Is Bleeding Normal After Dental Nerve Treatment with Medication? - Dentistry

Dental nerve treatment with medication is causing continuous bleeding?


The tooth has a piece cracked off, and after evaluation by the dentist, it was determined that a root canal treatment is necessary, followed by a crown placement.
The method for the root canal involves using medication to kill the nerve.
Today was the third follow-up appointment for medication placement.
When the dentist removed the old medication, I gradually began to feel pain, and afterward, it was quite painful.
When I spat, I noticed that the tooth was bleeding.
I immediately took pain medication, and the pain gradually subsided, with no further bleeding.
Is it normal to experience bleeding during the root canal treatment with medication? Could it be possible that the dentist accidentally injured the gum while removing the old medication?

Hello, sir: It is recommended that you visit the outpatient clinic for an evaluation in order to obtain a proper diagnosis, as we cannot determine if the symptoms you described are indeed caused by nerve involvement.
Generally, the occurrence of blood in saliva is often due to excessive dental calculus leading to gum inflammation.
Therefore, please return for another examination to confirm the cause.

More Info


Bleeding after dental nerve treatment, particularly during the process of root canal therapy where medication is used to kill the nerve, can be concerning for patients. However, it is important to understand the context and the potential reasons behind this occurrence.

In your case, it seems that you underwent a procedure where the dentist used medication to treat the nerve of a tooth that had been damaged, likely due to a crack. During the treatment, the dentist removed the old medication, which can sometimes cause discomfort or pain, especially if the surrounding tissues are sensitive or inflamed. The presence of bleeding after such a procedure can occur, but it is not typically considered a standard or expected outcome.

Bleeding can happen for several reasons:
1. Tissue Trauma: When the dentist removes the old medication, there is a possibility of inadvertently causing minor trauma to the surrounding gum tissue. This can lead to localized bleeding, especially if the area is already inflamed or sensitive due to the underlying dental issue.

2. Inflammation: If there is pre-existing inflammation in the gums or surrounding tissues, the act of manipulating these areas during treatment can exacerbate the condition, leading to bleeding.

3. Medication Reaction: Sometimes, the medications used in root canal treatments can irritate the surrounding tissues, which may also contribute to bleeding.

4. Underlying Conditions: If there are any underlying conditions affecting your blood clotting or gum health, this could also play a role in bleeding during or after dental procedures.

In your situation, since you mentioned that the bleeding stopped after taking pain medication and did not continue, it suggests that the bleeding was likely minor and self-limiting. However, it is always advisable to follow up with your dentist if you experience any unusual symptoms, such as prolonged bleeding, significant pain, or swelling, as these could indicate a more serious issue.

Regarding your concern about whether the dentist may have accidentally injured the gum tissue while removing the old medication, it is indeed possible. Dental procedures can sometimes lead to minor injuries to the soft tissues, especially in areas that are already compromised. If the bleeding was minimal and resolved quickly, it may not be a cause for concern, but it is essential to communicate any worries with your dental care provider.

In summary, while some bleeding can occur during or after nerve treatment, it is not the norm and should be monitored. If you have any ongoing concerns or if the bleeding recurs, it is crucial to consult your dentist for a thorough examination and appropriate management. Regular follow-ups and open communication with your dental care team are key to ensuring your oral health and addressing any complications that may arise during treatment.
