Cold sores or fever blisters are normally caused by the herpes simplex virus. This virus often takes place around the lips and mouth area. They appear to be red blisters which are often painful and annoying.It's pretty much kinda like herpes. You can get it from someone who has it. Both herpes simplex virus 1 (HSV-1) and herpes simplex virus 2 (HSV-2) cause herpes complex.
FMD (foot and mouth disease) is a viral disease of cloven-hooved animals that causes blisters in the mouth and around the coronary band. FMD is found in these animals because the virus is trophic (specific) for the cell markers exhibited on the cells of the mouth and coronary band in cloven-hooved animals.
A skin infection similar to impetigo but that only presents with redness around the mouth is perioral dermatitis.

If they on the outside of your mouth (ie. around your lip) they might be cold sores (oral herpes). If they are inside your mouth and hurt they might be canker sores and will go away by themselves within 4-14 days.
Cold sores are also called fever blisters.
Saliva.
Avoid food or beverages that are too hot. If blisters on the roof of the mouth are appearing, a cause should be determined. Enjoin with a medical professional to get to the root of the problem.
