It may be a mucous cyst caused by inflammation of the salivary glands within the buccal mucosa.
It is recommended to consult a dentist for further examination.

More Info


The presence of soft, pus-filled bumps on your cheek can be concerning and may indicate a few different dental or medical issues. Based on your description, it sounds like you might be dealing with an abscess, which is a localized collection of pus that can occur in various parts of the body, including the oral cavity. Here’s a detailed explanation of what might be happening and what steps you should consider taking.


Possible Causes
1. Dental Abscess: This is the most common cause of a pus-filled bump in the oral region. A dental abscess typically occurs when bacteria infect the pulp of a tooth, leading to the formation of pus. This can happen due to untreated cavities, gum disease, or trauma to the tooth. The abscess can manifest as a swollen area on the gums or cheek, often accompanied by pain, swelling, and sometimes fever.

2. Periapical Abscess: This type of abscess forms at the tip of the root of a tooth, usually due to a deep cavity or a previous dental procedure that has led to infection. It can cause significant discomfort and may require root canal treatment or extraction of the affected tooth.

3. Periodontal Abscess: This occurs in the gums and is often associated with gum disease. It can result from the buildup of plaque and tartar, leading to infection and pus formation. Symptoms may include swelling, pain, and a bad taste in the mouth.

4. Other Causes: While dental issues are the most likely culprits, other conditions such as cysts, tumors, or infections unrelated to dental health could also present as soft, pus-filled bumps. For instance, sebaceous cysts or infections of the skin can sometimes be mistaken for dental issues.


Symptoms to Look For
- Pain: Is the bump painful or tender to the touch? Pain is a significant indicator of infection.

- Swelling: Is there swelling in the surrounding area, such as the gums or cheek?
- Fever: Are you experiencing any systemic symptoms like fever or malaise?
- Discharge: Is there any drainage of pus or other fluids from the bump?

Recommended Actions
1. Consult a Dentist: Given the potential seriousness of an abscess, it is crucial to see a dentist as soon as possible. They can perform a thorough examination, possibly including X-rays, to determine the exact cause of the bump.

2. Avoid Squeezing: Do not attempt to squeeze or pop the bump, as this can worsen the infection or spread bacteria.

3. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage discomfort until you can see a dentist.

4. Maintain Oral Hygiene: Continue to practice good oral hygiene by brushing and flossing gently around the affected area to prevent further irritation.

5. Follow-Up Care: If the dentist determines that you have an abscess, they may drain it and prescribe antibiotics to help clear the infection. Follow their instructions carefully and attend any follow-up appointments.


Conclusion
Soft, pus-filled bumps on the cheek are often indicative of an underlying dental issue, particularly an abscess. Prompt evaluation by a dental professional is essential to address the infection and prevent complications. Early intervention can lead to better outcomes and relief from discomfort. Remember, your oral health is closely linked to your overall health, so do not hesitate to seek care.
