Root canal treatment is generally necessary for teeth with exposed nerves, unless the pulp is accidentally exposed in young permanent teeth.
1. The nerve sensitivity of the exposed nerve will be high, and there will be obvious pain, which is intolerable and may recur at night. If not treated in time, it may induce chronic pulpitis, which may also lead to apical periapical inflammation and other diseases in the later stage, therefore, root canal treatment is needed in time, which can relieve the pain, and at the same time, prevent other complications.
2. Root canal treatment is needed to remove the nerve of the tooth after the nerve is exposed, and root canal filling and crown restoration are also needed to maintain the stability of the tooth.
3. When the pulp of a young permanent tooth is exposed accidentally, for example, when the crown is fractured and the pulp cavity is exposed due to trauma, in order to promote the development of the root of the tooth, pulpotomy and pulp capping can be used to preserve the living pulp.
Usually it is best not to eat too hard food often, but also need to keep the mouth clean, to avoid infection, the emergence of exposed nerve timely to the hospital for treatment.
