This may sound crazy.. But if you have a swollen taste bud just take a sterilized nail clipper and clip it off. I know is sounds painful but it works. You can sterilize the nail clipper with rubbing alcohol. FYI, it would be best to use the smallest nail clipper you can find like and infant's nail clipper. Try to keep your mouth clean with "Glycerin" which you can find in any health food store. Just wrap a cotton ball on the tip of your finger and saturate the cotton ball with glycerin then clean all around your mouth (gums, teeth, tongue and cud-which is the walls of your mouth).
