Toothache with the presence of an abscess?


Hello Doctor,
(1) I had my second molar replanted last June, but recently a pus-filled bump has appeared near my cheek.
I went to a major hospital for an examination, and the doctor there diagnosed it as a necrotic nerve.
I completed the course of antibiotics prescribed by the doctor, but the pus keeps recurring (there's also a sensation of soreness when biting down).
Even if I squeeze out the pus, it swells back up.
Should I continue to drain the pus, or should I leave it alone? Will this condition worsen? Could it lead to an infection in other areas or teeth?
(2) Additionally, the appointment for the microscopic root canal treatment is still over two months away.
Since I'm uncomfortable, the doctor just prescribes antibiotics during follow-up visits.
Is it harmful to keep taking antibiotics like this, and could it lead to antibiotic resistance?
(3) Furthermore, the gum tissue around the pus seems different from the other gums; it appears disconnected and looks like excess tissue (it seems to be hanging and can be lifted).
When I rinse with water, that piece of gum moves around, and it looks unhealthy.
Given that it's hard to clean and keeps producing pus, I want to know if the pus is caused by the tooth or if it's due to the gum tissue not healing properly.
Is it necessary to remove it and allow it to regrow? Also, the color of the pus has changed from yellowish to bloody; does this indicate a worsening condition?
(4) Currently, I feel sensitivity in some of my interproximal spaces when using dental floss, but after an examination and X-rays, the doctor confirmed there are no cavities.
What could be causing this? Would applying fluoride be beneficial?

Hello MOLO:
1.
The presence of a pus-filled blister around the second molar indicates that the periodontal tissue is still in an inflammatory state, or that the replanted tooth's pulp has not yet undergone root canal treatment.
If the blister persists, it is recommended to return for further examination by a dentist.

2.
Sensitivity when using dental floss between teeth suggests that there is inflammation in the gums or plaque buildup in the interdental spaces.
Once cleaned properly, the sensitivity should naturally improve.

More Info


Tooth pain and the presence of an abscess can be concerning and often indicate underlying dental issues that require prompt attention. Based on your description, it seems that you are experiencing a complex situation involving a second molar that has undergone treatment, but is now presenting with recurrent abscesses and discomfort. Let’s break down your concerns and provide some insights into the potential causes, treatment options, and management strategies.


(1) Understanding the Abscess and Pain
The presence of a pus-filled bump (abscess) near your second molar suggests that there is an ongoing infection, likely due to necrotic (dead) nerve tissue or bacteria that have infiltrated the surrounding tissues. When a tooth's nerve dies, it can lead to the formation of an abscess, which is the body’s way of fighting off infection. The fact that you are experiencing recurrent swelling and pain indicates that the infection is not resolving on its own.

Should you squeeze the abscess? It is generally not advisable to squeeze or drain an abscess on your own, as this can lead to further complications, including the spread of infection. Instead, it is crucial to follow up with your dentist or an endodontist (root canal specialist) for appropriate treatment.

(2) Antibiotic Use and Resistance
You mentioned that you have been prescribed antibiotics to manage the infection. While antibiotics can help control bacterial growth, they do not address the root cause of the infection, which is the necrotic tooth. Prolonged use of antibiotics can lead to antibiotic resistance, making future infections harder to treat. It is essential to use antibiotics judiciously and under the guidance of a healthcare professional.


(3) The Condition of the Gum Tissue
The gum tissue around the abscess appears abnormal, which could indicate periodontal issues or a reaction to the infection. The "extra" tissue you describe may be a result of inflammation or a condition known as a gingival hyperplasia, which can occur due to chronic irritation or infection. If the tissue is necrotic or not healing properly, surgical intervention may be necessary to remove the affected tissue and promote healing.

The change in color of the pus from yellow to bloody suggests that the infection may be worsening, and this should be evaluated by a dental professional as soon as possible.


(4) Tooth Sensitivity and Other Symptoms
You noted sensitivity in some of your teeth, even after being told there are no cavities. This sensitivity could be due to several factors, including:
- Gum Recession: Exposed tooth roots can lead to sensitivity.

- Dentin Sensitivity: If the enamel is worn down, the underlying dentin can become exposed, leading to pain.

- Referred Pain: Sometimes, pain from one tooth can be felt in another due to nerve pathways.

Fluoride treatments can help strengthen enamel and reduce sensitivity, but they will not address the underlying infection or abscess.


Recommendations
1. Seek Immediate Dental Care: Given the complexity of your symptoms, it is crucial to see a dentist or an endodontist as soon as possible. They may recommend a root canal treatment to remove the infected tissue and prevent further complications.

2. Avoid Self-Treatment: Do not attempt to drain the abscess yourself. This could lead to more severe infections or complications.

3. Monitor Symptoms: Keep track of any changes in your symptoms, including the size of the abscess, pain levels, and any new symptoms that arise.

4. Discuss Antibiotic Use: Talk to your dentist about the duration of antibiotic treatment and any concerns regarding resistance.

5. Consider Gum Health: If the gum tissue remains problematic, your dentist may refer you to a periodontist for further evaluation and treatment.

In summary, your situation requires careful evaluation and treatment by a dental professional. Prompt action can help prevent further complications and alleviate your discomfort.
