Tooth decay, also known as dental caries is one of the most common dental problems worldwide. It occurs when the hard surface of the tooth is damaged due to the action of acids produced by bacteria in the mouth. If left untreated, tooth decay can lead to pain, infection, and even tooth loss. The adenoids and tonsils get enlarged when they get infected with bacteria or when the body may overreact to an allergen causing infection and inflammation. Mostly they return back to their original size once the infection is over, however in some cases they tend to remain enlarged when infections are frequent or chronic. Although some amount of enlargement is considered normal in preschool kids but when grossly enlarged, tonsils and adenoids cause certain ailments.
