Doctor formulated mouthwashes and oral rinses prepared for your  mouth sores and oral ulcerations.

The technical term for oral ulceration is stomatitis. Confusing I know! Sounds like it should have something to do with the stomach, right? The term refers to irritation of the mucous membranes (mucositis) in the affected areas. 

Oral ulceration can be caused by a number of disease states and can often be recurrent. 
Oral ulceration: 
         * can be present in patients undergoing:
               * Chemotherapy
               * Radiation
               * Bone-marrow transplant
         * can occur in disorders such as:
               * oral infection
               * allergic stomatitis
               * aphthous stomatitis (aphthous ulcer)
               * Behcet's Disease
          * can appear in AIDS patients

These sores can be disabling to the patient, interfering with normal activities such as speaking and eating.
