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.
