Face swollen after toothache
Facial swelling after toothache can indicate a spreading tooth or gum infection and needs prompt dental assessment.
The short answer
Tooth decay or a crack can allow bacteria to reach the pulp, causing inflammation and infection around the root. Pus may collect in the gum or facial tissues, producing swelling, tenderness, bad taste, fever, or difficulty opening the mouth.

How will a dentist assess a swollen face after toothache?
The dentist examines the tooth and face, tests the pulp and bite, and takes dental images when needed. Treatment removes the source through drainage, root canal treatment, or extraction; antibiotics may be considered when there are signs of spreading infection or systemic illness, but they do not repair the infected tooth.
What should you avoid when toothache causes facial swelling?
Do not squeeze the swelling or apply heat, and do not put aspirin on the gum. Keep hydrated, eat soft foods, use pain relief only as directed for you, and arrange urgent dental assessment.
When does facial swelling require emergency medical care?
Go to emergency medical care immediately for difficulty breathing or swallowing, swelling under the jaw or tongue, confusion, severe weakness, or rapidly spreading facial swelling. Dental care is still needed to treat the source.
What should you ask about a swollen face and tooth?
Ask whether the tooth can be saved, whether drainage is needed, what imaging shows, and which warning signs mean you should return urgently.
Frequently asked questions
Can this problem be diagnosed from symptoms alone?
Symptoms suggest possible causes, but an examination and sometimes imaging are needed to identify the dental source.
What should I avoid doing at home?
Avoid scraping, squeezing, gluing, or placing concentrated medicines directly on teeth or gum tissue.
