Tooth
Pain?
If you experience prolonged tooth pain, chances are your tooth has had some kind
of trauma . Truama could be physical trauma such as falling and hitting the tooth
or simply decay that has progressed to a state that neccesitates immedite attention.
Usually, we find that the nerve has been compromised. At this point, a root canal
is recommended depending on the severity of the problem.
What Is A Root Canal?
Underneath your tooth's outer enamel and within the dentin is an area of soft
tissue called the pulp, which carries the tooth's nerves, veins, arteries and
lymph vessels. Root canals are very small, thin divisions that branch off from
the top pulp chamber down to the tip of the root. A tooth has at least one but
no more than four root canals.
Why do I feel pain?
When the pulp becomes infected due to a deep cavity or fracture that allows bacteria
to seep in, or injury due to trauma, it can die. Damaged or dead pulp causes
increased blood flow and cellular activity, and pressure cannot be relieved from
inside the tooth. Pain in the tooth is commonly felt when biting down, chewing
on it and applying hot or cold foods and drinks.
Why do I need root canal therapy?
Because the tooth will not heal by itself. Without treatment, the infection will
spread, bone around the tooth will begin to degenerate, and the tooth may fall-out.
Pain usually worsens until one is forced to seek emergency dental attention.
The only alternative is usually extraction of the tooth, which can cause surrounding
teeth to shift crookedly, resulting in a bad bite. Though an extraction is cheaper,
the space left behind will require an implant or a bridge, which can be more
expensive than root canal therapy. If you have the choice, it's always best to
keep your original teeth.
What is a root canal procedure?
A root canal is a procedure done to save the damaged or dead pulp in the root
canal of the tooth by cleaning out the diseased pulp and reshaping the canal.
The canal is filled with gutta percha, a rubberlike material, to prevent recontamination
of the tooth. The tooth is then permanently sealed with possibly a post and/or
a gold or porcelain crown. This enables patients to keep the original tooth.
What is involved in root canal therapy?
Once your general dentist performs tests on the tooth and recommends therapy,
he or she can perform the treatment or refer you to an endo-dontist (a pulp specialist).
Treatment usually involves one to three appointments.
First, you will probably be given a local anesthetic to numb the area. A rubber
sheet is then placed around the tooth to isolate it. Next, a gap is drilled from
the crown into the pulp chamber, which, along with any infected root canal, is
cleaned of all diseased pulp and reshaped. Medication may be inserted into the
area to fight bacteria. Depending on the condition of the tooth, the crown may
then be sealed temporarily to guard against recontamination, or the tooth may
be left open to drain, or the dentist may go right ahead and fill the canals.
If you're given a temporary filling, usually on the next visit it's removed and
the pulp chamber and canal(s) are filled with rubberlike gutta percha or another
material to prevent recontamination. If the tooth is still weak, a metal post
may be inserted above the canal filling to reinforce the tooth. Once filled,
the area is permanently sealed. Finally, a gold or porcelain crown is normally
placed over the tooth to strengthen its structure and improve appearance.
What are the risks and complications?
More than 95 percent of root canal treatments are successful. However, sometimes
a case needs to be redone due to diseased canal offshoots that went unnoticed
or the fracturing of a canal filing instrument used-both of which rarely occur.
Occasionally, a root canal therapy will fail altogether, marked by a return of
pain.
What happens after treatment?
Natural tissue inflammation may cause discomfort for a few days, which can be
controlled by an over-the-counter analgesic. A follow-up exam can monitor tissue
healing. From this point on, brush and floss regularly, avoid chewing hard foods
on the treated tooth, and see your dentist regularly. |
