When teeth are
severely worn, it is necessary to replace the structure that has
been worn away with an artificial material, which is at least as
hard as the missing enamel. The two materials best suited for this
are gold alloys and porcelain. The gold used to restore teeth ranges
from 10 to 18 carat gold depending on the application. Gold of greater
purity is too soft to resist new wear. Often porcelain is used to
cover the gold to make the restoration appear lifelike. When the
enamel of a tooth is worn away, the tooth often becomes sensitive
and is more susceptible to decay. Advanced cases often require crowns
to save the teeth.
One or more of the following factors may cause premature wear:
Attrition It
is the most common cause of enamel "wear." Normal speaking
and eating may cause a small amount of attrition, but this typically
doesn't produce excessive wear. More extreme cases of attrition
are typically caused by Bruxism, the grinding of teeth against teeth.
Often the patient does the teeth grinding at night while he sleeps.
The patient is often unaware of the grinding.
Abrasion
Abrasion is the wearing away of tooth enamel by a foreign object.
Common causes of abrasion are:
Brushing too hard or too long
Fingernail biting; chewing on pens or pencils; holding needles
or pins between the teeth; etc.
Oral jewelry - Patients with pierced lips and/or tongue
often wear away the enamel on adjacent teeth
Erosion Erosion
occurs across the whole tooth surface and does not involve bacteria
or dietary sugars, but is the result of direct action of acids on
tooth enamel (tooth hard tissues). Erosion is the chemical wear
of tooth enamel. Typically an acid causes this kind of wear. Citric
acid is one of the most common agents found in citrus fruit, juices
(lemonades), and soft drinks. Many soft drinks contain additional
harmful acids. Coffee and tea also contain corrosive acids. Bulimic
individuals expose their teeth to very strong stomach acids. Occasional
exposure to it may not be the cause. Try to rinse your mouth with
fresh water every time after you finish eating.
