That's up to you. We have treated wounds just as bad ourselves with no problems. It's amazing how fast and how well snakes(living creatures in general) can heal. The real factor is keeping it clean and infection free. If you can do that, then I am willing to bet it will heal just fine. Do like others have already told you and you should be fine.
You can skip feeding it for a few weeks to be on the safe side. I bet it will be healed up pretty good within a couple of weeks.
