You should continue wearing a mouth guard indefinitely.  You should wear a mouth guard even during a short nap.  If you end up grinding down your mouth guard then buy a new mouth guard ASAP.  It's better to grind down your mouth guard than your own teeth.

Teeth grinding could be a side effect of excessive caffeine intake or from taking anti-depressants.

I would see a TMJ specialist about the teeth grinding.

You should talk to your general dentist about the gap in your teeth.
