Mouth pain and swelling
Mouth pain with swelling can involve a tooth, gum, salivary gland, ulcer, injury, or jaw tissue and needs prompt assessment.
What can cause pain and swelling inside the mouth?
Mouth pain with swelling can involve a tooth, gum, salivary gland, ulcer, injury, or jaw tissue and needs prompt assessment.
What can pain and swelling tell you about your mouth?
Pain and swelling are signs, not a diagnosis. A dental abscess, gum infection, impacted tooth, trauma, salivary duct problem, ulcer, or jaw joint disorder can affect different tissues and needs a different examination and treatment.
What should you do while mouth pain and swelling continue?
Keep the mouth clean, avoid pressing the swelling, choose soft foods, and note its location, onset, triggers, fever, drainage, and any trouble opening the mouth. A clinician examines the teeth, gums, tongue, floor of mouth, salivary areas, and jaw, with tests or imaging when indicated.
When does mouth pain with swelling need prompt care?
Arrange prompt dental care for new or worsening swelling, tooth pain, pus, fever, or difficulty opening the mouth. Go for urgent medical assessment if swelling affects breathing or swallowing or spreads into the face or neck.
What should you ask about the painful swollen area?
Ask which tissue is swollen, whether there is a tooth infection or abscess, whether imaging is needed, and what treatment addresses the source.
Frequently asked questions
Can mouth swelling be treated only with pain medicine?
Pain medicine may reduce discomfort but does not identify or remove a dental or soft-tissue source.
Why might swelling return after it drains?
Drainage can lower pressure while the infected tooth or gum source remains.
