A concussion is not bad as a lot of people make it out to be. Many athletes suffer numerous concussions throughout their career and that’s not safe. However, many regular people suffer from multiple concussions throughout their life and see no adverse effects (personally I’ve had 2).

As far as the face-planting goes he may have a few minor scars, because from what you described doesn’t seem as bad as some of the **** I’ve seen but no real malformation.

And the tooth, dental implant, bridge or crown to fix that.

Hope he gets better soon though.
