If you do end up getting it removed, I wouldn't even worry about how good your toes are looking! I lost my big toe nail after a season of soccer a couple of years ago and was so self-conscious about the way it looked at first. Just leave it, paint the other toes, and let that nail grown back healthily! It will grow back to be a fresh, strong, perfect nail.
My recommendation, though, is to purchase Tea Tree Oil and apply a few drops onto the skin (where the nail is missing) every day. Even when the nail starts growing back, apply the Tea Tree Oil. This really helped my nail grow back (faster, I think?) healthy. I did find the skin would get very dry and peel, but it is only because it is skin that has never really been fully exposed. Just keep it clean, healthy and do not even worry about that this toe looks like until it has grown back! I wouldn't even bother with a fake nail or covering it with polish - I feel like either of the two would inhibit the nail from growing back its healthiest!
