When the nerve and live tissue of a tooth is infected due to decay, a root canal treatment is indicated in order to clean the canals of the roots from of all the inflamed and infected tissue. This usually saves the tooth by removing the pulp, nerve tissue, and bacteria inside the tooth. Then the cleaned canals are replaced with medicated dental materials that fill the space of original pulp and nerve tissue.
Patients choose to have root canals treatment preformed when they wish to save a tooth that would otherwise have to be removed. Most patients believe that extracting the tooth is the best idea. However, removing a tooth is costly and leaves a space that may cause problems for other adjacent and opposing teeth. To avoid this problem, the removed tooth should be replaced by a dental implants, bridge, or removable partial denture, which is also costly.
Root canals performed at Advanced Gentle Dentistry of Park Slope are 90% successful and will usually last a lifetime. On occasion a tooth may have to be treated for new infections.
Once the tooth is thoroughly cleaned of all bacteria and debris, the canal is then sealed with a permanent root canal filling.The patient may need additional appointments to restore the access opening and broken or decayed part of the tooth. This may be a permanent filling, onlay, inlay, or a crown. The final restoration protects and prevents the tooth from breaking and restores the tooth to its full function. Our dentist will discuss the treatment of choice for each patient with him or her. Once the root canal treatment has finished the tooth may still be sensitive for a while. Eventually this sensitivity will subside as the inflammation inside the tooth reduces and the tooth begins to heal. If the patient practices good oral hygiene routines and regular dental visits, it will aid the life of the root canal.If problems arise after a procedure, we are of course reachable for our clients outside of office hours! In this case, we will give you an emergency number.

Root canal therapy on a tooth with an existing crown – Dr Sarji explains a common procedure.
Root canal therapy on a tooth with an existing crown – Dr Sarji explains a common procedure.This is actually a common procedure and we decided to write this article to explain the process to our patients . This often occurs when a tooth has had a previous root canal which has failed. When the first root canal was done a crown was placed over the tooth on the part that was not decayed with a post being inserted into the tooth so that the crown can be attached properly. Now that the root canal has failed and needs to be retreated the dentist is presented with a choice as to how he should progress. The dentist has two choices:
First Option - Ideally the dentist will remove the crown before he drills the access cavity, however this is not always possible. There may be the possibility that he will damage the existing structure of the tooth.
Second Option – If the dentist determines that the crown will not come off then an access caity must be drilled. In most cases the crown will be replaced although the tooth structure may have changed so it will not be possible to use it again. If the dentist has had to drill through it then this may weaken the crown. In most instances a new crown is needed as the structure and integrity of the crown will have been changed or may be compromised. The root canal could become re-infected very easily if the previous crown is used. It is almost always advisable to remove the crown therefore protecting the integrity of the crowns and allowing the root canal procedure to take place;For a dentist to remove a crown in a manner that it remains fully intact and unscathed can be very difficult if not impossible. During the attempt it's still possible that the crown will be damaged or worse yet the tooth damaged too and maybe significantly. Other reason for a crown failing is because of tooth decay at the edge of the crown where it meets the gumline. The crown obviously does not decay but the underlying tooth gets decayed. In a situation like this when it this happens, the decay quickly spreads underneath the crown. If the decay is significant there may be very little tooth structure left under the crown before the pulp (nerve) becomes destroyed by the decay. In a case like this a new crown will not fix the tooth and a root canal will be needed along with the new crown assuming we can actually save the existing tooth structure. When a dentist places a new crown on a tooth that already has had a crown it will take more work and will be more difficult to do that the first crown. This is due to the fact that the margins or edges of the crown will need to be deeper in order to cover up the area where the decay was removed after the old crown was taken off. This is often a complicated procedure but we have a lot of experience in dealing with these. Crowns are long lasting cosmetic restorations that for the most part will give a cosmetic appearance and perform a function but they will eventually wear out. Decay under the crown causes the crown to eventually fail. It is important that a dentist can detect early signs of decay at the edge of a crown. It takes a high degree of artistic skill to detect early decay on the edges of a crown. It must be replaced quickly in order to prevent a root canal or infection. Ask us when you come to see us about how you can take more care of your crowns. If you need a second opinion about a root canal needed underneath an existing crown then make an appointment to come and see us.
