Plaque forms on all surfaces of the teeth. It is a layer of bacteria. Often the part of the tooth closest to the gum isn't cleaned properly and the plaque stay there. It will continue to grow into a thick layer, while it consumes the carbohydrates (eg sugar, starch etc) and then makes acid. This acid can inflame the gums. Plaque can be removed using a toothbrush or floss. Mouthwash will not remove plaque.
Conversely, if plaque sits on teeth for too long in certain parts of the mouth with lots of saliva, that plaque can mineralise and become a cement-like layer called 'Calculus' or also known at 'Tartar'. This is a rough surface that harbours more plaque and can irritate the surrounding tissue. Calculus/Tartar cannot be removed with a toothbrush/floss. A dental professional will have to remove this build-up.
The hardened deposits that form on the teeth and can irritate the surrounding tissue, is called tartar or dental calculus. If good oral hygeine is not practiced, tartar can build up on the teeth and become hardened. This can irritate the gums and cause them to bleed.
The tissue that supports the teeth are the bones of the jaw and the ligaments that hold the teeth in place.
Pericoronal tissue is the tissue surrounding the crown of a partially erupted tooth, particularly the third molars (wisdom teeth). It can become inflamed or infected if bacteria get trapped beneath the gum flap covering the partially erupted tooth.
Dentin is the major tissue composing teeth and is covered by enamel.
Gum...within the mouth the soft tissue surrounding the teeth, commonly referred to in the plural, i.e. 'Gums'...
The fringe of pointed teeth surrounding a moss capsule is known as the peristome. It helps regulate the release of spores from the capsule by responding to changes in humidity and moisture levels. The teeth can open and close to control spore dispersal, aiding in the moss's reproductive process.
A living cell is the smallest structure of that carries out specific functions.
Depending on what exact part the inflammation is in: 1-Periodontitis is a set of inflammatory diseases affecting the peridontium, that is, the tissues that surround and support the teeth. 2-Gingivitis: inflammation of the gum tissue. 3-Pericoronitis: inflammation of the soft and hard tissues surrounding one particular tooth (e.g. wisdom tooth)
The teeth are supported by the jaw bones, specifically the maxilla (upper jaw) and mandible (lower jaw). These bones provide the structure and foundation for the teeth to attach to, as well as support the surrounding soft tissues such as gums and muscles.

Gums are the pink tissue that surround the teeth and covers the alveolar. The function of the gums is to protect the teeth and support the mouth's structure.
The tissue behind and between the upper two front teeth is called the incisive papilla.
