Blister In My Mouth Is It Safe To Put Rubbing Alcohol On A Blister In My Mouth?

Is it safe to put rubbing alcohol on a blister in my mouth? - blister in my mouth

I chewed gum a few days ago and is very painful. I have not improved a white bubble on the inside of the mouth. Warm salt stunned only for so long. I began to put alcohol on them to kill germs. Is it safe? Other ways to get rid of this painful blister fast?
