Root Canal Therapy
Years ago, a badly infected, painful
tooth, or one that had significant decay, was doomed to be
extracted. Today, a majority of these teeth can be salvaged
by a special dental procedure called Root Canal Therapy.
INDICATIONS
A Root Canal Treatment is needed when a tooth’s
nerve and associated blood vessels are irreversibly damaged.
For example:
- Tooth
damaged by trauma.
- A
fractured tooth.
- Deep
cavity that has infected the nerve.
The end result is the same – an
infection that leads to an abscess at the base of the tooth.
SIGNS
AND SYMPTOMS
- Throbbing
pain in the tooth (especially noticeable when lying horizontal,
i .e . in bed at night).
- There
may also be a swelling in your jaw.
- The
tooth may be painful to chew on.
- Pain
on consuming hot and/ or cold foods.
- Teeth
that are severely worn out.
Your tooth can usually be saved at this
Time
A
Dentist can save a tooth by removing the diseased nerve tissue,
cleaning and then filling the nerve chamber. A root canal
is a relatively simple procedure with little or no discomfort
involving one to four or more visits. Best of all, it can
save your tooth and your smile. The Treated tooth usually
can function like a normal tooth after Root Canal Therapy.
Extraction is truly the last resort.
Your Dentist Can Help
Your Dentist can assess the extent
of damage by a comprehensive dental examination. Your Dentist
takes a dental history, examines your teeth and gums, and
X-ray your teeth. X-rays allow your Dentist to see the inside
of your teeth and the surrounding bone.
Understanding your teeth may help take
the mystery out of Root Canal Therapy for you.
Unhealthy Tooth
Bacteria can invade your tooth through a loose
filling, a cavity or a crack. Your pulp becomes infected as
it is attacked by bacteria may destroy the pulp. At this stage
there may or may not be any symptoms. A Root Canal Treatment
would usually save this tooth.
If left untreated, the infection may even
spread to your bone (abscess).
Why do I need Root Canal Treatment?
Without treatment, infection will spread,
bone around the tooth will degenerate and the tooth may fall
out. Pain usually increases until one is forced to seek emergency
dental attention. The only alternative now is usually extraction
of the tooth, which can cause surrounding teeth to shift and
weaken. Though an extraction is cheaper, an implant or a bridge
to replace the tooth can be more expensive than Root Canal
Therapy. If you have a choice, it is always advisable to keep
your original teeth. However, there are limitations, and be
possible. Allow your dentist to decide.
What is involved in Root Canal Therapy?
- Your
treatment may take one or more visits, where the nerve of
the offending tooth is removed and the root canal is subsequently
filled.
- You
may receive local anaesthesia.
- Your
dentist may take x-rays to ensure that the full length of
your root canal is treated.
- If
your roots are unusually shaped or there are other complications,
you may need to have apical
surgery (Apicoectomy) as advised by your Dentist.
PROCEDURE:
Step1: The
tooth is anaesthetized and an opening is made through the
crown into the pulp chamber.
Step2: The
length of the root canals is determined. Unhealthy pulp is
removed. The canals are cleaned, enlarged and shaped with
special root canal files and disinfecting solutions.
Step3:
Once the tooth is free of infection, the tooth is filled
with a special Root Canal Filling material like gutta percha
and sealed with a temporary filling.
Step4:
A post and cure be added for structural support. Usually
a metal or porcelain crown is made for the tooth to provide
further protection.
Do children require Root Canal Therapy?
Yes. Very often milk and permanent
teeth in children may require Root Canal Therapy, though the
procedure varies slightly in milk teeth.
What happens after Treatment?
After the inside of your tooth has been treated,
the outside will be restored to protect your tooth’s underlying
structures and give your tooth a healthy appearance. After
Root Canal Therapy your tooth should function and feel like
your other teeth. Take care of your treated tooth the same
way you would your other teeth. Brush and floss regularly.
It
is advisable to visit your Dentist regularly for preventive
check- ups. Your Dentist is trained to see hidden problems
that you cannot.
