Root canal treatment is the removal of the tooth’s pulp, a small thread-like tissue in the centre of the tooth.
Once the pulp is damaged, infected or dead it should be immediately removed and the remaining space should be cleaned,
reshaped and filled in. Years ago, a diseased tooth or a tooth with injured pulps should be entirely removed.
Nowadays, the root canal treatment saves a lot of teeth that would otherwise have been lost.
Why is it necessary?
The root canal treatment is necessary when the dental pulp of a tooth is irritated or infected. An infected pulp is most commonly caused by deep decay, a tooth that has undergone repetitive dental treatments or is fractured. In addition to this, a blow to the tooth can damage the pulp, even if the tooth has no visible cracks or fractures. Bacteria found in the mouth as normal microbial flora, can seep in the pulp, leading to the death of the nerve and to an inevitable contamination, which will spread to the root and reach the bone, causing thus great damage to the bone that surrounds the tooth. The pressure caused by the infection causes excruciating pain. If the tooth is left with no treatment, in extreme cases, it can be a threat to the patient’s life.
A lot of patients are worried about the treatment mostly because of other people’s experiences or of their own painful scenarios.
However, you might be surprised to find out that this treatment is absolutely comfortable and painless.
During the first session an aesthetic is applied to the area concerned so that the area is completely numb and isolated from the rest of the mouth. This is also done to keep the teeth clean and dry during the procedure. To clean the infected area within the tooth, a small opening is made on the top of the tooth. Once we find the pulp chamber, we remove the infected tissue with the help of tiny tools. After that tissue is removed the root canals are cleaned and formed to the desired length and height. This is done with the help of a digital device which measures the length of the root canals and is double checked with the help of X-rays before the tooth is temporarily closed.
During the second session, the temporary filling is removed and the root canals are cleaned again to ensure that no infected tissue is left behind. After they are dry, we insert once again the laser for a final sterilization. Then, we fill the canals with a rubber-like biocompatible material called gutta percha. We use a temporary filling to seal the tooth until its final restoration.
The dental laser kills the bacteria present in the root canals , created by infections or nerve necrosis. In this way, the possibilities of the creation of an abscess or a cyst are eliminated. In case there is a cyst or an infection on the bottom of the root, then directly via the root and with no surgical intervention, the laser address the problem.
A tooth that has undergone an periodontic treatment is brittle and will most probably break and lead to the loss of the tooth. For this reason,
these teeth must be replaced. If the denervated tooth does not have enough dental substance to sustain any restoration, then screw posts is the only solution.
The screw posts are place inside the tooth and the filling material will be placed on the screw post.
This post screw, together with the restoration, provide the tooth enough support and maintain the shape of the tooth so that a porcelain bridge can be positioned . Once the denervation is over, special tools are used to create a part of the root canal, which is already filled with a rubber-like material. When that part is clean and
dry, we choose a post screw made of metal, reinforced fibre or carbon fibre and we stick it on the canal. Once the screw is properly positioned, we create the teeth with the appropriate reconstruction material and we leave it solidify. When this process is over, we form the tooth and prepare it to accept the crown that will be positioned on top of it.
