Facial Swelling

Facial swelling with dental pain can indicate infection; breathing, swallowing, eye, or mouth-opening problems need emergency help.

[1][2]

The short answer

Facial swelling with dental pain can indicate a dental infection, while difficulty breathing, speaking, swallowing, or opening the mouth is an emergency.

What causes a swollen face?

Dental infection is one cause. An abscess may follow a tooth problem, while infection around a partly erupted wisdom tooth can also produce local pain and swelling. Trauma and post-procedural problems are other emergency categories.

What relief is safe tonight?

Keep brushing with fluoride toothpaste at least twice daily and clean between the teeth every day with floss or interdental brushes. A dental abscess needs dental treatment rather than home care alone.

How is the source of swelling found?

Visual inspection and palpation are initial ways to look for redness, swelling, pus, tooth discolouration, or gum damage. Dental radiographs can show caries, an abscess, bone loss, or an erupting third molar that is not obvious on inspection.

[1][2]

How is dental swelling treated?

An abscess is treated by draining the pus. If a tooth caused it, treatment may be root canal treatment or removal of the tooth. Local anaesthetic prevents pain during the procedure; painkillers and sometimes antibiotics follow.

How can dental infections be prevented?

Brush with fluoride toothpaste at least twice a day, spit rather than rinse, clean between the teeth daily, and replace the toothbrush every two to three months. Prompt treatment limits the chance of infection spreading.

[1][2]

When is facial swelling an emergency?

Call emergency services or go to an emergency department for difficulty breathing, speaking, or swallowing, a swollen or painful eye, sudden sight problems, marked mouth swelling, or difficulty opening the mouth.

Frequently asked questions

Can facial swelling from an abscess go away without treatment?

An abscess needs dental treatment to drain the pus and address the tooth or infection causing it; untreated dental emergencies can spread into deeper spaces.
