Fever Blisters cannot fully heal until the pus-like fluid is extracted from the blister. The toothpaste salt remedy will drain all fluid from the fever blister in one day, producing only a tiny scab. Be patient and allow the scab to properly heal.

To help speed a fever blister's healing time apply ice. Wrap 1 individual ice cube in a paper towel and place onto fever blister. Ice can slow a fever blister’s development and numb the skin surrounding the blister for instant pain relief. Apply ice every hour for 10 to 15 minutes daily until fever blister heals.


Consult your physician immediately if fever blisters worsen, cause your face to swell or do not heal within two weeks. While fever blisters are very common and affect nearly 75 percent of the world's population, they can be a symptom of a serious medical condition. Refrain from using salty toothpaste remedy if your skin is very sensitive.
