Aphthous stomatitis, or also known as mouth blister, is a disease of the oral cavity. Its symptom is the emergence of small, sometimes purulent, blisters. From mouth blisters suffer people of all ages and both sexes, but most susceptible to the occurrence of blisters are children.

Blisters are small red spots which are sometimes white and shallow ulcers (as big as a grain of lentil) in the oral cavity, where the tissues are soft (inside of the cheeks or lips, on and under the tongue, the back of the throat, soft palate and tonsils). If there is a more serious infection, blisters may be purulent. Usually they last from 4 to 14 days (the disease is expressed in the disappearance of some and the emergence of other blisters) and do not appear more than 4 at once. Blisters occur in men of all ages but they are especially characteristic for children.

There are many different causes for the occurrence of mouth blisters. Here are some of them:

-Weak immune system and subsequent infection after the entry of something into the mouth. Some experts believe that the virus Herpes Simplex Labialis which is the cause of herpes leads to the occurrence of mouth blisters;
-When biting your tongue or the inside of cheeks while eating;
-Allergic reaction to certain foods;
-Vitamin deficiency (most often lack of the vitamins B1, B2, B6, zinc, calcium, iron.
-Stress and anxiety;
-Diseases such as celiac disease, Behcets disease and Crohns disease, Reiter syndrome, syphilis and others;
-Side effect of drug use (be careful when you buy different kinds of medicines, especially for children);
-Toothpaste (toothpastes containing sodium sulfate often cause mouth blisters) and products for freshening the breath usually dry the lining and make it susceptible to infections that can be followed by an outbreak of mouth blisters;
-Poor hygiene of the mouth.

It is very easy to prevent the occurrence of mouth blisters. You just need to avoid sharp, crispy and coarse foods which sore the mouth tissues and lead to the occurrence of mouth blisters. Do not also eat often acidic, spicy and salty foods, especially when you already have blisters. Avoid also spices, coffee, cigarettes and chewing gums. You should maintain good oral hygiene as you brush your teeth regularly. Your toothbrush should be changed at least every 3 months and it should be soft (if your mouth tissues are very sensitive). Choose appropriate toothpaste that does not contain sodium sulfate and does not irritate the mouth tissues. You can rinse your mouth with chamomile and sumac. The use of hydrogen peroxide when you have blisters is also a good idea, but it is not recommended for young children. Lactobacillus acidophilus (probiotics) prevents the recurrence of blisters in the mouth.
