Root canal therapy is a treatment process for teeth, pulp and apical lesions. Root canal therapy is a kind of treatment method to remove the necrotic substances in root canal, properly sterilize and fill the root canal, so as to eliminate the bad stimulation of root canal contents to periapical tissues, prevent periapical lesions from occurring or promote the healing of periapical lesions.

Main disadvantages

Root canal therapy has not really improved the oral environment, which is also the root cause of dental diseases such as tooth decay. Therefore, after root canal treatment, we must pay special attention to this aspect of health care and maintain a balanced oral environment.

How to protect teeth after root canal therapy

After root canal treatment, there is generally only an empty shell around the teeth, and the teeth themselves become fragile and easy to break because of the loss of the nutrient supply of pulp, and then the teeth may bear 50 to 70 kilograms of force when chewing, and the teeth are in danger of splitting at any time during use. Therefore, doctors usually recommend braces for the teeth after root canal treatment. After root canal therapy, the center of the crown is generally empty because of the structure of the tooth itself and the need of treatment. At this time, if the braces are made directly, their breaking resistance is very poor. Generally, it is necessary to place a post at the root of the tooth and make it a solid to resist the breaking force of the teeth in use. For the posterior teeth, crowns must be made after root canal treatment, otherwise the probability of tooth fracture will be great when they bear bite force in the future. If a few posterior teeth after root canal treatment want to make a single crown, as long as the remaining dentin is repaired enough, there is no need to make a post. However, if the posterior teeth after root canal treatment are to be the pillar teeth of dentures, it is best to make posts no matter how much dentin is left. Earlier, if the tooth decayed into the pulp cavity, it was difficult for the tooth to escape the fate of tooth extraction because the root canal treatment technology was not developed at that time. At present, the technology of root canal therapy is changing with each passing day, which also greatly improves the probability of tooth retention. Therefore, it is best to put braces on the teeth after root canal treatment, so as to reduce the probability of fracture and finally achieve the purpose of preserving their teeth.
