If there is no apparent infection, continuing to apply the ointment will simply mascerate the skin, making it worse instead of better. What you want to happen is for the exposed nail bed to 'dry out'. You might try applying a drop of alcohol to the area to dry it out. If it burns too much, then simply allow it to be exposed to the air. Do not use a bandaid or any type of tape to wrap it with. You can wrap the toes with gauze and use part of the gauze to tie it to your foot/toes if you are in an area where it could become exposed to bacteria. You can also use a bacterial spray that will not mascerate the wound if you are concerned about infection.

I don't think you will be wearing any type of shoe by January, much less weating dancing shoes. If you are wearing closed-toe shoes now, you might want to consider weating an open toe sandal with a pair of white cotton socks on that foot.
