What is a Tooth Abscess?

A tooth abscess is a pocket of pus caused by a bacterial infection inside or around a tooth. It often forms when decay, trauma, or a failed filling allows bacteria to reach the pulp (the living tissue inside your tooth) or the surrounding bone and gum.

There are different types of abscesses:

Periapical Abscess:

At the tip of the root, usually due to pulp infection.

Periodontal Abscess:

In the gum and supporting bone around the tooth.

Combined:

When both occur together, especially in advanced cases.

Left untreated, an abscess can spread to surrounding tissues, cause bone loss, or lead to systemic infection. That’s why urgent care is important not just for pain relief, but also for protecting your overall health.

At The Harley Street Academy, we use advanced diagnostics and high-resolution CBCT imaging to accurately identify the source and act quickly. The goal is to stop the infection, save the tooth, and get you out of pain.

Symptoms of a Tooth Abscess

Some signs are hard to ignore, and others are more subtle. Sometimes, the nerve inside the tooth dies quietly — so you may not feel pain until the abscess is well-established. That’s why even mild symptoms, especially with a history of dental work or decay, shouldn’t be ignored. If you notice any of the following, it’s best that you get it looked at:

  • Throbbing, persistent toothache, especially if it gets worse with pressure or at night

  • Swelling in the gum, face, or jaw near a specific tooth

  • Sensitivity to heat or cold that lingers after the source is gone

  • Pain when chewing or touching the tooth

  • A bad taste in your mouth or foul-smelling breath

  • A visible pimple on the gum (also called a sinus tract) that may ooze

Fever, fatigue, or swollen lymph nodes if the infection is spreading

What Causes a Tooth Abscess?

Once bacteria enter, the body responds with inflammation and immune cells. Pus builds up as the infection progresses, and with nowhere to drain, pressure increases- causing pain and swelling. If left untreated, it can spread to surrounding tissues and even further, making early treatment critical.

A tooth abscess forms when bacteria reach the inner pulp of a tooth, usually through:

1

Deep tooth decay

that’s been left untreated

2

Cracks or fractures

 in the enamel that let bacteria in

3

Leaky fillings

or repeated dental work on the same tooth

4

Gum disease (periodontitis)

that affects the tooth roots

4

Trauma

even without visible damage, a knock can compromise the pulp

Do I need to See a Dentist for a Tooth Abscess?

Yes- always. Tooth abscesses don’t go away on their own. Even if the pain fades, the underlying infection can remain active and silently spread. This isn’t something you can treat with home remedies or over-the-counter pain relief alone. Antibiotics may offer temporary relief, but they won’t address the source, which is the infected pulp inside the tooth.

Left untreated, abscesses can lead to:

  • Severe pain and facial swelling
  • Damage to nearby teeth or bone
  • Sinus involvement or jaw stiffness
  • Systemic infection, which in rare cases can become life-threatening

The earlier you’re seen, the easier it is to treat and the better the chance of saving your natural tooth.

How we treat abscessed teeth at Endo Academy

At Endo Academy, abscess treatment is handled with precision, experience, and a calm, considered approach. Our goal is always to eliminate the infection, preserve your natural tooth wherever possible, and relieve your discomfort quickly and safely.

Specialist Diagnostics

We start with a detailed clinical exam and high-resolution CBCT 3D imaging to assess the extent of the infection. This allows us to confirm whether a root canal is appropriate and rule out complications like fractures or bone loss.

Microscope-led root canal treatment

For most abscesses, root canal treatment is the gold standard. Under high magnification, we clean out the infected pulp, disinfect the canals using modern protocols (including laser-assisted irrigation), and seal them to prevent bacteria from returning.

Laser Disinfection

We use state-of-the-art laser technology to thoroughly disinfect the injected canal once accessed. This is next-gen technology which makes disinfection more predictable.

