Why are root canals painful after treatment?
Tooth pain after root canal treatment plagues many patients. Because of the treatment, the dentist does not clean the pulp thoroughly. This residual pulp continues to infect bacteria inside the tooth and the tooth forms an inflammation in the tissue around the root tip. The pus concentrates at the root of the tooth, so the tooth becomes locally swollen and painful. After an attack of acute periapicalitis, if not treated promptly and effectively, it can turn into chronic periapicalitis, where the tooth suffers from chronic periapicalitis and a fistula develops next to the tooth and abscesses for a long period of time.
Causes of tooth pain after root canal treatment
Before performing a root canal, the dentist fails to treat a portion of the oral disease and the inflammation of the tooth is not effectively eradicated. During the root canal procedure, the dentist was inexperienced and performed the procedure improperly, resulting in the bacteria in the tooth not being completely cleaned out. After the root canal treatment, instead, the bacteria spread everywhere and then the tooth developed severe pain.
Poor technique by the dentist can lead to failure of the root canal treatment. After the end of the root canal treatment, if the length of the root canal that fills the tooth is not the right distance from the gums, the root canal will constantly rub against the soft tissues of the tooth, which can lead to some inflammation of the tooth. If this friction is dealt with in time, the tooth can become infected with more bacteria, leading to a complete failure of the root canal treatment.
There is a growing variety of root canal filling materials available in dentistry today. Each material produces different results. Before proceeding with a root canal, the dentist should conduct a thorough examination of the patient to keep abreast of some physical characteristics, including allergic reactions. Once the examination is complete, the doctor can avoid materials that are detrimental to the patient when choosing a root canal filling material. Also, careful selection of filling materials by the dentist will not only improve the success of the root canal treatment, but also reduce the patient’s pain during the procedure.
Is it always a failure to have pain in the tooth after a root canal?
Even if the root canal treatment is successful, the tooth may still feel slightly painful. This is because the tooth will feel uncomfortable to the patient after the root canal treatment because the filling is just inside the tooth. Some patients with sensitive gums may experience swelling and discomfort, and may even experience mild pain, but if the painful sensation in the tooth goes away in about a week, the patient should ignore it.
How to deal with tooth pain after root canal
First an x-ray of the tooth will be taken and the doctor will evaluate the tooth for root cracks. If the patient’s tooth does not have root cracks, root canal retreatment can be performed. It is important for the patient to find a more experienced dentist in order to increase the success of the root canal retreatment.
If the patient’s tooth does not have a significant tendency to heal after root canal re-treatment, the dentist may consider performing an apical surgery to remove the diseased tissue and fill the apical portion of the tooth after the root is removed to control the infection in the root canal. The alveolar canal will slowly return to normal and the tooth will only be able to resume normal chewing function. If the tooth pain is due to inadequate pulp cleaning, the tooth has residual pulpitis. The dentist will re-clean the remaining pulp and fill the material again.
