I had my first broken toe this February after almost 23 years of training. Big toe on the left foot due to sparring during a seminar. (I wasn't wearing pads and my opponent blocked my kick with his elbow - ouch!)
Anyway, keep it taped to the toe next to it and do not over do it when training or teaching. I was making good progress after almost 3 weeks and decided I could do more kicking. That was a mistake as the pivoting during kicks was OK at first but then got really painful. After that it took probably another 3 weeks to feel nearly 100%, again.
Best advice is to keep it taped and take your time. Make sure you're completely pain free before starting back with kicking.
Pax,
