and enamel wear. Good dental care supports overall health and well-being.
