Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth) , when they are replaced by a person's adult teeth . Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion , tooth decay , and gum disease .
The loss of the permanent dentition is a multi-factorial process resulting from the impact of dental caries, periodontal disease and social factors. People who have lost teeth are referred to as (either partially or completely) edentulous (edentate), however those who have not lost teeth are referred to as dentate. [40]
It is the primary pathological cause of tooth loss in children. [151] Between 29% and 59% of adults over the age of 50 experience caries. [152] Treating dental cavities costs 5–10% of health-care budgets in industrialized countries, and can easily exceed budgets in lower-income countries. [153]
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
Tooth mobility is the horizontal or vertical displacement of a tooth beyond its normal physiological boundaries [1] around the gingival (gum) area, i.e. the medical term for a loose tooth. Tooth loss implies in loss of several orofacial structures, such as bone tissues, nerves, receptors and muscles and consequently, most orofacial functions ...

External cervical resorption is a localised resorptive lesion in the cervical area of the tooth, below the epithelial attachment. It is distinguished from external inflammatory root resorption in that it rarely involves the pulp. When at least 3 teeth are affected, it is referred to as multiple idiopathic cervical root resorption.
