Periapical gingival abscess?


Hello Dr.
Chiu, I have some questions.
I have a tooth with a gum boil at the apex of the root that sometimes recedes and sometimes appears.
That tooth has broken in half for an unknown reason.
I also have another tooth that has a fracture straight through the middle.
I'm not sure if the fractures have affected the roots, but I don't feel any pain.

Chen, 20~29 year old female. Ask Date: 2023/07/11

Dr. Qiu Qiongyao reply Dentistry


Hello Ms.
Chen: Please visit the dental clinic for an examination, as X-rays are needed for assessment.

Hello! Thank you for reaching out with your concerns about dental abscesses and the condition of your teeth. It sounds like you're experiencing some complex dental issues, and I’ll do my best to provide you with a comprehensive understanding of dental abscesses, their causes, and potential treatments.

A dental abscess is a localized collection of pus that can occur in different parts of the tooth, often due to an infection. The most common type is a periapical abscess, which occurs at the tip of the tooth root. This condition typically arises when bacteria invade the dental pulp, often due to untreated cavities, trauma, or previous dental procedures that may have compromised the tooth's integrity.

In your case, the presence of a pus-filled bump on your gums (the abscess) indicates that there is an ongoing infection. The fact that it sometimes recedes and then reappears suggests that the infection may not be fully resolved, and it could be linked to the condition of your teeth, especially since you mentioned that one of your teeth has broken and the other has a significant fracture.

The broken tooth can lead to exposure of the dental pulp, allowing bacteria to enter and cause infection. Even if you are not experiencing pain, it is crucial to address these issues promptly, as infections can spread and lead to more severe complications, including systemic infections.


Causes of Dental Abscesses:
1. Untreated Cavities: Bacteria can penetrate through cavities into the pulp, leading to infection.

2. Trauma: Physical damage to a tooth can expose the pulp or fracture the tooth, allowing bacteria to enter.

3. Previous Dental Work: If a tooth has undergone root canal treatment and the procedure was not successful, it can lead to reinfection.

4. Gum Disease: Periodontal disease can also contribute to the formation of abscesses.


Treatment Options:
1. Antibiotics: If you have an active infection, your dentist may prescribe antibiotics to help control the infection.

2. Drainage: The abscess may need to be drained to remove the pus and alleviate pressure. This is often done by making a small incision in the gum.

3. Root Canal Treatment: If the tooth is salvageable, a root canal may be performed to remove the infected pulp and seal the tooth.

4. Extraction: If the tooth is severely damaged and cannot be saved, extraction may be necessary. Following extraction, options for replacement, such as implants or bridges, can be discussed.

5. Follow-up Care: After treatment, it’s essential to maintain good oral hygiene and follow up with your dentist to monitor the healing process.

Given your situation, it is crucial to consult with a dental professional who can assess the condition of your teeth and the abscess. They may take X-rays to determine the extent of the damage and the best course of action. Ignoring these symptoms can lead to more significant health issues, so I encourage you to seek treatment as soon as possible.

In summary, dental abscesses are serious conditions that require prompt attention. Understanding the underlying causes and seeking appropriate treatment can help prevent further complications and preserve your dental health. Please take care of your dental needs, and I wish you a swift recovery!
