One of the commonest mouth diseases is periodontitis. This disease occurs usually during middle or late life. In some cases it may result from infection due to lowered resistance within the teeth and gums. The teeth may loosen and separate, the gums becoming inflamed. Stomatitis refers to a condition characterized by inflammation of the oral cavity.
Stomatitis is an inflammation of the soft tissues of the mouth occurring as a result of mechanical, chemical, thermal, bacterial, viral, electrical, or radiation injury or reactions to allergens or as secondary manifestations of systemic disease. There are various types of this disease such as catarrhal stomatitis, chronic stomatitis, simple stomatitis, chemical stomatitis and so on.
