What is the term for inflammation of the mouth?

Stomatitis is the correct term for inflammation of the mouth. This condition encompasses inflammation of the mucous membrane inside the mouth, affecting various structures such as the cheeks, gums, tongue, lips, and roof or floor of the mouth. Symptoms may include pain, swelling, and sores, which can result from various causes including infections, irritants, or systemic conditions.

Glossitis specifically refers to inflammation of the tongue, rather than the entire mouth, and pharyngitis relates to inflammation of the pharynx, which is part of the throat. Oralitis is not a recognized medical term for inflammation of the mouth and does not appear in medical literature. Thus, stomatitis is the most accurate and widely accepted term for this condition.
