Glossitis is redness and swelling (inflammation) of the tongue.
Possible causes of glossitis include an allergy or infection, an injury to the
tongue, and nutritional deficiencies.
Although most cases of glossitis are minor and can be treated at
home, symptoms can cause problems with chewing, swallowing, or speaking. Glossitis
may also cause trouble breathing, if swelling is severe. If breathing
difficulties develop, emergency medical care is required.
