Well if its just a hole, then your body will heal it. Put some anti-bacterial ointment on it and you'll probably be fine.
The bite just killed some flesh, body got rid of it, now you have a hole that your body needs to heal. Just keep it clean and covered with some Anti-bacterial cream. If it starts to get red and puffy and painful, or the tissue starts to darken, go see a doctor for anti-biotics.
Edit: just how big a hole are we talking though ?
