Endodontic Treatment
You're probably reading this because your dentist or endodontist has said
you need endodontic treatment. If so, you're not alone. More than 14 million
teeth receive endodontic treatment each year. By choosing endodontic treatment,
you are choosing to keep your natural teeth as a healthy foundation for chewing
and biting for years to come.
If you've never had endodontic treatment- also known as "a root canal"- or
if it's been many years since your last procedure, you may have questions or
outdated expectations.
This booklet answers your questions and explains how today's endodontic
treatment saves teeth. If you would like to know more, be sure to talk with
your endodontist.

Who performs endodontic treatment?
All dentists, including your general dentist, received training in endodontic
treatment in dental school. General dentists can perform endodontic procedures along
with other dental procedures, but often they refer patients needing endodontic
treatment to endodontists.
Endodontists are dentists with special training in endodontic procedures. They do
only endodontics in their practices because they are specialists. To become specialists,
they complete dental school and an additional three or more years of advanced training
in endodontics. They perform routine as well as difficult and very complex
endodontic procedures, including endodontic surgery. Endodontists are also
experienced at finding the cause of oral and facial pain that has been difficult
to diagnose.
What is endodontic treatment?
"Endo" is the Greek word for "inside" and "odont" is Greek for "tooth". Endodontic
treatment treats the inside of the tooth.
To understand endodontic treatment, it helps to know something about the anatomy
of the tooth. Inside the tooth, under the white enamel and a hard layer called the
dentin, is a soft tissue called the pulp. The pulp contains blood vessels, nerves, and
connective tissue and creates the surrounding hard tissues of the tooth during development.
The pulp extends from the crown of the tooth to the tip of the roots where it
connects to the tissues surrounding the root. The pulp is important during a
tooth's growth and development. However, once a tooth is fully mature it can survive without
the pulp, because the tooth continues to be nourished by the tissues surrounding it.
Why would I need an endodontic procedure?
Endodontic treatment is necessary when the pulp becomes inflamed or infected. The
inflamation or infection can have a variety of causes: deep decay, repeated dental
procedures on the tooth, or a crack or chip in the tooth. In addition, a blow
to a tooth may cause pulp damage even if the tooth has no visible chips or cracks.
If pulp inflammation or infection is left untreated, it can cause pain or lead to an
abscess.
Signs of pulp damage include pain, prolonged sensitivity to heat or cold, discoloration
of the tooth, and swelling and tenderness in the nearby gums. Sometimes, there are
no symptoms.
How does endodontic treatment save the tooth?
The endodontist removes the inflamed or infected pulp, carefully cleans and shapes
the inside of the tooth, then fills and seals the space. Afterwards, you will
return to your dentist, who will place a crown or other restoration on the tooth to
protect and restore it to full function. After restoration, the tooth continues
to function like any other tooth.
Will I feel pain during or after the procedure?
Many endodontic procedures are performed to relieve the pain of toothaches caused
by pulp inflammation or infection. With modern techniques and anaesthetics, most
patients report that they are comfortable during the procedure.
For the first few days after treatment, your tooth may feel sensitive, especially
if there was pain or infection before the procedure. This discomfort can be relieved with
over-the-counter or prescription medications. Follow your endodontist's instructions
carefully.
Your tooth may continue to feel slightly different from your other teeth for some time
after your endodontic treatment is completed. However, if you have severe pain
or pressure, or pain that lasts more than a few days, call your endodontist.
What is involved in an endodontic procedure?
Endodontic treatment can often be performed in one or two visits and involves
the following steps:
1. The endodontist examines and x-rays the tooth, then administers local anaesthetic.
After the tooth is numb, the endodontist places a small protective sheet called
a "dental dam" over the area to isolate the tooth and keep it clean and free of
saliva during the procedure.
2. The endodontist makes an opening in the crown of the tooth. Very small instruments
are used to clean the pulp from the pulp chamber and root canals and to shape the space
for filling.
3. After the space is cleaned and shaped, the endodontist fills the root canals with
a biocompatible material, usually a rubber-like material called "gutta-percha". The gutta-percha
is placed with an adhesive cement to ensure complete sealing of the root canals. In most
cases, a temporary filling is placed to close the opening. The temporary filling will be
removed by your dentist before the tooth is restored.
4. After the final visit with your endodontist, you must return to your dentist to have
a crown or other restoration placed on the tooth to protect and restore it to full function.
If the tooth lacks sufficient structure to hold the restoration in place, your dentist
or endodontist may place a post inside the tooth. Ask your dentist or endodontist for more
details about the specific restoration planned for your tooth.
How much will the procedure cost?
The cost varies depending on how severe the problem is and which tooth is affected.
Molars are more difficult to treat and usually cost more. Most dental insurance policies
provide coverage for endodontic treatment.
Generally, endodontic treatment and restoration of the natural tooth are less
expensive than the alternative of having the tooth extracted. An extracted tooth
must be replaced with a bridge or implant to restore chewing function and prevent
adjacent teeth from shifting. These procedures tend to cost more than endodontic
treatment and appropriate restoration.
Will the tooth need any special care or additional treatment?
You should not chew or bite on the treated tooth until you have had it restored
by your dentist. The unrestored tooth is susceptible to fracture, so you should see your dentist
for a full restoration as soon as possible. Otherwise, you need only practice good
oral hygiene, including brushing, flossing, and regular checkups and cleanings.
Most endodontically treated teeth last as long as other natural teeth. In a few cases,
a tooth that has undergone endodontic treatment fails to heal or the pain continues.
Occasionally, the tooth may become painful or diseased months or even years after
successful treatment. Often when this happens, another endodontic procedure can
save the tooth.
What causes an endodontically treated tooth to need additional treatment?
New trauma, deep decay, or a loose, cracked or broken filling can cause new infection
in your tooth. In some cases, the endodontist may discover very narrow or curved canals that
could not be treated during the initial procedure.
Can all teeth be treated endodontically?
Most teeth can be treated. Occasionally, a tooth can't be saved because the
root canals are not accessible, the root is severely fractured, the tooth doesn't
have adequate bone support, or the tooth cannot be restored. However, advances in
endodontics are making it possible to save teeth that even a few years ago would
have been lost. And, when endodontic treatment is not effective, endodontic
surgery may be able to save the tooth.
What is endodontic surgery?
The most common endodotic surgical procedure is called an apicoectomy or
root-end resection. When inflammation or infection persists in the bony area
around the end of your tooth after endodontic treatment, your endodontist may perform
an apicoectomy. In this procedure, the endodontist opens the gum tissue near the
tooth to expose the underlying bone, and the infected tissue is removed. The very
end of the root is also removed, and a small filling may be placed to seal the root
canal. Local anaesthetics make the procedure comfortable, and most patients return to
their normal activities the next day.
What are the alternatives to endodontic treatment?
When the pulp of a tooth is damaged, the only alternative to endodontic treatment
is extraction of the tooth. To restore chewing function and to prevent adjacent
teeth from shifting, the extracted tooth must be replaced with an implant or bridge. This
requires surgery or dental procedures on adjacent healthy teeth and can be far more
costly and time-consuming than endodontic treatment and restoration of the natural tooth.
No matter how effective modern tooth replacements are- and they can be very effective-
nothing is as good as a natural tooth.
