What should I do about red, swollen, and inflamed gums?

First, treat redness, swelling, and inflammation of the gums by removing dental calculus. Dental tartar should be removed because its rough surface can damage the gums, and it also promotes bacterial adhesion, leading to toxin production that irritates the gums. Oral medications such as metronidazole capsules may also be taken for treatment. Meanwhile, patients should maintain good oral hygiene, rinse their mouth after meals, eat a light diet, and avoid spicy and greasy foods.
