Root
Canal Therapy (Endodontics)
A
root canal is something that we don't mind as long as it is happening
to someone else. Root canal therapy has existed for centuries
and actually was first performed in ancient civilizations - most
often only the nobility and very wealthy were treated.
There
is the old tale about the tooth becoming "dead" once
the nerve is removed. This is simply not true. The blood supply
in the tissues that support the tooth in the jaw give all the
nourishment the tooth requires. Biting pressure remains normal
although there is no response to hot, cold or sweets. There is
a 95% + chance that you'll retain a tooth that has had root canal
therapy.
Some
indications for a root canal are:
| |
Pain
while biting. |
| |
Sensitivity
to hot or cold. |
| |
Deep
decay. |
| |
Blunt
injury to the tooth. |
| |
Infection |
When
the pulp or "nerve center" of a tooth becomes unhealthy,
two alternative treatments are available: extraction or root
canal therapy.
Root
canal therapy permits the tooth to be retained and restores
its health so that it can function normally and look natural.
| CROWN
- this is the part of the tooth you can see above the gumline. |
 |
| ROOT
- this part of the tooth sits in the bone below the gum.
The root of your tooth is usually twice as long as the crown,
the part you see above the gumline. |
| BONE
- the roots of your teeth are anchored by bone.Healthy teeth
stimulate and keep bone tissue healthy. |
| PERIODONTAL
LIGAMENT - like the springs that hold a trampoline to
its frame, this tissue supports the tooth and holds it in
place in the bony socket surrounding the tooth.This tissue
cushions both the tooth and the surrounding bone against
the shock of chewing and biting. |
GUM
- We call this the "gingiva." It covers the bone surrounding
your teeth. When you brush your teeth after meals and floss
daily, you keep this tissue healthy. That's important, because
gum disease can cause bone loss. Gum disease can also expose
the tooth roots to decay. If root decay affects the pulp, you
may need root canal treatment.

The
tooth is not a solid object, but rather has a space in its center.
Each tooth has a soft tissue (the pulp) in this space. This
tissue partially nourishes the tooth from the inside. Because
of deep decay, injury, or gum disease, the tissue in your tooth
has become inflammed or infected (diseased). In any other part
of your body, if a similar tissue becomes diseased, the body
merely throws it off and forms new tissue. However, every tooth
is unique and different situation. Because the soft tissue within
the tooth is totally encased within hard tissue, the body cannot
get to it in order to affect repair. Therefore, it is the role
of the dental professional to do what the body is unable to
do. He must remove the soft tissue located in the internal spaces(canals),
cleanse the area, and finally fill the canals with a special
material so that bacteria cannot re-enter the tooth to cause
another infection. When the endodontic treatment is complete,
the tooth is by no means "dead". It receives quite
adequate support from the surrounding tissues and may be expected
to last as long as any other natural tooth.

STEP
1
After the tooth is anesthetized, an opening
is made through the crown into the pulp chamber
|
| |
STEP
2
The length of the root canals is determined |
| |
STEP
3
Unhealthy pulp is removed. Canals are
cleaned, enlarged and shaped. |
| |
STEP
4
Canals are filled and sealed. A metal post may be added
for structural support or to retain restorative materials.
|
| |
STEP
5
The tooth is sealed with a temporary filling.
Usually a crown adds further protection. |

ASKED QUESTIONS ABOUT RCT
Nothing
is as good as a natural tooth! And sometimes your natural tooth
may need endodontic (root canal) treatment for it to remain a
healthy part of your mouth.Most patients report that having endodontic
(root canal) treatment today is as unremarkable as having a cavity
filled. If you've been told you need endodontic (root canal)treatment,
you can find the answers to your questions below.
Who
performs endodontic treatment?
All
dentists, including your general dentist, received training in
endodontics while in dental school.
Why
is there a need for endodontic treatment?
Sometimes
the pulp inside your tooth becomes inflamed or infected. This
can be caused by deep decay, repeated dental procedures on the
tooth, a crack or chip in the tooth, or a blow to the tooth.
What
are the signs of needing endodontic treatment?
Signs
to look for include pain, prolonged sensitivity to heat or cold,
discoloration of the tooth, and swelling and tenderness in the
nearby gums. But sometimes, there are no symptoms.
How
does endodontic treatment save the tooth?
Dr.
Peoples and Dr. Castleberry will remove the inflamed or infected
pulp, carefully cleans and shapes the inside of the tooth, then
fills and seals the space. Afterwards,he will place a crown or
other restoration on the tooth to protect it and restore it to
full function.
Will
I feel pain during or after the procedure?
While
many patients may be in great pain before seeing a dental professional,
most report that the pain is relieved by the treatment and that
they are comfortable during the procedure. For the first few days
after treatment, the tooth may feel sensitive, especially if there
was pain or infection before the procedure. This discomfort can
be relieved with medications. The dentist will tell you how to
care for your tooth at home.
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, because it could fracture. Otherwise, just practice
good oral hygiene - brushing, flossing and regular checkups and
cleanings. Endodontically treated teeth can last for many years,
even a lifetime.
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, we may discover
very narrow or curved canals that could not be treated during
the initial procedure.