Surgical intervention if needed

In rare cases, if the infection is persistent or located at the root tip in a hard-to-access area, a minor surgical procedure (apicectomy) may be recommended. We’ll walk you through this option only if needed.

Follow-up and long-term care

You’ll leave with clear aftercare instructions, a full written report, and a plan for final restoration, usually a crown, to protect the tooth long term. Our team is here if you have questions or need reassurance at any point in your recovery.

Costs & Payment Options

Clear, fixed fees — no surprises. At your consultation, we confirm the exact price before treatment and outline what’s included:

  • Specialist assessment and targeted imaging (CBCT when indicated)
  • Rubber dam isolation, microscope-led treatment
  • Advanced irrigation and laser-assisted disinfection
  • Obturation and a high-quality temporary or permanent restoration
  • A written report for you and your dentist

 

What’s not included: the final crown or onlay. We’ll coordinate this with your dentist post-treatment.

Retreatment & complex cases: fees reflect the extra time to remove posts, negotiate calcified canals, or manage brokeninstruments. You’ll get a clear plan either way.

NHS vs private: NHS access to specialist endodontics is limited, especially for molars and complex cases. Private treatment gives faster access, advanced imaging and protocols, and predictable appointment times. If you have questions on finance or staged care, ask us — we’ll map your options in plain English.

FAQs

Answering our most commonly asked questions.

Yes. If you’re experiencing severe pain, swelling, or a bad taste in your mouth, it could indicate a spreading infection. Left untreated, abscesses can lead to complications. We recommend seeking prompt care, even same-day treatment where appropriate.

Not permanently. Antibiotics may temporarily calm the infection or buy time, but they don’t remove the source—infected tissue inside the tooth. The only lasting solution is to physically clean, disinfect, and seal the canals (via root canal treatment) or remove the tooth.

Not necessarily. Many abscessed teeth can be saved with timely root canal treatment. We assess each case carefully and recommend extraction only if the tooth is fractured, non-restorable, or poses a risk to your health.

No. With modern anaesthesia and careful technique, the procedure itself is comfortable. Most patients feel significant relief from the pain they had before treatment. Post-treatment tenderness is common for a couple of days but is manageable with pain relief.

Most people return to normal eating and activities within a few days. The area may be tender initially, but full healing—especially if there was swelling—can take a few weeks.

Swelling that’s localised near a tooth, especially with pain or a bad taste, often points to an abscess. Facial swelling, warmth, or difficulty opening your mouth may signal a more serious spread of infection. If in doubt, get assessed quickly—especially if you develop fever or feel unwell.

If the tooth isn’t fully sealed or bacteria remain, a reinfection is possible. At Endo Academy, we use advanced imaging and disinfection techniques to reduce this risk. We’ll also advise on long-term care, including any restoration needed to protect the tooth.

We don’t recommend it. Abscesses rarely go away on their own and can worsen quickly. If in doubt, it’s safest to get checked early.

No. Attempting to drain or pop a dental abscess at home can worsen the infection, introduce more bacteria, or delay proper care. Always seek professional treatment. If the abscess drains spontaneously, it still needs full cleaning and disinfection to resolve the issue at its source.

An abscess is usually caused by bacteria entering the tooth through deep decay, a crack, trauma, or failed dental work. Once bacteria reach the pulp (nerve space), the body responds with inflammation and pus formation. Left untreated, it can spread to the bone or surrounding tissues.

A gum (periodontal) abscess starts in the space between the tooth and gum, usually due to gum disease. A tooth (periapical) abscess originates from inside the tooth, typically from an infected pulp. While symptoms can overlap, treatment approaches differ. We use specialist tests and imaging to diagnose the source accurately.

A&E should only be used if the infection is severe—such as swelling affecting breathing or vision, or if you’re experiencing fever, chills, or spreading redness. For most abscesses, urgent dental care is the best first step. At Endo Academy, we can usually see patients promptly and start treatment to relieve pain and stop progression.
