What can cause swelling at the back of the mouth?
A swollen gum behind a back tooth can reflect inflammation, food trapping, wisdom-tooth eruption, decay, or infection.
What determines the cause of back gum swelling?
The dental subject depends on the tissues involved, the timing, and the symptoms found during examination. A dentist may inspect the teeth and gums, test sensitivity or biting, and use an X-ray when the roots, bone, or an unerupted tooth needs assessment.
How can you care for swollen gum at the back?
Keep the area clean with gentle brushing and suitable interdental cleaning, avoid experimenting with acids, powders, or force, and record what changes the symptom. Bring your medicines and relevant health history to the appointment.
When should back gum swelling receive dental care?
Arrange dental care for a persistent, worsening, painful, bleeding, loose, or swollen area. Seek urgent help for facial swelling, fever, uncontrolled bleeding, injury, or difficulty breathing or swallowing.
What should you ask about swelling at the back?
Ask what structure is affected, what findings support the diagnosis, whether an X-ray or other test is needed, and which treatment or home-care step fits your tooth, gum, bite, and restorations.
Frequently asked questions
Can a photograph diagnose it?
