What is Root canal treatment ?

The process where infected nerves that form on the
dental canals as a result of loss of liveliness of
nerves and veins of teeth that appear due to the
fractures and cracks on teeth, decays on teeth or
wrong treatment processes, are cleaned, disinfected
and filled with canal filling materials is named as
root canal treatment.

When is root canal treatment required?


  • For decays that have advanced till the toothnerve,
  • In cases where fractures occur including
tooth nerve, as a result of trauma,
  • In cases where tooth losses its liveliness as
a result of extreme pressure on tooth due to
orthodontics treatment,
  •  In advanced gingiva diseases,
  • In relieving the sensitivity arising due to
extreme abrasion on teeth,
  • In prosthesis or fillings that are realized as
being high.

How do you understand that root canal treatment is
necessary for a tooth?

In below cases, it is understood that treatment is needed:


  • Cold and warmth sensitivity on your tooth,
  • Feeling of pain without any stimulant
during night time,
  • Feeling of pain while eating
  • Change of color on teeth due to dying of
  • Swelling on face due to apsis formation,
  • During dental and radiological exami-
nations made with no signs in some cases

What are the stages of root canal treatment?


  •  First of all, it is enabled for you not to feel
any pain with the anesthesia applied.
  • Decays are cleaned or broken part is
removed and it is reached to tooth nerves.
  •  Nerves and tissues at the root of tooth are
  •  Root canal is shaped till root edge.
  •  Depending on situation of tooth, either
treatment with one session or a few
sessions can be made.
  • During session breaks, medical dressing is
applied with drugs that would recover root
edge and interior part.
  • At the final stage of root canal treatment,
interior part of canal is filled with a special
filling material till the root edge.

What are the particulars to pay attention to during
root canal treatment?

Until the influence of anesthesia ends, nothing
should be eaten or drank.
During the treatment, dried nuts or other similar
hard food should not be eaten and it should be
avoided to chew gums. Most dental fractures occur
between the sessions.
Attention should be paid for the temporary filling
not to fall down between treatment sessions.

Is root canal treatment a painful process?

As anesthesia will be applied during root canal
treatment, patient doesn't feel any pain.

Will there be pain after root canal treatment?

After the treatment, there can be slight pain and
sensitivity on tooth especially while chewing.
There won't be any problems with using a light
anti-inflammatory drug after the treatment for a
few days.

Is it required to extract the tooth due to the
inflammation that forms on tooth ?

Nowadays, due to the materials and techniques
used in root canal treatment, majority of abscess at root edge can be treated and thus, it is not
required to extract the tooth.

Is it required to use antibiotics in dental

Under normal conditions, it is not required to use
antibiotics in root canal treatment. However, if there is
advanced infection or extreme sensitivity on tooth,
antibiotics could be given.

Is root canal filling and filling different processes?

Root canal filling is the process of cleaning and filling
the root canal. Filling process is the restoration of
crown part of tooth in the mouth that is visible,
with composite filling, inlay, onlay or crown
depending on the level of damage.

Are teeth undergoing root canal treatment more

As tooth losses its liveliness as a result of canal
treatment, it gets more fragile. As there is too much
loss of material on teeth and as they get more
fragile as a result of root canal treatment, after treatment
dental veneers should be preferred.

What is repetition of root canal treatment?

Success rate of root canal treatments which are realized
under sterile conditions in a correct way is between
%90 - 95. If any uncleaned nerve tissue remains
during treatment and in cases where root canal
filling and upper filling are not realized
sufficiently, as microorganisms enter the canal,
and as perforation occurs or fractures are seen, it
can be mentioned that root root canal treatment is
unsuccessful. An unsuccessful root canal treatment
could be noticed by the feeling of pain on
teeth while eating, spontaneous pain, swelling or
redness on root edge. By renewing the unsuccessful
root canal treatment, the therapy is repeated. If this
process is insufficient, by applying apicoectomy,
root edge is reached surgically and infection is
cleaned and it is closed. If repeating the canal
treatment and the surgical intervention are
insufficient, it can be needed to extract the tooth.
