Dental abscess symptoms: when to get urgent help in Glasgow

What a dental abscess is

An abscess is a build-up of pus caused by a bacterial infection. In the mouth it usually forms in one of two places. A periapical abscess develops at the tip of a tooth's root, most often when decay, a crack or an old filling lets bacteria reach the soft tissue inside the tooth. A periodontal abscess forms in the gum beside a tooth, usually linked to gum disease or something trapped below the gum line.

In both cases the body tries to wall off the infection, and a pocket of pus builds up under pressure. That pressure is why abscess pain is so often described as throbbing or pounding, and why it can feel worse when you lie down. The pus has nowhere to go, and neither do the bacteria, until a dentist drains it and deals with the cause.

Symptoms to look out for

An abscess does not always look dramatic from the outside, especially early on. Common signs include intense, throbbing pain in a tooth or the gum, which may come on quite suddenly and steadily worsen, pain that spreads to your ear, jaw or neck on the same side, and pain that is worse when you lie flat, often bad enough to keep you awake.

You may also notice a tooth that is tender to bite on, or feels slightly raised or loose, sensitivity to hot or cold food and drink, a red, swollen or shiny area on the gum, sometimes with a visible bump, swelling in your face or cheek, a bad taste or smell in your mouth, or feeling hot, shivery and generally unwell.

Sometimes an abscess bursts by itself. The pain can ease dramatically and you may notice an unpleasant, salty taste as the pus drains. It is tempting to take that relief as a sign the problem has sorted itself out. It has not. The infection is still there, the cause is still there, and it will almost always flare up again, often worse than before.

Why an abscess will not fix itself

An abscess is not like a cold that your immune system can clear given time. The infection sits inside a tooth or a pocket in the gum where your body's defences cannot properly reach it. Treatment means two things: draining the pus, and removing the source of the infection. Depending on the tooth, that might mean root canal treatment, taking the tooth out, or draining and cleaning the gum.

It is also worth knowing that antibiotics alone are not a cure. NHS and Scottish dental guidance is clear on this point. Antibiotics have a role when an infection is spreading or making you unwell, but they do not remove the cause, and taking them without dental treatment usually just delays the inevitable. Please do not be tempted by leftover antibiotics in a drawer. They may be the wrong drug at the wrong dose, and they can mask symptoms while the infection quietly continues.

Left untreated, a dental abscess can spread into the jaw and the soft tissues of the face and neck. Serious complications are rare, but they are genuinely dangerous when they happen, which is why the red flags further down this page matter.

Safe ways to cope while you arrange care

None of these will cure an abscess, but they can make the hours before you are seen much more bearable. Take painkillers if you need them. Paracetamol or ibuprofen can both help, taken exactly as the packet directs. Ibuprofen is not suitable for everyone, so check with a pharmacist if you are unsure, and never take more than the stated dose because the pain is severe. Do not give aspirin to anyone under 16, and never hold aspirin against the gum or tooth. It does not work that way and it can burn the soft tissue.

Avoid very hot or very cold food and drink if they trigger the pain, stick to soft foods, and chew on the other side of your mouth. Use a soft toothbrush and go gently around the sore area, but keep the rest of your mouth clean.

Sleep propped up on an extra pillow or two, because lying flat increases the pressure and often makes the throbbing worse. A cool compress held against the outside of your cheek can take the edge off swelling, but avoid hot water bottles or heat pads on your face. And do not squeeze, pierce or try to burst the abscess yourself, as you risk pushing the infection deeper. Think of all of this as holding the line, not solving the problem.

When it is an emergency: A&E and 999

Most dental abscesses are urgent rather than life-threatening, and the right place for them is a dentist. But there are situations where the infection or injury needs hospital care immediately. Go to A&E, or call 999, if you or the person you are caring for has any of the following: difficulty breathing or difficulty swallowing, including struggling to swallow your own saliva, swelling that is spreading towards the eye or down the neck, a high temperature alongside facial swelling, difficulty opening your mouth more than a couple of finger-widths, especially if it is getting worse, serious trauma to the face, mouth or jaw, or bleeding that will not stop.

These signs can mean the infection is spreading beyond the tooth towards the airway or deeper tissues, and that needs hospital treatment without delay. Do not wait to see if it settles overnight.
