Overview Of Root Canal

A root canal is a dental treatment performed to deep clean the infections inside the inner chambers of a tooth. By cleaning the infections in the initial stages, this treatment avoids the situation of tooth removal. A root canal will be concluded when your tooth pulp is affected by the bacterial actions causing pain and discomfort.

The Causes Of Pain After A Root Canal

This problem which may spread to other teeth can be identified by pain while chewing, eating, and drinking hot or cold drinks. Although these symptoms may reduce with time even without treatment, they can lead to more complications with time.

A dentist or oral expert performs a root canal treatment. You will be given a local anesthetist before starting the treatment. Later, the dentist will place a thin piece of rubber on your affected tooth and nearby gums and drill a hole in your tooth’s crown.

Understanding Pain After A Root Canal

Experiencing pain after a root canal treatment is quite normal. Even after a safe and successful treatment people experience pain.

Reason For Pain After A Root Canal

Some of the most common reasons that lead to pain after a root canal treatment are:

  • Inflammation in the tissue

The tissues around the gums may remain swollen even after the treatment. It occurs mainly because of the small nerves in the ligaments and tissue. Although the infected nerve is removed from the tooth root, these remaining small nerves lead to swelling causing pain and discomfort.

  • Instrument damage

The damage caused to the surrounding tissue by the instruments used in the root canal treatment may lead to persisting pain and swelling.

  • Temporary filling

If the temporary dental filling in the tooth is not leveled properly, it will stay elevated than the surrounding area. As a result, the chances of biting that spot while eating are higher. This can cause intense pain.

How Long Does It Take To Recover After A Root Canal?

However, this recovery period may vary according to the patient’s health condition. Some people might take over a week to relieve the pain and discomfort. But, if the problems persist consult your healthcare provider to avoid further complications.

  • Fluid discharge from the treated tooth
  • Persistent tooth sensitivity
  • Dark and discolored tooth
  • The infection spreads to other body parts causing various issues like sinus infection

  • Eat soft well-cooked foods like mashed potatoes, cottage cheese, yogurt, and smoothies.
  • Avoid chewing with your treated teeth.

As mentioned before, root canal pain will decrease over time. However, some people may experience swelling and pain even after a week of the treatment.

In some cases, people do not gain any improvements in their condition even after using painkillers and over-the-counter medicine. All these symptoms denote the possibility of infections or other problems.
