Understanding Dental Abscesses and Why Prompt Treatment Matters

A tooth abscess is a pocket of infection caused by bacteria that have entered the tooth or surrounding tissues. An abscess can be painful and may cause swelling of the gums, face, or jaw. If left untreated, the infection can spread and lead to more serious health problems.

At Total Dentistry, Dr. Christopher Omeltschenko performs a comprehensive examination to determine the source of the infection and recommend the most appropriate treatment to relieve pain, eliminate the infection, and preserve your oral health whenever possible.

What Is a Tooth Abscess?

A tooth abscess is a bacterial infection that develops when the nerve inside a tooth dies or bacteria spread into the tissues surrounding the root of the tooth.

The infection often begins inside the tooth and eventually extends into the bone around the root, where it forms a collection of pus called an abscess.

Although some abscesses are extremely painful, others produce only mild discomfort—or no pain at all—until the infection becomes more advanced.

What Causes a Tooth Abscess?

A tooth abscess is most commonly caused by:

• Untreated tooth decay (cavities)
• A cracked or fractured tooth
• A dead or infected tooth nerve (necrotic pulp)
• Previous dental trauma
• A leaking filling or crown
• Advanced gum disease

Without treatment, bacteria continue to multiply and the infection may spread beyond the tooth.

Signs and Symptoms

Symptoms of a tooth abscess may include:

• Severe, throbbing tooth pain
• Swelling of the gums, face, or jaw
• Pain when biting or chewing
• Sensitivity to hot or cold
• A bad taste or unpleasant drainage in the mouth
• A small pimple or bump on the gums (gum boil)
• Swollen lymph nodes
• Fever or feeling generally unwell

Some abscesses drain on their own, temporarily relieving pain. However, this does not mean the infection has resolved.

When Should You See a Dentist?

A tooth abscess should be evaluated as soon as possible.

You should contact our office immediately if you experience:

• Facial swelling
• Severe tooth pain
• Swelling of the gums
• Drainage of pus
• Fever
• Difficulty swallowing or opening your mouth

If you develop difficulty breathing or significant swelling affecting your airway, seek emergency medical care immediately.

How Is a Tooth Abscess Diagnosed?

Determining the source of an abscess requires a thorough examination.

During your visit, Dr. Omeltschenko may evaluate:

• Digital X-rays
• Clinical photographs
• Swelling and drainage
• The health of the tooth’s nerve
• Existing fillings or crowns
• Gum health
• Bite and surrounding teeth

Identifying the underlying cause allows us to recommend the treatment that offers the best long-term outcome.

What Happens If a Tooth Abscess Is Left Untreated?

A tooth abscess will not heal on its own.

Without treatment, the infection may lead to:

• Increasing pain
• Progressive bone loss
• Damage to surrounding teeth
• Facial swelling
• Spread of infection into nearby tissues
• Tooth loss
• Serious medical complications in rare cases

Prompt treatment helps prevent these complications and often improves the chances of saving the tooth.

Possible Treatment Options

Treatment depends on the cause and severity of the infection.

Possible treatment options include:

• Root Canal Therapy – to remove the infected nerve tissue, eliminate the infection, and preserve the natural tooth whenever possible.

• Dental Crown – often recommended after root canal therapy to strengthen and protect the tooth.

• Tooth Extraction – when the tooth cannot be predictably restored or the infection has caused extensive damage.

• Antibiotics – may be prescribed when swelling or the infection has spread beyond the tooth. Antibiotics help control the infection but do not eliminate the source. Definitive dental treatment is still necessary.

Whenever possible, our goal is to preserve your natural tooth. If a tooth cannot be saved, we will discuss replacement options such as a dental implant or bridge.
