That Little Bump on Your Gum Might Be Telling You Something
Have you ever noticed a small pimple-like bump on your gum and dismissed it as nothing serious? That little bump could be a dental fistula—and ignoring it may lead to consequences far worse than discomfort. At Lexington Dental of Owasso, our DDS Dr. Jacob Cary wants patients in Owasso to understand the warning signs their mouth is sending them.

What Is a Dental Fistula?
A dental fistula (also called a sinus tract or gum boil) is a small channel that forms in the gum tissue to drain pus from an infection deep inside the tooth or jawbone. Think of it as your body’s attempt to relieve pressure from a bacterial infection it cannot fight on its own.
It typically appears as a raised, white, yellow, or red bump on the gums—sometimes with a small opening at the tip. You may notice a salty or bitter taste in your mouth, which is the fistula actively draining.
What Causes a Dental Fistula?
Dental fistulas are always a sign of an underlying infection. Common causes include:
- A tooth abscess (bacterial infection at the root tip or in the pulp)
- Advanced gum disease (periodontitis) that has spread to the bone
- A failed or failing root canal that didn’t fully eliminate the infection
- A cracked or fractured tooth that allowed bacteria to enter
- Trauma to the tooth that went untreated
Dental Fistula Symptoms to Watch For
Not everyone with a dental fistula experiences pain, which is exactly why they’re so often ignored. Because the fistula is actively draining the infection, pressure is relieved, and pain may be minimal. Don’t let the absence of pain fool you. Warning signs include:
- A small bump or blister on the gum near a tooth
- Persistent bad breath or a foul taste in your mouth
- Mild to moderate tooth or gum sensitivity
- Swelling in the gums or face
- The bump appears to “pop” and drain, then return
Why You Shouldn’t Ignore a Dental Fistula
A dental fistula never resolves on its own. While it may appear to come and go, the underlying infection remains active the entire time. Left untreated, the consequences can be serious:
- Bone Loss: The infection slowly destroys the jawbone surrounding the affected tooth.
- Tooth Loss: Severe enough infection or bone destruction can make the tooth unsalvageable.
- Spread of Infection: Oral bacteria can enter the bloodstream and travel to the heart, lungs, or brain—a rare but life-threatening risk.
- Damage to Neighboring Teeth: The infection can spread to adjacent teeth and tissue.
How Is a Dental Fistula Diagnosed?
Dr. Jacob Cary will examine the bump visually and probe the area gently to assess its depth. A dental X-ray is typically taken to trace the fistula back to its source and evaluate the extent of infection or bone involvement. In some cases, a small piece of gutta-percha (a rubber-like material) is threaded into the tract to confirm its origin on the X-ray.
Treatment Options for Dental Fistula
The right treatment depends on the severity of the infection and the condition of the affected tooth. Options include:
Root Canal Treatment
Root canal therapy is the most common treatment. If the tooth is salvageable, Dr. Jacob Cary will remove the infected pulp, clean and seal the root canals, and place a crown. Once the source of infection is eliminated, the fistula typically heals on its own within a few weeks.
Antibiotics
Antibiotics alone cannot cure a dental fistula because they cannot penetrate the dead tissue inside an infected tooth. They may be prescribed in conjunction with dental treatment to help control the spread of infection.
Tooth Extraction
If the tooth is too damaged to save, extraction removes the source of infection entirely. Replacement options such as dental implants or bridges can be discussed with Dr. Jacob Cary at Lexington Dental of Owasso.
Gum or Bone Surgery
In advanced cases where the infection has spread to the bone or surrounding tissue, surgical debridement or bone grafting may be necessary to restore health and structure.
Can a Dental Fistula Be Prevented?
In most cases, yes. Dental fistulas are the result of infections that develop over time—often from cavities, gum disease, or trauma that goes untreated. Prevention strategies include:
- Brushing twice daily and flossing every day
- Scheduling regular cleanings and checkups at Lexington Dental of Owasso
- Treating cavities and gum disease early, before they progress
- Wearing a mouthguard during contact sports to prevent tooth trauma
- Never ignore a toothache, sensitivity, or unusual bump in your mouth
