What are Dental Fistulas?
What are Dental Fistulas?
A dental fistula is a tube-like channel, often called a fistula tract, that forms in response to an infection. It connects an infected area, usually at the tooth root or in the gums, to the outer surface of the mouth tissue, allowing pus from a deeper area to drain. Unlike other oral problems such as canker sores or abscesses, which also represent painful lesions, the dental fistula is specifically characterized by its tract or channel nature. Various forms occur, including the most common root fistula, which arises from inflammation at the root tip of a tooth. Typically, it is a longer-term, thus chronic process, during which the inflammation seeks its way to the "surface." Since chronic processes here often proceed with little to no pain, this development can go almost unnoticed.

Causes and Risk Factors
Causes and Risk Factors
Dental fistulas usually result from a bacterial infection that settles deep in the tooth root or surrounding tissue. Risk factors can vary:
Dental fistulas usually result from a bacterial infection that settles deep in the tooth root or surrounding tissue. Risk factors can vary:
Root canal infections: These often result from untreated cavities, allowing bacteria to penetrate deeper into the tooth and thus to the root and its tip in the bone.

Poor oral hygiene: Insufficient tooth brushing and neglect of interdental care can lead to an accumulation of bacteria and thus to cavities, which can then lead to a fistula due to an infection of the tooth root.

Weakened immune system: Individuals with a weaker immune system, due to chronic diseases or immunosuppressive therapy, are more susceptible to tooth infections and thus to the development of fistulas.

Gum inflammation and periodontitis: Chronic inflammations of the gums and the tooth bed can increase the risk for dental fistulas. Even a very deep gum pocket can form a fistula tract, although the inflammation has the opportunity to drain upwards to the gum. The inflammation in deep gum pockets is usually caused by anaerobic bacteria, to whose presence and metabolic end products the body reacts with the dissolution of surrounding tissue and pus formation.

Traumas and injuries in the oral cavity: Injuries or traumas in the mouth area can pave the way for infections that develop into fistulas.

Symptoms and Diagnosis
Symptoms and Diagnosis
Dental fistulas can initially be symptom-free, which complicates early detection. Typical symptoms of dental fistulas include:

Swelling and sensitivity of the gums: Often around the affected tooth.

General symptoms: Bad taste in the mouth and sometimes slight fever.
Diagnosis begins with a thorough examination of the oral cavity by a dentist. This is followed by an X-ray to assess the spread of the infection. Through these examinations, the dentist can determine if a fistula is present in the tooth and recommend a suitable treatment method. In some cases, further imaging diagnostics may be required to determine the exact location and size of the fistula’s origin.

Treatment Options for Dental Fistulas
Treatment Options for Dental Fistulas
Although it may be tempting, one should not attempt to squeeze a dental fistula oneself, as this can lead to the spread of inflammation and further health problems. If you notice a dental fistula or the symptoms mentioned above, you should immediately seek a dental practice. There you will be informed about the possibilities of dental fistula treatment.

Root canal infections are the main cause of the development of dental fistulas. By treating the cause, usually through conservative, non-surgical root canal treatment, the fistula tract typically heals without problems. Treating the underlying dental infection is crucial to prevent or treat fistula formation. If it is a fistula of the periodontium, i.e., a periodontal fistula, periodontitis treatment is urgently indicated.

Conservative Treatment Approaches
Conservative Treatment Approaches
Non-surgical, classical root canal treatment with cleaning, preparation, and disinfection of the inflamed tooth/root canal.

Periodontitis and pocket treatment in case of involvement of the periodontal apparatus.

Antibiotic therapy: A possible first step to combat the infection and prevent the spread of bacteria if immediate classic root canal treatment is not possible due to too strong signs of inflammation. This can be systemic through the ingestion of tablets, and in individual cases, a local application in the form of ointments or inserts can also occur.

Pain management: Use of pain relievers to alleviate acute discomfort.

Apicoectomy: Performed when the infection is localized at the root tip of the tooth and cannot be managed or is not manageable by a “normal” root canal treatment. This may sometimes be necessary long after a root canal treatment has been performed.

The connection between oral hygiene or oral health and the development of dental fistulas is an important topic in dentistry. Poor oral hygiene and certain oral diseases, such as tooth decay and periodontitis, significantly correlate with the development of infections, for example, after surgical spinal operations. Poor oral health and associated diseases can lead to infections that potentially facilitate the formation of fistulas. This underscores the importance of good oral hygiene and regular dental check-ups to minimize the risk of oral infections and associated complications like dental fistulas.
