Jaw gum swelling
Swelling near the jaw or gum can result from plaque-related inflammation, a dental abscess, an erupting tooth, food trapped under the gum, or irritation.
The short answer
Swelling near the jaw or gum can result from plaque-related inflammation, a dental abscess, an erupting tooth, food trapped under the gum, or irritation from an appliance. The location, tenderness, drainage, and presence of fever guide the next step.
What is the difference between gum swelling and an abscess?
Gum tissue can enlarge when inflamed, while an abscess is a collection of infected fluid from a tooth or periodontal pocket. Swelling at the back of the jaw may also involve an erupting wisdom tooth, and swelling inside the cheek or under the jaw may require assessment of nearby spaces.
What should you do while a gum swelling is present?
Rinse gently with warm water, keep brushing the surrounding teeth, and avoid squeezing or puncturing the swelling. Arrange an examination for probing, tooth vitality tests, and dental X-rays; treatment may involve cleaning, drainage, root canal treatment, extraction, or gum therapy.
When does jaw or gum swelling need urgent care?
Seek urgent care for rapidly increasing swelling, facial asymmetry, fever, severe pain, reduced mouth opening, or difficulty swallowing or breathing. These symptoms can indicate spread beyond the local gum.
What should you ask about the source of the swelling?
Ask whether the swelling comes from the tooth, periodontal pocket, wisdom tooth, or soft tissue. Ask whether drainage, antibiotics for a spreading infection, root canal treatment, extraction, or periodontal treatment is indicated.
Frequently asked questions
Can I drain gum swelling myself?
No. Puncturing it can spread infection and does not treat the dental source.
Can antibiotics solve every swelling?
Antibiotics may be considered for spreading or systemic infection, but source control such as drainage or dental treatment is often needed.
