Why do gums swell and pain
Swollen, painful gums usually reflect inflammation from plaque, irritation, infection, or a trapped food particle.
Why can swollen gums become painful?
Swollen, painful gums usually reflect inflammation from plaque, irritation, infection, or a trapped food particle.
How does inflammation change the gum tissue?
Gum tissue becomes red, puffy, tender, or prone to bleeding when inflammatory fluid enters the gingiva. Plaque along the gum margin is common, but a sharp edge, ill-fitting restoration, erupting wisdom tooth, abscess, or some medicines can produce a similar appearance.
What can reduce irritation while your gums are sore?
Brush gently with fluoride toothpaste, clean between the teeth, and rinse with lukewarm water while avoiding tobacco and hard foods that irritate the area. Do not puncture a swelling or place aspirin directly on the gum; a dentist may remove calculus, flush a pocket, treat decay, or drain an abscess after examining the source.
When should painful gum swelling be examined?
Arrange an examination if swelling persists, recurs, bleeds easily, causes bad taste, or is linked with toothache or looseness. Seek urgent dental care for facial swelling, fever, difficulty swallowing, difficulty breathing, or swelling that is spreading.
What could your dentist find during the examination?
Ask whether the swelling is gingivitis, periodontal disease, a local injury, or an infection from a tooth, and what the examination shows. Ask which cleaning, filling, root canal, periodontal treatment, or medicine is appropriate and how to prevent recurrence.
Frequently asked questions
Can food stuck between teeth make a gum swell?
Yes. A trapped particle can press on the papilla between teeth and irritate it; gentle interdental cleaning may remove the trigger, but persistent swelling needs examination.
Does gum swelling always mean an abscess?
No. Plaque inflammation and mechanical irritation can swell the gums, while an abscess is an infection that may cause localized pain, pus, or a bad taste.
