Do you have a tooth ache? Are your teeth sensitive to hot or cold? Does the discomfort worsen at night? Any of these symptoms are a potential indications of nerve damage in your tooth. The nerve space inside a tooth can provide a nice cozy cave-like location for bacteria to persist because it’s a place where your body’s defense mechanisms can’t get at them effectively.
With this scenario, at best your body will only be able to ward off the infection caused by the bacteria living inside your tooth. At worst, this bacterial infection will overwhelm your body’s defense mechanisms and pain and swelling will develop. If this condition is neglected it can cause a large abscess, which can in-turn lead to very severe consequences such as jaw bone destruction, airway construction, sinus infection, etc.
In a nutshell, the process of root canal treatment first removes the bacteria, nerve tissue, and bacterial toxins from within the inner aspects of a tooth. Subsequently, once this space has been cleansed the second half of root canal treatment involves filling in and sealing up the interior of the tooth. This aspect of the treatment is an attempt to minimize the possibility that bacteria will be able to re-colonize the inner aspects of the tooth.

Can Root Canal Therapy help relieve my dental pain, and what exactly does the treatment involve?
Teeth that are deeply cracked, heavily restored, or severely decayed may develop inflammation and infection. Root canal treatment may be necessary to save them.
Infectious microorganisms usually enter the tooth through a leaky dental restoration, such as a crown or large filling, a fissure, tooth decay, or, occasionally, through an exposed tooth root. Once in the jawbone, these microorganisms can cause swelling and significant discomfort.
Root canal therapy removes the microorganisms and seals the tooth against future bacterial invasion.
A rubber safety dam is placed. A high-speed dental handpiece is used to gain access to the tooth for the instruments used to treat the infection.
To clean, shape, and enlarge the hollow root canals where microorganisms have settled, a series of specialized instruments are used.
Disinfectant solutions are used to flush out the micro-organisms and to lubricate the shaping instruments. The goal is to remove all of the infected tooth structure and to widen the canals to such an extent that the root canal filling materials can be easily placed in the canals.
Once the root canals have been shaped and completely irrigated, absorbent paper points are used to dry the canals.
The root canals are filled with rubber points. The points are coated with sealing cement for a hermetic seal. Rubber points are packed into root canals and melted.
Sometimes, if needed to strengthen the core of the tooth, the dentist will enlarge one or more of the sealed canals to make room for the placement of structural posts. The posts typically extend to within five millimeters of the root tips of the root, which are now sealed. The tooth access hole is filled and the posts are cemented into the canal.
What is internal bleaching and how does it work?
Teeth with nonviable or “necrotic” pulp tissue following trauma or dental disease are often noticeably darkened by pigments that saturate the dentin layer of the tooth and are visible through the translucent enamel of the crown. This is cosmetically unappealing to many people.
Of greater concern is the fact that the hollow interior of the tooth no longer contains any living cells, is open to the inside of the body, and will often become infected at some point.
To keep infectious organisms out, such teeth are usually treated with endodontic or “root canal” therapy.
After that, it is common to whiten the inside of the crown to a more normal shade.
The process involves cleaning, enlarging, and filling the root canals with a rubbery orange material called gutta-percha. The root canal fillings are then covered with a sealant. The sealant prevents bleach from seeping past the root canal fillings. A bleach-soaked cotton pellet is inserted into the crown’s hollow pulp chamber, and the tooth cavity is filled with a temporary filling. Over a period of days, the bleaching solution whitens the dentin layer of the tooth back to its normal shade. The cotton pellet is removed and a permanent filling is applied when the process is complete.
For teeth that are visible in the smile, toward the front of the mouth, internal bleaching is much more common. Often these teeth do not have a need for a crown after root canal treatment has been completed.
Molar teeth often require a crown after root canal treatment to prevent them from fracturing. If this is the case, they usually won’t be bleached because the crown can be made as light as it needs to be in the lab.
