Cold Dressing
In order to get rid of the appearance of sores quickly, try applying a cool, damp cloth to external blisters. In this way, the redness and scabs will be less and they will heal faster. If you notice that mouth fever is about to appear, but is not yet visible, it is recommended that you apply ice to the affected area. This method can reduce the size of the sore. When it eventually happens, it can heal more quickly. On the other hand, if the sore is kept hydrated by licking the ice, it can prevent the sore from drying out, causing it to crack, and leading to secondary infection.
