It hurts all the time during root canal treatment.

Pain during root canal therapy may have the following reasons:

1. During root canal treatment, drugs may be blocked. If the apical inflammation is particularly serious and the drainage channel is not smooth, it may cause inflammation to accumulate at the root position, thus causing severe pain. If the pain is unbearable, it is recommended to go back to the clinic in time to change the dressing and decompress.

2. Hot gutta percha is used in the filling process of root canal therapy, and the temperature is about 200℃. Some patients may feel a little uncomfortable in the process of filling teeth, including slight pain in the process of pressing the root tip.

3. Because the root of some patients is thin or extremely long, the nerve is not completely necrotic during the inactivation process of 1 week or 10 day, and active nerve tissue may remain in the root tip area. In the process of root canal treatment, because of the need to use various files, it is necessary to remove the infection, and the file may also cause pain when it touches the nerve of the residual tooth. In this case, the patient is advised to communicate with the doctor in time, and the doctor will try his best to ensure that the root canal treatment is completely painless.

The above information is for reference only. If the pain persists or worsens, it is recommended to consult a professional dentist.
