Swollen gums, redness or tenderness are common complaints. This page outlines typical causes, practical supportive measures you can try at home, and when a dental assessment is recommended.
How swelling can appear and accompanying signs
Gum swelling may affect a single area or a larger region. It often presents as puffiness, redness, tenderness to touch, bleeding on brushing, bad breath or a shiny surface on the gum. Swelling can be accompanied by tooth pain, discomfort when biting, or sensitivity when food contacts the gum.
Common causes and triggering factors
Many factors can lead to swollen gums: plaque and poor oral hygiene that cause gingivitis; tooth decay, periodontal infections or dental abscesses that produce more localized, pronounced swelling; trauma, ill‑fitting dentures or tartar accumulation that irritate tissues. Hormonal changes (for example during pregnancy), smoking, some systemic conditions and, more rarely, medication-related gum overgrowth can also contribute.
Supportive measures you can try at home
For short‑term relief focus on oral hygiene: brush gently with a soft‑bristled toothbrush, clean between teeth with floss or interdental brushes, and rinse gently with warm salt water in moderation. Avoid vigorous rinsing or pressing directly on the swollen area. These steps are supportive; if the swelling does not improve within 1–2 weeks or worsens, see a dental professional.
When to seek professional or emergency care
A dental evaluation is usually the next step; your dentist may refer you to a periodontist or an oral and maxillofacial specialist if needed. Seek urgent care if the swelling increases rapidly, spreads to the face or neck, causes difficulty swallowing or breathing, is accompanied by a high fever, or if you notice a visible mouth abscess. For routine cases, a dentist will perform an exam, periodontal assessment and, if necessary, imaging to determine the cause.
