A dental abscess can be painful, worrying and, in some cases, a sign that you need urgent dental treatment. While some dental problems can wait for a routine appointment, an abscess should never be ignored, especially if you have facial swelling, severe toothache, a bad taste in your mouth or feel unwell.
At Dulwich Dental Office, we see patients with dental abscesses and dental infections at our clinic in East Dulwich, London. We provide both NHS and private dental care, helping adults, children and families get the advice and treatment they need when dental pain or swelling becomes a concern.
In this guide, we explain what a dental abscess is, the symptoms to look out for, when it may be a dental emergency, and why prompt treatment is often needed.
What Is a Dental Abscess?
A dental abscess is a pocket of pus caused by a bacterial infection. It can develop around the root of a tooth, in the gum, or in the supporting tissues around the tooth.
An abscess may form when bacteria enter the tooth or gums, often through untreated tooth decay, gum disease, a cracked tooth, trauma, or a failing filling or crown. Once bacteria reach deeper tissues, the body responds by trying to fight the infection, which can lead to swelling, pressure, and pain.
There are different types of dental abscess, including:
- Periapical abscess – usually forms at the tip of the tooth root, often due to infection inside the tooth.
- Periodontal abscess – develops in the gum or supporting structures around the tooth, often linked to gum disease.
- Gingival abscess – occurs in the gum tissue, sometimes due to trapped food or injury.
Whatever the cause, a dental abscess usually needs professional dental care. It is unlikely to resolve properly on its own, and symptoms may return or worsen if the source of infection is not treated.
Common Dental Abscess Symptoms
Dental abscess symptoms can vary from mild discomfort to severe pain and swelling. Some people notice symptoms gradually, while others experience sudden pain that becomes difficult to manage.
Common signs of a dental abscess include:
- Throbbing or constant toothache
- Pain when biting or chewing
- Sensitivity to hot or cold
- Swollen gums around a tooth
- Facial swelling or swelling of the jaw
- A pimple-like swelling on the gum
- A bad taste in the mouth
- Bad breath
- Pus or fluid draining from the gum
- A loose tooth
- Difficulty opening the mouth fully
- Fever or feeling generally unwell
- Swollen glands in the neck or jaw
It is important to remember that pain is not always a reliable measure of how serious an infection is. Sometimes an abscess may drain, causing pain to ease temporarily, but the infection can remain.
If you notice swelling, pus, a bad taste, or recurring dental pain, it is best to contact a dentist for advice.
Severe Tooth Pain: A Key Warning Sign
One of the most common symptoms of a dental abscess is severe tooth pain. This pain may feel sharp, throbbing, deep or constant. It can also spread to the ear, jaw, neck, or side of the face.
Abscess pain often becomes worse when lying down because pressure can build around the infected area. You may also find it difficult to sleep, eat or concentrate.
Pain may be triggered or worsened by:
- Biting down
- Chewing food
- Hot drinks
- Cold drinks
- Touching the affected tooth
- Pressure around the gum or jaw
If your toothache is severe, persistent, or not improving with pain relief, you should seek dental advice as soon as possible. Painkillers may help reduce discomfort temporarily, but they will not remove the cause of the infection.
At Dulwich Dental Office, we encourage patients to contact us promptly if they are experiencing severe dental pain, especially where there is swelling or signs of infection.
Swelling in the Gum, Jaw, or Face
Swelling is one of the most important symptoms to watch for with a suspected dental abscess. A small swelling around the gum can sometimes be localised, but swelling that spreads to the jaw, cheek, face, or neck may indicate that the infection is becoming more serious.
You may notice:
- A swollen gum near the painful tooth
- Puffiness in the cheek or jaw
- Tenderness under the jaw
- Swollen glands
- Tightness or pressure in the face
- Difficulty opening your mouth
Facial swelling should always be taken seriously. If swelling is increasing or spreading, urgent dental care may be needed. In rare cases, dental infections can spread beyond the tooth and gum area, which may require emergency medical attention.
If you have swelling affecting your breathing, swallowing, eye area, or ability to open your mouth, this should be treated as an emergency.
Bad Taste, Pus or Bad Breath
A dental abscess can sometimes drain into the mouth. If this happens, you may notice a sudden unpleasant taste, salty or bitter fluid, or pus around the gum.
Some patients describe:
- A bad taste that does not go away
- Fluid leaking from a spot on the gum
- Persistent bad breath
- A visible gum boil or pimple
- Relief of pressure followed by recurring symptoms
Although drainage may reduce pain for a short time, it does not mean the infection has gone. The abscess can continue to develop unless the source is properly treated.
