If there is a lump of flesh on your swollen gum, you should pay attention. First, maintain good oral hygiene by gently brushing your teeth and rinsing your mouth with warm salt water. Avoid eating hard, spicy, or irritating foods. See a dentist as soon as possible. The dentist will examine the condition and determine the cause. It could be due to gum infection, an abscess, or other issues. Treatment may include antibiotics if there is an infection, scaling and root planing to clean the teeth and gums, or in some cases, surgical drainage if there is an abscess. ????
