Only a dentist can determine whether a root canal procedure is required for a tooth. The dentist will examine the infected tooth to make an overall assessment about the extent of decay and decide on the best course of treatment. Sometimes a root canal treatment is required even when there are no overt symptoms.
However, two most common symptoms that indicate that root canal is a necessity are as follows:
- Chronic pain in the tooth.
- Tenderness or swelling in the gum next to the problem tooth.
Other conditions that indicate necessity for a root canal are as follows:
- A problem identified only by an X-ray. Nerve tissue within the tooth could decay and become necrotic without pain or any other symptoms. This situation arises when the body’s natural defense mechanism is able to limit the rate of decay while not totally being able to overcome it. The extent of decay becomes evident only through an x-ray which will indicate the need of a root canal procedure.
- A relentless and chronic pimple on the gum. This is the result of a tooth with a dead nerve. The pimple is a drain, called a fistulous tract, which comes and goes and discharges pus. Quite often such a condition shows up during a routine examination.
- An exposed nerve that leads to degeneration of nerve tissue. This condition could lead to a painful abscess and further complications of the tooth. The dentist might decide an opportune root canal is the best option.
- Teeth traumatized in an accident. The nerve tissue could have been damaged indicating the need of root canal treatment.
