Periodontal
Disease and Tooth
Loss
Gingivitis
is the low-grade inflammation of the gums due to the presence of
plaque bacteria.
Chronic periodontitis is the main cause of tooth loss in late
adulthood. The periodontal ligaments holding the tooth in its socket
are destroyed and the alveolar crests are resorbed. The level of
alveolar resorption can be measured to determine how long the
individual has had the disease.
When there is poor oral hygiene, a person with cardiac trouble can
develop infective endocarditis due to circulating bacteria in the
bloodstream.

After anti-mortem tooth loss, the
alveolar bone surrounding the lost tooth is resorbed. If a tooth is
lost after death, the tooth socket will still be present. This is
important to the anthropologist trying to put together a life history.
Extractions have likely been practiced for thousands of years. It was
an important development in improving oral health. Records
of this have been found in ancient Mesopotamia.
