Occlusion
Treatment to improve the action [articulation] of the teeth and chewing capability. Malocclusion (incorrect bite) can lead to serious temporo-mandibular joint problems and pain.
Odontoblast
A specialised cell that is responsible for laying down the calcified substance called dentine that surrounds and protects the pulp tissues. Odontoblasts remain active throughout life and are continually laying down new dentine during the ageing process. It gradually seals up the minute channels previously occupied by nerve fibres and reduces tooth sensitivity.
Odontome
An abnormal growth of calcified dental tissues made up of dentine and enamel. The growth will frequently remain embedded in the jaw and not give rise to any symptoms.
Oedema
The leaking of fluid [plasma] into the tissues which creates a swelling either caused by an obstruction of a blood vessel or increased cellular permeability.
Orthodontics
The dental process that straightens teeth or brings teeth into a regular arrangement [the correction of malocclusion].
In recent years orthodontic technology has improved dramatically and with the use of fixed appliances (train tracks) teeth can be moved significant distances into perfect positions.
