What to do if your tooth hurts when you touch it the day after a root canal?

A tooth that hurts when touched the day after a root canal may be a normal reaction; or it may have caused an infection in the apical area after the root canal was done. General treatment and medication can be taken according to the cause.
1. Normal reaction: Under normal circumstances, after root canal treatment, there will be pain in the short term, mainly due to the foreign matter in the root canal stimulating the pulp tissue, this situation generally does not require special treatment, if the pain is intolerable, you can take oral painkillers, such as ibuprofen.
2. Root canal infection: after root canal treatment, if you do not do a good job of oral cleaning care may cause apical zone infection, which leads to pain when the tooth is touched. In order to reduce the pain in the acute stage, it is necessary to open the pulp drainage as soon as possible to clean up the secretion.
If the symptoms are severe, the pulpal cavity can then be closed to minimize the irritation of the pulp.
It is recommended to observe the tooth regularly after root canal treatment. If the symptoms do not go away for a long time, or if they are more serious and you cannot chew normally, it is recommended to consult a doctor in time.
