How to treat a dental abscess and what the main causes are

A dental abscess is a buildup of pus caused by a bacterial infection that develops around the root of a tooth or in the gums. This dental condition is generally painful and can seriously compromise the patient’s quality of life if not treated promptly. If left untreated, the infection can spread to surrounding tissues, leading to more serious complications. In this article, we explain what the dentist does in the case of an abscess and what the most effective prevention methods are.

1. Types of Dental Abscess ⇧

There are two main types of dental abscess: periodontal and endodontic. The former refers to an infection affecting the tooth’s supporting structures (ligament, root cementum, alveolar bone, and gum), and is linked to periodontitis and gum disease. The latter, known as a periapical abscess, affects the tip of the tooth and is caused by the necrosis of the pulp tissue inside the dental canals. It is typically associated with cavities.

2. Causes of Dental Abscess ⇧

The underlying causes of infection can vary, but the common factor is always bacterial proliferation, which invades the deeper tissues of the tooth or gums. The most common situations that trigger an abscess include:

  • Deep cavities that are left untreated, allowing bacteria to reach the dental pulp;
  • Fractures or trauma to the teeth that expose internal tissues to bacterial attack;
  • Poorly executed root canal treatments that do not follow the highest safety standards;
  • Accumulated bacterial plaque due to poor oral hygiene, leading to gingivitis and, later, periodontal disease;
  • Weakened immune system—due to stress or chronic illness—that makes the body more vulnerable to infections.

Deep cavities are among the most common causes of abscesses, making regular dental checkups and timely treatments essential to prevent the progression of bacterial infections.

Connection Between Periodontal Disease and Dental Abscess

Periodontal disease is a major factor in the development of dental abscesses due to its chronic inflammatory nature, which progressively damages the tooth’s supporting structures. Persistent gum inflammation and the formation of deep periodontal pockets allow bacteria to penetrate the gum tissue more easily, significantly increasing the risk of infections and abscesses.

Early and targeted treatment of periodontal disease at our dental practice helps prevent abscesses and maintain optimal oral health, preserving the natural function of the teeth and the patient’s overall well-being. Our specialists use advanced technology and innovative techniques to provide safe, effective, and minimally invasive treatments.

3. What Are the Symptoms of a Dental Abscess? ⇧

To identify this issue in time, it is important to recognize the characteristic symptoms, which include:

  • Severe, persistent, and throbbing pain in the affected tooth, often worsening with chewing;
  • Noticeable swelling of the gum or the area of the face near the infected tooth;
  • Heightened tooth sensitivity to temperature (hot and cold);
  • Fever, general discomfort, headache, and sometimes swollen lymph nodes;
  • Bitter taste in the mouth and persistent bad breath, indicating an active infection.

How Many Days Can a Tooth Abscess Last?

A tooth abscess can last anywhere from a few days to several weeks, depending on the severity of the infection and how quickly treatment is administered. Typically, intense pain can subside within a few days after starting an antibiotic treatment prescribed by the dentist. However, the abscess will not fully resolve without specific dental intervention such as drainage, root canal treatment, or, in severe cases, tooth extraction. It is therefore crucial to consult a dentist promptly to avoid complications and speed up recovery.

What should you do about a dental abscess? At Studio Odontoiatrico Motta Jones Rossi & Associati in Milan, we adopt a targeted and personalized approach that begins with a thorough assessment of the affected area using digital X-rays to determine the severity and exact origin of the infection. We perform abscess drainage through surgical incision to completely remove the accumulated pus and rapidly relieve pain. In addition, we prescribe specific antibiotics to fight the ongoing bacterial infection.

Daily Prevention

Preventing an abscess mainly involves measures to reduce the risk of infection. Proper and consistent oral hygiene is essential for keeping teeth and gums healthy. Key recommendations include:

  • Brushing teeth thoroughly at least twice a day with a soft-bristled toothbrush and fluoride toothpaste;
  • Using dental floss or similar tools daily to effectively remove food debris and plaque between teeth;
  • Undergoing regular professional dental cleanings to remove plaque and tartar that are hard to reach with standard home care practices;
  • Scheduling regular dental checkups, ideally every six months, to detect and treat issues such as cavities or periodontal disease early on.
