Mouth sores are blisters that appear in any part of the mouth and vary in appearance and size. Some are raised and some are filled with fluid while others are like craters or ulcers which appear white and have the deepest indentation in the center. But what are the things the causes of mouth sores? Well generally, mouth sores may be caused by mouth injury or stress, inflammatory disease or infection.

Mouth injury or irritation happens in different situations like accidentally biting down on the inside of the cheek, new dental braces which are very abrasive, a wrong way of brushing the teeth or anything that pierces or irritates any part of the mouth causing bacteria to build up in those areas. Since the mouth has such delicate parts and the thinnest skin, it is easily irritated even at the slightest abrasions. If the irritation is not properly handled when it starts, bacteria will begin to develop causing an infection that will lead to mouth sores. Another indirect cause to mouth injury is very acidic food which causes an imbalance in the mouth causing irritation.

Another cause of mouth sores are infections. The most common infection which cause mouth sores is the virus that causes chicken pox or shingles called herpes zoster. The blisters brought about by chicken pox choose to pop-up in any part of the body.  When these appear in the mouth, it will automatically cause multiple mouth blisters and multiple mouth sores.

Aside from viruses, bacterial infection is another reason for mouth sores. These come from decaying teeth which if not treated spread to the gums and the other surrounding parts of the mouth. Bacterial infection that spreads from decayed teeth can cause the tongue, inside cheeks and even the gums to be infected and form a pocket or abscess. Inflammatory disorders are also one of the attributes causing mouth sores. This may be an allergic reaction which makes the body react and create blisters. When the thin layer of the blister is subjected to pressure, it will burst creating an abscess which in turn would cause the bacterial infection resulting to mouth sores.

Observing proper mouth hygiene and keeping in check your food intake is the best way of prevention than to treat the mouth sore. In this way, you will be able to avoid the painful situation of having a mouth sore which might only be a small infection but can lead to weakness and not being in full health condition.
