What to do if…
you have facial swelling from a tooth problem that is spreading

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

Facial swelling from a tooth problem can be urgent, especially if it is spreading. If you are finding it hard to breathe, speak or swallow, have swelling near your eye or vision changes, have a lot of swelling inside your mouth, or cannot open your mouth properly, call 999 or go to A&E now; do not drive yourself.

Do not do these things

  • Do not “wait and see” if the swelling is getting bigger, moving under your jaw or into your neck, or you feel increasingly unwell.
  • Do not try to squeeze, lance, drain, or pop anything in your gum, mouth, or face.
  • Do not use heat as a way to push through or delay urgent assessment.
  • Do not lie flat if the swelling feels like it is progressing; stay more upright while getting help.
  • Do not take someone else’s antibiotics or leftover antibiotics.
  • Do not exceed painkiller doses or mix products that contain the same ingredient, such as more than one paracetamol product.
  • Do not go to a GP surgery expecting dental treatment for an abscess; use urgent dental care or emergency care depending on symptoms.

What to do now

  1. Check for emergency signs now. Call 999 or go to A&E if you have any of these:

    • finding it hard to breathe, speak, or swallow
    • drooling or being unable to swallow saliva
    • swelling under the jaw, in the neck, or tightness that is getting worse
    • a swollen or painful eye, swelling spreading towards the eye, or any eyesight problem
    • a lot of swelling inside your mouth
    • finding it hard to open your mouth, especially if it is worsening

  2. If you do not have those emergency signs, get urgent dental help today.

    • Call your dental practice and say: “I have facial swelling from a tooth problem and it seems to be spreading.”
    • If your practice is closed, listen to its answerphone message for urgent or out-of-hours instructions.
    • If you cannot reach a dentist, use the official urgent dental route for where you are: NHS 111 in England, NHS 111 Wales or your local dental helpline in Wales, your dental practice or local NHS board advice in Scotland, or emergency dental services in Northern Ireland.

  3. While arranging help, reduce risk and stay stable.

    • Sit upright and keep your head raised, including when resting.
    • Take over-the-counter pain relief only as directed on the label.
    • Avoid very hot or very cold food and drink if it makes the pain worse.
    • Eat cool, soft food on the other side of your mouth if you need to eat.
    • Use a soft toothbrush and avoid pressing on the swollen area.

  4. Be ready to describe the key facts.

    • when the swelling started and how quickly it is changing
    • where the swelling is now, especially if it is near the eye, under the jaw, or in the neck
    • whether you can breathe, speak, swallow, open your mouth, and see normally
    • fever, chills, feeling very unwell, bad taste, drainage, or worsening pain
    • medicines you take, allergies, pregnancy, diabetes, immune suppression, or other major health conditions

  5. If symptoms escalate while you are waiting, switch to emergency care.

    • Call 999 or go to A&E if any emergency sign appears.
    • Do not drive yourself to A&E; ask someone to take you or call 999 for an ambulance.

What can wait

  • You do not need to decide right now whether you will need extraction, drainage, root canal treatment, or antibiotics.
  • You do not need to identify the exact tooth with certainty before asking for help.
  • You do not need to solve work, travel, money, or diary problems before seeking urgent advice.
  • You do not need to judge whether you are “overreacting”; spreading facial swelling is enough reason to ask for urgent dental assessment.

Important reassurance

Facial swelling from a tooth problem can feel frightening, especially when it spreads faster than expected. Taking it seriously and getting urgent help is a sensible safety step, not a failure or an overreaction.

Scope note

These are first steps only to help you stay safer and reach the right service quickly. Later decisions may need a dentist, urgent dental service, or hospital team after assessment.
