Tooth swelling causes and urgency
Tooth or gum swelling can result from infection, trapped food, trauma, or blocked drainage and should be assessed promptly.
The short answer
Swelling near a tooth is often a sign of inflamed or infected dental tissue and needs prompt examination to find and treat the source.
Where can swelling around a tooth or gum develop?
The swelling may be in the gum, around the root, inside the cheek, or beneath the jaw. Common causes include a dental abscess, gum infection, impacted food, erupting tooth, trauma, or a blocked salivary duct.
What can you do while waiting for a swollen tooth to be checked?
Rinse gently with warm water, keep the area clean, avoid squeezing or piercing the swelling, and use only medicines suitable for you according to their directions. Arrange dental assessment for examination, pulp tests, gum probing, and imaging when indicated.
When does tooth swelling require urgent dental or medical care?
Go to urgent dental or medical care for fever, rapidly increasing swelling, facial or neck spread, difficulty opening the mouth, swallowing, speaking, or breathing. These signs can indicate spread beyond the tooth.
What should you ask about the source of tooth swelling?
Ask where the infection or inflammation is located, whether drainage is needed, whether the pulp is involved, and which treatment will remove the source rather than only reduce swelling.
Frequently asked questions
Can tooth swelling go away by itself?
It can fluctuate or drain, but the underlying cause may remain and recur.
Does swelling always mean an abscess?
No. Trauma, gum irritation, an erupting tooth, and salivary problems can also cause swelling.
Can antibiotics fix a swollen tooth?
Medicine alone may not remove infected pulp or a trapped source. The dentist decides whether drainage or dental treatment is needed.
