If rampant caries is a result of previous radiation to the head and neck, it may be described as radiation-induced caries. Problems can also be caused by the self-destruction of roots and whole tooth resorption when new teeth erupt or later from unknown causes. Children at 6–12 months are at increased risk of developing dental caries. [99]
This diminishes the strength of the tooth which is called demineralization. For the outer layer of the tooth to reach cavitation, there is a breakdown of the enamel structure that allows the influx of the cariogenic bacteria. As cavitation progresses into dentine, the dental caries lesion becomes more severe, and this may cause tooth pain.
Toothache may be caused by dental (odontogenic) conditions (such as those involving the dentin-pulp complex or periodontium), or by non-dental (non-odontogenic) conditions (such as maxillary sinusitis or angina pectoris). There are many possible non-dental causes, but the vast majority of toothache is dental in origin. [10]
Turner's hypoplasia or Turner's tooth is a presentation of enamel hypoplasia that normally affects only a single tooth. Its causes can be the same as other forms of enamel hypoplasia, but it is most commonly associated with trauma to a primary maxillary central incisor and the subsequent developmental disturbance of the underlying permanent ...
Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially erupted tooth, [1] including the gingiva (gums) and the dental follicle. [2] The soft tissue covering a partially erupted tooth is known as an operculum, an area which can be difficult to access with normal oral hygiene methods.
This leads to an inflammatory process that causes external root resorption. [16] Alternatively, pressure may also cause external inflammatory root resorption. Specifically, application of heavy, continuous, and intrusive (i.e. directed toward the bone) forces during orthodontic tooth movement are associated with external root resorption. [17]
Plaque accumulation causes the gingiva to become irritated and inflamed, and this is referred to as gingivitis. When the gingiva become so irritated that there is a loss of the connective tissue fibers that attach the gums to the teeth and bone that surrounds the tooth, this is known as periodontitis.
The adult tooth will dissolve the baby tooth's root, making the baby tooth loose until it falls out. [8] During this stage, permanent third molars (also called "wisdom teeth") are frequently extracted because of decay, pain or impactions. The main reasons for tooth loss are decay or periodontal disease. [21]
