A small bump or pimple-like spot on your gums may seem harmless, especially if it does not cause significant pain. However, a recurring bump that drains pus can be a sign of an underlying dental infection. One possible cause is a dental fistula, which can develop when infection creates a pathway for pus to drain through the gum.
If you notice a persistent gum boil, unusual drainage, swelling, bad taste, or sensitivity around a tooth, it is important to have the area evaluated by a dental professional. Understanding the causes, symptoms, and treatment options can help you recognize the problem and seek appropriate care.
What Is a Dental Fistula?
A dental fistula is an abnormal pathway that allows infection or pus from an infected tooth or surrounding tissues to drain toward the surface of the gums. It may appear as a small pimple-like bump, sometimes called a gum boil.
A fistula often develops because of an infection beneath or around a tooth. Although the bump may drain and temporarily reduce pressure, drainage does not necessarily mean the infection has been eliminated. The underlying source still needs professional evaluation and treatment.
What Causes a Dental Fistula?
Several dental problems can contribute to the development of a fistula. Common causes include:
- An untreated tooth infection
- Advanced tooth decay
- A cracked, broken, or injured tooth
- An infection around the tooth root
- Gum or periodontal disease
- Dental trauma
- An infection associated with a previous dental procedure
When bacteria enter the tooth or surrounding tissues, an infection can develop and lead to an accumulation of pus. Without appropriate treatment, the infection may create a drainage pathway through the gum.
What Are the Symptoms of a Dental Fistula?
The appearance of a small bump on the gums is one of the most noticeable signs. However, symptoms can vary depending on the location and severity of the infection.
Common dental fistula symptoms may include:
- A pimple-like bump on the gums
- White or yellow fluid coming from the bump
- Pus drainage
- A bad taste in the mouth
- Persistent bad breath
- Redness or swelling around the affected area
- Tooth sensitivity to hot or cold foods
- Discomfort when biting or chewing
- Tenderness around a tooth
- Recurring swelling near the same tooth
A dental fistula does not always cause severe pain. In some cases, drainage can relieve pressure and make the problem seem less serious. However, a lack of pain does not necessarily mean the infection has disappeared.
Is a Gum Boil the Same as a Dental Fistula?
The terms “gum boil” and “dental fistula” are often used when describing a pimple-like bump on the gums. A gum boil may be associated with an abscess or an infection that has created a drainage pathway.
Because several conditions can cause bumps or swelling on the gums, it is important not to diagnose the problem based only on its appearance. A dentist in Marietta can examine the area and determine whether an infected tooth, gum disease, or another dental problem is responsible.
Can a Dental Fistula Go Away on Its Own?
A dental fistula may temporarily shrink or stop draining, but this does not necessarily mean the underlying infection has been cured.
Dental infections generally require professional evaluation and treatment. The appropriate treatment depends on what is causing the infection and whether the tooth can be preserved. Ignoring recurring drainage can allow the underlying dental problem to continue or worsen.
If you repeatedly notice a gum boil or pus around a tooth, schedule a dental evaluation rather than waiting for the bump to disappear.
How Is a Dental Fistula Treated?
The goal of dental fistula treatment is to address the underlying source of infection. Your dentist will examine your teeth and gums and may use dental X-rays or other diagnostic methods to identify the affected tooth.
Treatment may include:
Root Canal Treatment
When an infected or damaged tooth is responsible for the infection, root canal treatment may help save the natural tooth. During the procedure, the infected tissue inside the tooth is removed, the root canals are cleaned, and the tooth is sealed.
Treating the source of infection can allow the surrounding tissues and gum fistula to heal.
Dental Abscess Drainage
Depending on the condition, a dentist may need to drain an abscess to remove accumulated pus and reduce pressure. Drainage is generally performed as part of a broader treatment plan that addresses the source of infection.
Periodontal Treatment
If gum disease is contributing to the infection, periodontal treatment may be recommended. Professional cleaning and other periodontal procedures can help remove bacteria, plaque, and tartar from areas that are difficult to clean at home.
Tooth Extraction
When a tooth is severely damaged or cannot be successfully restored, extraction may be recommended. Removing the source of infection can help prevent the problem from continuing.
Antibiotics
Antibiotics may be recommended in certain situations, particularly when there are signs that a dental infection is spreading or causing systemic symptoms. However, antibiotics alone do not usually eliminate the underlying dental problem. The source of the infection still needs appropriate dental treatment.
When Should You See a Dentist?
A recurring gum bump, pus drainage, swelling, or signs of infection should not be ignored. Schedule a dental appointment if you notice symptoms that persist or repeatedly return.
Seek urgent dental care if you experience significant swelling, worsening pain, fever, difficulty swallowing, or other signs of a spreading infection. Severe swelling that interferes with breathing or swallowing requires immediate emergency medical attention.
How Can You Help Prevent Dental Infections?
Good oral hygiene and regular dental visits can reduce the risk of tooth decay, gum disease, and other problems that may contribute to dental infections.
Helpful habits include:
- Brush your teeth twice a day with fluoride toothpaste.
- Clean between your teeth every day.
- Limit frequent sugary foods and drinks.
- Replace your toothbrush regularly.
- Protect your teeth during sports or activities where dental injuries are possible.
- Schedule routine dental examinations and cleanings.
- Have tooth pain, cracks, or dental injuries evaluated promptly.

Frequently Asked Questions (FAQ’s)
Is a dental fistula painful?
Not always. Some dental fistulas cause little or no pain because the drainage pathway can release pressure. However, the infection responsible for the fistula may still require treatment.
What does a dental fistula look like?
It may look like a small pimple, blister, or raised bump on the gums. The area may be red or swollen and can sometimes release white or yellow fluid.
Can a gum boil be caused by an infected tooth?
Yes. An infection associated with a tooth can lead to an abscess and create a drainage pathway toward the gums, resulting in a gum boil or fistula.
Will antibiotics cure a dental fistula?
Antibiotics can help control certain dental infections, particularly when the infection has spread or caused systemic symptoms. However, they may not remove the underlying source of the infection. Dental treatment may still be necessary.
What happens if a dental fistula is left untreated?
The underlying infection may persist and potentially spread to surrounding tissues. Even when a gum bump temporarily disappears, the source of the infection may remain.
