|Root Canal Treatment Complications|
|Sometimes when a root canal is opened for treatment, the oxygen in the air will prompt some bacteria to start growing, in such a way causing inflammation and pain.|
Bacteria may get pushed out through the tips of the roots. Blood vessels go into the tooth through a small hole (the apex of the root) at the bottom of the root. Sometimes it happens that during a root canal procedure, bacteria are pushed out through this small hole into surrounding tissue. In this case, the surrounding tissue will become inflamed and possibly infected. Your doctor will probably prescribe painkillers, and sometimes antibiotics, but the site could be painful until it clears up.
A root canal treatment can pierce the side of the tooth. This can occur if the canal is bowed or if the canal cannot be positioned. Medical instruments are flexible so that they bend as the canal curves, but sometimes the instrument makes a small hole in the side of the tooth. In case if saliva get into the hole, the tooth will have to be treated further or even extracted. If the hole is far enough under the gum line that saliva can't reach it, it may cure.
A root canal may be missed or an entire canal may not be completely cleaned out. Locating canals within the tooth can be troublesome. If a canal or an offshoot of a canal isn't located and cleaned out, the tooth can stay infected and the root canal procedure will have to be repeated. This also can occur if a canal isn't measured properly and pieces of infected or inflamed pulp are left near the bottom. Sometimes root canals have branches that are not accessible to traditional treatment.
A file may fracture. The tip of a file may crack off inside the tooth. As a rule, it's possible to leave the piece in the tooth and finish the root canal. But if the cleaning of the canal has not been completed, the file piece may have to be removed. Sometimes this can be done from the top of the tooth. Though, in some cases, the file can only be removed through a surgical procedure called an apicoectomy. A small incision is made in the gum to reach the root of the tooth, and the portion of the root containing the file piece is removed.
