Dental Abscess

A dental abscess is a bacterial infection that causes pus to build up in various areas of the mouth. Painful and potentially serious if not treated promptly, it can affect the gums, bone, or tooth root. There are three main types of dental abscesses:

• Gingival abscess : The infection develops directly on the gum, without reaching the alveolar bone. This is generally the earliest stage and the easiest to treat.
• Periodontal abscess : The infection originates in the gum, near the alveolar bone. It is most often the result of a periodontal pocket—that is, a recession of the gum—that was not treated in time.
• A periapical abscess : The infection forms at the tip of the tooth root. When a tooth is decayed or fractured, bacteria can penetrate the dentin and then spread to the dental pulp, the inner part of the tooth that contains nerves and blood vessels. This is the most common type of abscess seen in dental practices.

The main cause of dental abscesses is untreated tooth decay, which is often invaded by bacteria. This is referred to as deep decay: an advanced lesion of the tooth that reaches the inner layers. However, dental abscesses can be caused by other factors such as:

• dental trauma
• an infection in a wisdom tooth
• a periapical abscess: an infection that forms at the root of the tooth
• A periodontal abscess: an infection of the supporting tissues around the tooth that leads to bacterial spread and pus accumulation.

The development of an abscess is often due to a fear of visiting the dentist. It is important to act quickly if you have a dental abscess before the inflammation turns into an emergency. Indeed, it can lead to serious complications, such as sepsis.

The abscess may be the result of periodontal disease, untreated chronic periodontitis, or treatment for chronic periodontitis. It may be caused by a foreign body in the periodontal pocket or damage to the root, promoting the presence of bacteria and the formation of a pocket of pus. Treatment must be prompt and comprehensive in order to address the causes of the abscess and prevent more serious complications.

The appearance of a dental abscess is accompanied by one or more symptoms, which are aggravated by lying down and may quickly become more severe. These symptoms include:

• throbbing pain in the tooth or gum
• difficulty opening the mouth
• cervical lymphadenopathy (inflammation of the lymph nodes in the neck)
• pain when chewing and swallowing
• increased tooth sensitivity, and sometimes fever accompanied by fatigue
• sleeplessness due to pain

To relieve the pain and symptoms associated with a dental abscess, a comprehensive periodontal approach is necessary. To avoid recurrence and prevent more serious conditions, it is crucial to provide appropriate dental care that addresses the underlying causes and employs treatments tailored to each type of abscess.

A dental abscess does not resolve on its own. Without treatment, the infection can gradually spread to nearby tissues—including the gums, jawbone, and cheek—and cause lasting damage to the affected area. Ultimately, this can lead to partial destruction of the alveolar bone, the formation of a dental cyst, or even tooth loss. This is precisely what we aim to prevent at Sana Oris by promoting prompt treatment.

In more advanced cases, the infection can spread beyond the oral cavity and affect other tissues in the neck or face, leading to cervicofacial cellulitis, which requires urgent medical attention. While these cases are rare, they serve as a reminder that a dental abscess should always be treated without delay.

When should you seek emergency care?

It is advisable to seek medical attention promptly as soon as persistent tooth pain develops. Certain symptoms require immediate consultation: severe pain that worsens when lying down and does not respond to pain relievers, swelling of the face or neck, swollen lymph nodes, difficulty opening the mouth or swallowing, or a fever accompanied by fatigue. At Sana Oris, dental emergencies are treated as a priority: as soon as you call, our team will assess your situation and offer you the earliest available appointment for a diagnosis and prompt treatment.

In the vast majority of cases, a dental abscess is preventable. Thorough oral hygiene, regular visits to the dentist, and prompt treatment of the first signs of tooth decay are enough to significantly reduce the risk of infection. At Sana Oris, prevention is at the heart of our approach: we support each patient over the long term with personalized care designed to preserve their oral health for years to come.

Daily Oral Hygiene

Brushing your teeth twice a day with an appropriate toothbrush and fluoride toothpaste is the first line of defense against dental infections. This should be supplemented by daily flossing or the use of an interdental brush, which are essential for removing bacterial plaque from areas that the toothbrush cannot reach. These areas—the spaces between the teeth and the gum line—are precisely where abscesses form.

Regular checkups and preventive screenings

Visiting your dentist once or twice a year allows for the early detection of any issues before they develop into an infection. During each checkup, our practitioners at Sana Oris perform a comprehensive clinical examination, supplemented if necessary by an X-ray, to identify lesions invisible to the naked eye. Professional scaling, performed during this visit, removes accumulated tartar, which provides a breeding ground for the bacteria responsible for gum and periodontal abscesses. This regular follow-up also provides an opportunity for personalized guidance on oral hygiene practices tailored to each patient’s specific needs.

Early treatment of cavities

Untreated tooth decay is the main route through which bacteria enter the dental pulp, and is therefore one of the most common causes of periapical abscesses. Treating a cavity at an early stage, when it is still superficial, is a simple, quick, and minimally invasive procedure that prevents progressive deterioration that can lead to nerve necrosis and infection. That is why we recommend not waiting to see a dentist as soon as pain or unusual sensitivity appears: the earlier the cavity is treated, the simpler the procedure and the better the chances of saving the tooth.

The intervention of a dentist or stomatologist is necessary to treat an abscess, as this infection does not heal on its own.

Treating a tooth abscess

To treat a periapical dental abscess, a thorough examination of the oral cavity is required, which may be supplemented by X-rays. The dentist or stomatologist then drains the abscess to remove the pus it contains. This procedure is performed under local anesthesia in two stages:

• Preliminary cleaning of the tooth’s canals containing the infected tissue—that is, the dental pulp—all the way to the tip of the root.
• Applying a paste in place of the removed pulp to prevent the formation of a new abscess

When an abscess develops in the gum, it is referred to as a gingival abscess. In this case, the abscess in the gum is incised and drained. The space between the tooth and the gum must be cleaned at the same time.

In the most advanced cases of dental abscesses, tooth extraction may be necessary.
A dental abscess must be treated quickly: our clinic has many slots available to take care of you quickly.

Pain and Anxiety Management

Fear of the dentist is a reality that we take fully into account at Sana Oris. In fact, it is one of the main reasons why people wait too long to seek treatment for a tooth abscess, allowing the infection to worsen when early intervention would have been sufficient. Our approach is specifically designed to overcome this barrier.

Every procedure is performed under appropriate local anesthesia to ensure optimal comfort throughout the treatment. Before the procedure, our practitioners take the time to explain each step and answer patients’ questions: understanding what is going to happen is often the key to alleviating anxiety.

Our team is specially trained in stress and pain management. From the very first contact, we tailor our care to each patient, taking into account their fears and anxiety levels, to ensure that the session proceeds under the best possible conditions. The goal is simple: to ensure that every patient, even the most reluctant, leaves with an experience that has helped them overcome their fears.

With treatment, the pain caused by the abscess subsides quickly until the infection clears up. In cases where the tooth did not need to be extracted, a root canal may be performed to restore the tooth.

After treatment for a dental abscess, we recommend that you see the dentists at your Sana Oris dental clinic on a regular basis. This is to ensure that the results of the treatment are maintained.

The special care we take to prevent periodontal disease allows us to treat conditions early on, without waiting for the complications and pain associated with untreated conditions.

To prevent recurrence, it is recommended that you see your dentist regularly and practice good oral hygiene, including brushing two to three times a day.

The cost of treatment depends on the procedures required to treat the abscess. Your dentist and their team will provide you with information about prices during your consultation.
