How do you get rid of canker sore in the mouth?

Unless they are hindering movement or are extremely painful due to their size and/or location, blisters should not be ruptured, or "popped," as doing so can introduce bacteria into the wound. If a blister does burst, the extra skin should be left intact. Blisters that are excessively large or painful should only be punctured using antiseptic procedures, preferably by or under the direction of a qualified health care professional.

Treatment of blisters depends on their cause. Blisters that are symptomatic of a disease or disorder require treatment of the illness itself. Blisters caused by friction or trauma can be treated by cleansing with mild soap, applying an antiseptic, and covering the area with a sterile bandage. An herbalist, aromatherapist, or holistic health care professional may recommend a compress of an antiseptic or antimicrobial herb such as marigold , thyme, lavender, or tea tree oil.

The blister should be kept clean and the bandage changed frequently. Blood blisters should be bandaged firmly to apply pressure to the area and prevent further blood vessel ruptures.

P.S. don't type or listen to How do you cure blisters? because is just says bend down and suck it, not very helpful

Or, you can burn a needle (this is to kill any bacteria that might be on it). Next, thread the needle (optional) pop the blister with the needle and pull it through so that only the thread is in the blister. this releases all the plasma and air inside the blister. apply neosporin and pressure to the blister. sleep with the thread in the blister and pull it out in the morning. apply more neosporin and a band-aid.

This method works very well. I get blisters every day from my pointe shoes and i used to do this after every class but i don't have to anymore because i have calluses
