Q What is root canal treatment?
A Root
canal treatment (also called endodontics) is needed
when the blood or nerve supply of the tooth (known
as the pulp) is infected through decay or injury.
Q Why is root canal treatment needed?
A If
the pulp becomes infected, the infection may spread
through the root canal system of the tooth. This
may eventually lead to an abscess.
If root canal
treatment (RCT) is not carried out, the infection
will spread and the tooth may need to be taken
out.
Q Does it hurt?
A No. A
local anaesthetic is used and it should feel no
different to having an ordinary filling done.
Q What does it involve?
A The
aim of the treatment is to remove all infection
from the root canal. The root is then cleaned
and filled to prevent any further infection.
Root canal treatment
is a skilled and time-consuming procedure. Most
courses of treatment will involve two or more visits
to your dentist.
At the first appointment, the infected pulp is
removed. Any abscesses, which may be present,
can also be drained at this time. The root
canal is then cleaned and shaped ready for the
filling. A temporary filling is put in and
the tooth is left to settle.
The tooth is
checked at a later visit and when all the infection
has cleared, the tooth is permanently filled.
Q What will my tooth look like after treatment?
A In
the past, a root filled tooth would often darken
after treatment. However, with modern techniques
this does not usually happen. If there is
any discolouration, there are several treatments
available to restore the natural appearance.
Q What if it happens again?
A Root
canal treatment is usually very successful. However,
if the infection comes back the treatment can be
repeated.
Q Is it expensive?
A You
can have root canal treatment on the National Health
Service. However, due to the time it takes
and the skill needed, many dentists prefer to carry
out this treatment privately. Your dentist
will be pleased to give you an estimate.
Q What if I don’t have the treatment?
A The
alternative is to have the tooth out. Once
the pulp is destroyed, it can’t heal and
it is not recommended to leave an infected tooth
in the mouth.
Although some
people would prefer an extraction, it is usually
best to keep as many natural teeth as possible.
Q Will the tooth be safe after treatment?
A Yes. However,
it is better to restore the tooth with a crown
to provide extra support and strength to the tooth.
Q Where can this treatment be carried out?
A Root
canal treatment is a routine dental procedure,
which your dentist will be happy to do for you.
Q What about aftercare?
A Root-treated
teeth should be treated just the same as any other
tooth. Remember to clean your teeth at least
once a day, preferably with a fluoride toothpaste. Cut
down on sugary snacks, and keep them only to mealtimes
if possible. See your dentist for regular
check-ups.
