Endodontics is the dental specialty dealing
with diseases of the dental pulp and its supporting structures. Although
general practice dentists can perform endodontic procedures patients are often
referred to an endodontist when the case is complicated or more
difficult than usual.

understand endodontic treatment it helps to know something about the
anatomy of a tooth. Teeth have several layers.
The outside layer a hard layer called the enamel. The enamel is supported
by an inner layer called the dentin which has at its centre a soft tissue known
as the pulp. The pulp contains blood vessels, nerves, and connective
tissue that are responsible for forming the surrounding dentin and enamel during
tooth development. The pulp receives its nourishment supply from vessels
which enter the end of the root. Although the pulp is important during
development of the tooth, it is not necessary for function of the tooth. The
tooth continues to be nourished by the tissues surrounding it even after the
pulp is removed.

treatment is necessary when the pulp becomes inflamed or
infected. The most common reasons for inflammation or infection are
deep cavities (caries), repeated dental procedures, cracks or chips.
Trauma can also cause inflammation and often shows up as discoloration of the
tooth. If pulp inflammation or infection is left untreated, it can cause
pain or lead to an abscess.
Symptoms indicating the need for treatment
include prolonged sensitivity to heat or cold, discoloration of the tooth,
swelling or tenderness of the tooth or adjacent gums. Sometimes there are
no symptoms. |
