This sounds like a highly communicable illness called impetigo and should be treated with antibiotics.
Impetigo causes weeping sores, its the 'weeping' that is contagious. Be it via skin to skin contact, a towel or virtually anything. When the sores are fully scabbed they are not contagious, its only the liquid inside the sores that is contagious.
Canker sores are not infectious.
Nope. Cold sores are though.
Cold sores are very contagious.
Sores on the lips and mouth are most commonly caused by the herpes simplex virus (cold sores) or canker sores. Cold sores are contagious and typically appear as small fluid-filled blisters around the lips, while canker sores are not contagious and appear as painful ulcers inside the mouth. Both usually heal on their own within a week or two.
Canker sores an cold sores are not the same thing. Oral herpes is caused by a contagious virus. Cold sores can cause a lot of discomfort or pain and they affect the out side of the mouth. Canker sores are caused by bacteria and as far as I know they are not contagious. Canker sores are raise white slightly itchy masses that occuron the inside of the mouth.
You can take the chance if you like, but to be safe, don't do it. The virus that causes cold sores is very contagious when the sores are in evidence and for a period before they show. Best bet is to be cautious and don't chance spreading this painful affliction any more than you have to.
Sores in mouth are caused by many different factors. Those caused by physical injuries such as canker sores, are not contagious. However, mouth sores caused by virus or bacteria could be contagious through kissing.
