Tooth pain after dental filling may indicate the need for a root canal treatment?

In March, I had a filling done on a molar that was close to the nerve.
After some time, I experienced several episodes of spontaneous pain that were very intense.
I consulted with a few doctors, and since tapping on the tooth and biting down did not cause pain, they advised me to monitor the situation.
I only took pain medication, and later, the spontaneous pain ceased.
Currently, my symptoms include pain for one to two minutes when consuming hot or cold food, and discomfort when biting at certain angles.
Today, I saw a doctor who tested the vitality of the tooth and found it to be responsive, but he believes my symptoms indicate irreversible pulpitis and recommended a root canal.
After I agreed, the doctor opened the tooth to alleviate my symptoms.
He noted that upon drilling, he found severe inflammation and continuous bleeding, predicting that the nerve could not be preserved.
After managing my symptoms, he scheduled the root canal for next time.

I have a few questions:
1.
Given that the tooth tests show vitality, can irreversible pulpitis still be treated with vital pulp therapy based on my current symptoms?
2.
Is it possible to wait two months for the root canal after the tooth has been opened, considering that it is currently not painful and the doctor has a longer scheduling time?
3.
The other two teeth that were filled at the same time appear normal and show no symptoms.
The doctor suggested that since they are close to the nerve, it might be wise to consider vital pulp therapy to prevent future issues like the problematic tooth.
Is this necessary?

Hello: 1.
Typically, vital pulp therapy is an out-of-pocket expense, and once the tooth is opened, treatment and medication must be administered immediately.
If the tooth has already been opened and is scheduled to be left for two months, there is unlikely to be an opportunity to perform vital pulp therapy.
2.
If you do not want to wait at all, you can ask the dentist if it is possible to switch to a completely out-of-pocket option and expedite the schedule.
If you follow the National Health Insurance billing regulations, the treatment will proceed according to the established timeline and scheduling, as root canal therapy is not a life-threatening condition and does not have an urgent time constraint.
3.
It is recommended to complete the treatment of the symptomatic tooth first before addressing other teeth; otherwise, experiencing pain in multiple teeth simultaneously can affect your quality of daily life.

More Info

Understanding post-filling tooth pain can be quite complex, especially when it involves the potential need for a root canal treatment. Based on your description, it seems you have been experiencing significant discomfort following a dental filling, particularly in a tooth that was close to the nerve. The symptoms you describe, such as spontaneous pain, sensitivity to hot and cold, and discomfort when biting at certain angles, are indicative of possible irreversible pulpitis, which is an inflammation of the dental pulp that cannot heal on its own.

1. Vitality Testing and Irreversible Pulpitis: The fact that your dentist found the tooth to have vitality (meaning the nerve is still alive) does not necessarily rule out the diagnosis of irreversible pulpitis. In cases of irreversible pulpitis, the pulp may still be alive but is inflamed to the point where it cannot recover. This condition often leads to severe pain and can result in the death of the nerve if left untreated. Therefore, while the tooth may still show vitality, the symptoms you are experiencing strongly suggest that root canal therapy is necessary to alleviate pain and prevent further complications.

2. Waiting Period for Root Canal Treatment: Regarding your question about waiting two months for the root canal treatment, it is generally not advisable to delay treatment for an extended period, especially when there is evidence of severe inflammation and bleeding. While your tooth may not be causing pain at the moment, the underlying condition can worsen, leading to more severe pain, infection, or even abscess formation. If your dentist has opened the tooth to relieve pressure and has noted significant inflammation, it is best to proceed with the root canal treatment as soon as possible to avoid complications.

3. Prophylactic Treatment for Other Teeth: As for the other two teeth that were filled at the same time but are currently asymptomatic, the decision to perform root canal treatment as a preventive measure depends on several factors. If these teeth are also close to the nerve and have a high risk of developing similar issues in the future, your dentist may recommend proactive treatment. However, if they are symptom-free and show no signs of decay or inflammation, it may be reasonable to monitor them closely rather than proceeding with unnecessary treatment. Regular check-ups and X-rays can help in assessing their condition over time.

In conclusion, it is crucial to address the symptoms you are experiencing promptly. Root canal treatment is often necessary in cases of irreversible pulpitis to save the tooth and alleviate pain. Delaying treatment can lead to more severe complications, and while preventive measures for other teeth may be considered, they should be based on clinical findings and symptoms. Always consult with your dentist about your concerns and follow their recommendations for the best outcomes in your dental health.
