Root canal treatment


Dear Doctor, I had my root canal treatment completed today, and during the final sealing, when the doctor inserted the gutta-percha with the needle, I suddenly felt a sharp pain as if I was poked in the nerve.
I asked the doctor about it, and he said it was nothing to worry about.
Later, he heated the gutta-percha for sealing.
I'm a bit concerned whether the root canal was cleaned properly, so I'm reaching out for your advice.
Thank you, Doctor.

Hello, it is normal to experience swelling and tenderness during the first month after root canal filling.
It is recommended to monitor the situation for up to six months.
If the symptoms do not improve after six months, a retreatment may be necessary.
Additionally, it is advisable to continue taking X-rays to closely observe the degree of improvement in chronic inflammation.

More Info


Root canal treatment (RCT) is a common dental procedure designed to treat infection or damage within the pulp of a tooth. It involves removing the infected or damaged pulp, cleaning and disinfecting the root canals, and then filling them to prevent further infection. However, many patients experience pain and discomfort during and after the procedure, which can lead to concerns about the effectiveness of the treatment.

From your description, it seems that you experienced a sharp pain when the dentist inserted the gutta-percha (the material used to fill the canals) into the root canal. This sensation can occur if the instrument comes into contact with the nerve endings in the tooth or surrounding tissues. While it is not uncommon to feel some discomfort during the procedure, it is essential to communicate any pain to your dentist immediately, as they can adjust their technique or provide additional anesthesia if necessary.

The concern about whether the root canal was adequately cleaned is valid. Incomplete cleaning can lead to persistent pain and infection. However, it is important to note that some discomfort after the procedure can be expected as the tissues heal. The pain you felt during the filling process does not necessarily indicate that the root canal was not cleaned properly. It may simply be a reaction to the procedure itself.

If you continue to experience significant pain after the treatment, it is crucial to follow up with your dentist. They may recommend taking X-rays to assess the condition of the tooth and the effectiveness of the root canal treatment. In some cases, if there is evidence of residual infection or if the pain persists, further treatment may be necessary, which could include retreatment of the root canal or even surgical intervention.

In addition to the physical aspects of root canal treatment, it is also essential to consider the psychological impact. Many patients experience anxiety about dental procedures, which can exacerbate their perception of pain. Techniques such as deep breathing, mindfulness, and relaxation exercises can help manage anxiety during dental visits.

Post-treatment care is also vital. Your dentist may prescribe pain relievers or recommend over-the-counter medications to help manage discomfort. It is essential to follow their instructions regarding medication and to maintain good oral hygiene to promote healing.

In summary, while experiencing pain during root canal treatment can be concerning, it does not automatically indicate that the procedure was unsuccessful. Communication with your dentist is key to addressing any concerns and ensuring that you receive the appropriate care. If pain persists or worsens, do not hesitate to seek further evaluation to rule out any complications. Remember, the goal of root canal treatment is to save the tooth and restore its function, and with proper care, most patients can achieve a successful outcome.
