Hello, I hope that I can help answer your question. I think you are correct in your assumption that you damaged a nerve. The branches of the fifth and seventh cranial nerves supply the face. These nerves can be damaged either directly (as in you crushed the nerve during the accident), or they can be compressed by swelling of the tissues of the face.

Either way, the feeling will probably come back. Any Nerve, outside of brain/spinal cord, can regenerate, but it often does so quite slowly. For example, for nerves above the shoulders, they grow about 1/5-1/2 mm per day.

As the sensation returns to your face, you should experience so increased tingling in the areas that may be quite annoying. But don't worry, this is part of the healing process.