If you have pus, a bad taste, or a gum boil, you should arrange a dental appointment. Your dentist can assess whether the tooth needs root canal treatment, drainage, periodontal treatment, or another form of care.
Fever and Feeling Unwell
A dental abscess can sometimes cause symptoms beyond the mouth. If your body is fighting an infection, you may develop a fever or feel unwell.
Symptoms may include:
- High temperature
- Chills
- Tiredness
- Headache
- Swollen glands
- Feeling weak or run down
- Nausea in some cases
Fever with dental swelling or severe pain can be a sign that the infection is spreading or becoming more difficult for the body to control. You should seek urgent dental or medical advice if you feel unwell alongside dental abscess symptoms.
When Is a Dental Abscess an Emergency?
A dental abscess may be considered an emergency if symptoms are severe, spreading or affecting your ability to function normally.
You should seek urgent dental advice if you have:
- Severe toothache that is not improving
- Facial swelling
- Swelling spreading to the jaw, neck, or eye area
- Fever or feeling unwell
- Difficulty swallowing
- Difficulty breathing
- Difficulty opening your mouth
- Persistent bleeding or pus
- A tooth that feels very loose
- Pain after dental trauma
- Symptoms that are worsening quickly
If you have difficulty breathing, difficulty swallowing, severe facial swelling, swelling around the eye, or feel seriously unwell, you should seek emergency medical help immediately.
For dental pain, gum swelling or suspected abscess symptoms, contact Dulwich Dental Office as soon as possible so our team can advise you on the next steps.
Why Urgent Treatment May Be Needed
A dental abscess usually needs treatment because the infection source remains inside the tooth, gum, or surrounding tissues. Without treatment, symptoms may worsen and the infection may spread.
Urgent treatment may be needed to:
- Relieve pain and pressure
- Drain infection where appropriate
- Prevent symptoms from worsening
- Reduce the risk of infection spreading
- Save the tooth where possible
- Protect surrounding teeth and gums
Depending on your symptoms and the cause of the abscess, your dentist may recommend different treatment options. These may include draining the abscess, root canal treatment, periodontal treatment, antibiotics in certain cases, or tooth extraction if the tooth cannot be saved.
Antibiotics alone are not always enough to treat a dental abscess. They may help control infection in some situations, but the underlying cause still needs to be managed by a dentist.
What Happens at an Appointment for a Dental Abscess?
When you visit us with a suspected abscess, our dental team will assess your symptoms, examine your mouth, and discuss your medical history. We may also take dental X-rays to check the tooth root, bone, and surrounding tissues.
Your appointment may include:
- A discussion about your pain and symptoms
- Examination of the affected tooth and gum
- Assessment of swelling or drainage
- Bite and sensitivity checks
- X-rays if needed
- Advice on pain relief and aftercare
- A treatment plan tailored to your needs
At Dulwich Dental Office, we aim to make your visit as comfortable as possible. We understand that dental abscesses can be painful and stressful, particularly if you are nervous about treatment.
Our dentists provide clear explanations and will talk you through your options before treatment begins.
Can a Dental Abscess Go Away on Its Own?
A dental abscess should not be ignored, even if the pain improves. Sometimes an abscess may burst or drain, which can reduce pressure and make symptoms feel better temporarily. However, the infection can remain and may return.
If the tooth nerve has died, pain may also reduce, but this does not mean the problem is solved. The infection can continue in the root or surrounding bone.
The safest approach is to have the area assessed by a dentist. Early treatment may make it more likely that the tooth can be saved and may help avoid more complex treatment later.
How to Reduce Your Risk of a Dental Abscess
Not every dental abscess can be prevented, but good oral care and regular dental visits can reduce your risk.
Helpful steps include:
- Brushing twice a day with fluoride toothpaste
- Cleaning between your teeth daily
- Attending regular dental check-ups
- Seeing a hygienist where recommended
- Treating tooth decay early
- Replacing damaged or leaking fillings
- Seeking advice for cracked or broken teeth
- Managing gum disease with professional support
- Reducing sugary snacks and drinks
- Wearing a mouthguard if you grind your teeth or play contact sports
Preventive dental care is a key part of what we do at Dulwich Dental Office. Our team helps patients maintain healthy teeth and gums through routine check-ups, hygiene appointments, oral health advice, and early treatment where needed.
