Why do I have severe pain after a root canal?
Under normal circumstances, the pain caused by the procedure will gradually go away after the root canal treatment. If there is constant pain in the tooth, you can tell that the root canal has failed. Root canal treatment of a tooth requires high skill and equipment, is tedious, and every detail of the treatment process can easily lead to root canal failure. There are several main reasons why pain occurs after root canal treatment:
The pulp is not clean.
Root canals are incompletely cleaned during root canal therapy, and viable pulp remains in the root canal, producing pain in the tooth due to a combination of wounding, drug irritation, and inflammation.
root canal omission
The root canal system is very complex, and root canals in certain positions are often mutated. The dentist does not find all of the root canals during root canal treatment, resulting in some root canals still remaining with pulp. These root canals become the best place for bacteria to multiply. The tooth develops residual pulpitis or periapical inflammation.
Root canal disinfection is ineffective
Bacterial infection is the main cause of endodontic and periapical infections. Under the root canal disinfection procedure, if the dentist does not follow the procedure to the letter, the tooth will not be disinfected properly and more bacteria will remain in the root canal and too much of it will make the root canal treatment fail.
Certain patients choose to fill fillings after root canal treatment instead of getting braces in place. The tooth splits after biting into a hard food object and the tooth may feel painful. At this point the tooth may no longer be retained. Therefore, getting braces on a tooth after a root canal can greatly reduce the risk of a split tooth.
root canal excessive length
The substance that the dentist fills into the root canal is limited in length. The dentist will go and measure the optimal length of the root canal filling during the root canal procedure. If the dentist doesn’t find the right length because of poor technique. The length of the root canal filling will be too long and the root canal filling will constantly rub against the gums, eventually leading to inflammation of the tooth. The patient will also feel pain.
