Root Canal Gallery
If the nerve of a tooth gets infected, it can be extremely painful. The goal of root canal treatment is to relieve pain, and restore your smile!
A root canal procedure involves removing diseased tissues (indicated by the yellow arrow), which contain the nerve and blood supply of a tooth, and replacing it with a rubber-type material. The area that is filled is called the “root canal.”
Root Canal Gallery Case
Some canals are very wide, similar to this x-ray of a front tooth. Most of the canals, where the nerve and blood vessels of the tooth reside, are narrow like the wick of a candle.This means there is less tooth structure surrounding the canal, which can indicate that the tooth is weaker.
The tooth on the right is what we typically expect to see in regard to a normal root canal anatomy. His tooth has three separate canals. The tooth on the left has only a single canal, which is why the filling material appears so wide. The internal anatomy of each tooth is different, which makes each root canal procedure unique.
This x-ray was taken approximately one year after the root canal treatment. Notice that the dark area has filled in with bone, indicating that the root canal was successful. The large white area on the top portion of the tooth is a crown, which is required treatment for almost all back teeth that have a root canal.
This is an x-ray of a back tooth, known as a molar. Which was taken immediately after root canal treatment. The arrow is pointing to a dark area, where there is an infection.
The dark area around the entire root of the tooth above indicates the presence of a large infection.
Conventional root canal treatment Was performed and this is an x-ray of the tooth about six months later. You can see the dark infected area has disappeared and has been replaced by healthy bone structure. The prognosis for this tooth is excellent.
This is an x-ray of an upper front tooth. The root on this tooth is shorter than normal. The cells of the root of the tooth are being eaten away in a process that is called external resorption. This process usually occurs very slowly over a several months or years and is usually associated with some sort of trauma to the tooth.
This tooth has an “accessory canal,” which is a canal that splinters off in an unexpected direction This tooth had to be retreated due to the first root canal failing, which is evident by the dark area, which is where the arrow is pointing. Upon re-treatment, the accessory canal was found and filled, and the prognosis for this tooth is good.
This procedure is a last attempt at saving the tooth. The success of this procedure depends upon when the resorption is diagnosed and treated, the length of the root of the tooth, and the health of the surrounding bone. In the case above, both teeth showed signs of resorption, which is why they were each treated with a root canal.
This is a different tooth that also had an accessory canal, in the area indicated by the red arrow. The prognosis for this tooth is also good, but as with most root canals, a periodic exam and x-ray are needed to monitor for any issues.
The yellow arrow above indicates internal resorption. This occurs when the cells inside the tooth destroy the root from the inside out. This process usually happens very slowly over a matter of months or years and is usually associated with some sort of trauma to the tooth.
The treatment for internal resorption usually takes up to two appts. First, a medicated filling is placed and then, after a few weeks, the medicated filling is removed and the procedure is completed in the conventional way. This type of condition requires annual examination by x-ray to check on the tooth.
The root canal of each tooth is very different. The reason this tooth needed a root canal was due to decay (indicated by the white arrow) entering the pulp.
This is what the completed root canal looks like on an x-ray. This tooth had three canals, which you can see by the white filling material in the root portion of the tooth.
This is an example of a back tooth that developed a cyst A root canal was performed and you can see some of the root canal filling material in the dark area, which represents an accessory canal. The prognosis for this tooth is good because the accessory canal was found and filled.
This is another example of an accessory canal in a back tooth.This canal,by the red arrow, was rather large. The prognosis for this tooth is also good because the accessory canal was found and filled.
This is an x-ray of an upper molar with four canals, which is not very common. What makes the treatment of this tooth more difficult is the curvy nature of its canals.
The four canals have been labeled on this x-ray. Canal #1 is very straight but the other three canals, especially #3, are curved. Each canal must be free of any nerve or blood tissue before it is filled to ensure a good prognosis.
