A pimple or boil on the jaw. Discoloration of the tooth. Tenderness in the gum tissue near where the root canal was performed. Pain in the tooth you had treated. Presence of pus-filled abscesses near the treated tooth. Facial or neck swelling. Swelling near the affected tooth. Why Do Root Canals Fail? Traumatic dental injuries: A fracture or crack in the affected tooth can lead to infection in the root.
Root canal structure: Some patients have complex roots, such as a curved or narrow canal. You may even have more canals than the dentist anticipated. If you do feel sensitivity to hot or cold in that specific tooth, it means that a nerve has been missed. It is such a sure indicator that researchers will sometimes use thermal sensitivity as a test for re-infection pulp necrosis.
In order to recognize the symptoms of failed root canal, you should also understand the discoloration symptoms. When your dentist drills into your teeth, they are removing all the nerves. However, there will normally be a little bit of bleeding as the corrupted tissues are ground away and removed. This blood will then seep into the filler that your dentist uses to fill the tooth.
As you probably know, blood turns brown when it dries. This is why tooth discoloration is somewhat normal after a root canal treatment. The good news is that there are many ways to deal with this problem.
The obvious answer is tooth bleaching, but this method is not always effective for root canal patients. Sometimes, the filler material will be re-discolored. If your dentist did a good job of removing the corrupted material without removing anything else, there should have been minimal bleeding and thus, minimal discoloration. If your dentist is really good, they may have used a special bonding agent to prevent this problem. Research has shown that a pre-coating of dentin material is effective in reducing root canal discoloration.
Pain is a normal side effect of the root canal itself, but if it continues to plague you long after the procedure is done, you should take it as a warning. There are many ways to mitigate the pain of a toothache, but this is like putting a band-aid on an infected wound. You should be especially concerned if you experience frequent pain with no apparent cause, or if the pain grows steadily worse over time.
It may put your mind at ease to know that most root canal patients do not experience this problem. Researchers examined a total of 5, teeth. They found only that exhibited long-term pain. This means only 5. A root canal is necessary when a tooth suffers from an infection. Thus, the entire point of the procedure is to remove all traces of that infection. In most cases where a root canal has failed , it has failed because the infection was able to somehow re-establish itself. When this happens, there is no choice but to repeat the procedure.
One of the simplest and most common causes would have to be lack of sanitation. Obviously, your dentist probably tried their best to keep everything clean and sterile. However, a root canal procedure requires that the dentist keep all saliva from entering the holes that he has created. Because saliva contains a lot of bacteria , any contamination could potentially ruin the whole operation. Dentists will normally use X-rays to detect and map the nerves before they start the job. However, there is always the possibility that a nerve could be missed for one reason or another.
Defective equipment, user error, or any number of other possibilities exist. You will still have to get another root canal, but your dentist will not have to undo the earlier work.
With all the precise drilling required here, it is relatively easy for the long, thin ends of the tooth to become cracked. As you can surely imagine, this is accompanied by severe root canal pain. Sometimes, Dr. Root canals are typically performed to treat teeth that have developed damage or infection to the inner pulp. If you take proper care of your tooth that has been treated with root canal therapy, it can last a lifetime. These are all reasons that your tooth may not heal correctly or get re-infected following root canal therapy.
However, the chances of this happening are incredibly slim. If it does occur, your dentist will simply have to perform another root canal to retreat the infection.
If you need a root canal, he will make your treatment as smooth and comfortable as possible.
