【2026 Gum Swelling Solutions】5 Common Causes + Relief Methods from Dentists

💡Quick Answer
Gum swelling are most commonly caused by periodontitis from plaque buildup. Other common causes include tooth decay infection, wisdom tooth pericoronitis, food impaction, and weakened immunity.
Mild cases can be relieved with a warm saltwater rinse (half a teaspoon of salt in a cup of warm water, 2–3 times daily) and gentle cleaning with a soft-bristled toothbrush.
However, if swelling persists beyond 3–5 days, or is accompanied by fever, facial swelling, or pus, see a dentist within 24 hours to prevent the infection from spreading.
