Root canal treatment
Hello Doctor,
I have a question.
When I was a child, I broke two of my front teeth and had dental implants that have been in place for 20 years.
Recently, I noticed a small bump above the left implant, which is painful when pressed.
I went to the dentist, who said there was a pathological change inside, so they removed the implant and the screw, and recommended making a new one.
They also performed root canal treatment.
However, after a week, the bump did not go away, so the dentist performed a second root canal treatment and told me to leave medication inside for two weeks to see if it helps.
I would like to know what to do if the bump does not disappear after two weeks.
Will there be a third root canal treatment, or will surgery be necessary? If the bump does not go away, will I be unable to get an implant? I currently have a temporary tooth, and I apologize for the inconvenience.
Thank you!

As a child, I broke two of my front teeth, and later on, the dental implant on the left side developed a small bump that is painful when pressed.
This could be due to periodontal inflammation or infection around the implant, or it may indicate a recurrent infection in the root canal beneath the implant.
Therefore, the implant and the post should be removed, and root canal treatment should be redone.
However, if the bump does not disappear after several applications of medication, surgical intervention may be necessary to remove the periodontal pocket or to perform apicoectomy to completely eliminate the source of infection.
It is advisable to seek further evaluation and treatment from a dentist.

Understanding root canal treatment and its potential complications can be quite challenging, especially when symptoms persist after the procedure. From your description, it seems you are experiencing a situation that is not uncommon among patients undergoing root canal therapy, particularly when there are underlying issues that may not have been fully addressed during the initial treatment.
Firstly, it’s important to understand that a root canal treatment aims to remove infected or damaged pulp tissue from inside the tooth, followed by cleaning, shaping, and filling the root canals to prevent further infection. However, in some cases, complications can arise, such as persistent pain, swelling, or the formation of abscesses, which can manifest as the "small bump" you mentioned.
The small bump you are experiencing could be a periapical abscess, which is a localized collection of pus at the tip of the root of the tooth, often resulting from an infection. If the bump does not resolve after the second root canal treatment and the medication is placed for two weeks, it may indicate that the infection has not been fully cleared or that there is another underlying issue, such as a fracture in the tooth or a persistent infection that requires further intervention.
If the bump remains after the two-week period, your dentist may consider several options:
1. Further Root Canal Treatment: Sometimes, a third round of root canal treatment may be necessary to address any remaining infection or to clean the canals more thoroughly. This is especially true if the initial treatment did not adequately remove all infected tissue.
2. Surgical Intervention: If repeated root canal treatments do not resolve the issue, your dentist may recommend an apicoectomy, which is a surgical procedure that involves removing the tip of the tooth root along with the infected tissue. This can help to eliminate the infection and allow for healing.
3. Extraction: In cases where the tooth is severely compromised and cannot be saved, extraction may be the only option. Following extraction, options for replacement, such as dental implants, can be discussed.
Regarding your concern about whether you can proceed with dental implants if the bump does not resolve, it is crucial to ensure that any infection is fully treated before considering implants. Dental implants require a healthy environment in the jawbone to integrate properly, and any lingering infection can jeopardize the success of the implant.
In summary, if the small bump persists after the two-week medication period, it is essential to follow up with your dentist for further evaluation. They may recommend additional imaging, such as X-rays or a cone beam CT scan, to assess the situation more accurately. Open communication with your dental care provider is vital, as they can guide you through the necessary steps to address your symptoms effectively and ensure the best possible outcome for your dental health. Remember, it’s always better to address these issues sooner rather than later to prevent further complications.
