Contagious vs. Non-Contagious
Conditions such as Crohn's disease, vitamin B-12 deficiency, lupus, anemia, celiac disease, pemphigoid, irritable bowel syndrome and ulcerative colitis can all present themselves in the mouth as oral blisters. These conditions are not typically contagious, though, and dental professionals often work together with medical doctors to determine a treatment plan that will increase the healing process, as well as patient comfort and management of the condition while it's present.
Communicable conditions such as chicken pox, herpes simplex type 2 (cold sores), coxsackievirus (hand-foot-mouth disease), herpes simplex type 1 (genital herpes), HIV/AIDS, infectious mononucleosis and syphilis each can produce similar blisters in mouth tissue that are varying degrees of contagious – specifically when the blisters break open and excrete the virus. These conditions each have separate symptoms that accompany the blisters, yet share the common need to visit a medical and dental professional to receive a treatment plan for proper disease management.
