I think the diagnosis of a missing tooth from 1st gear is probably correct. In my experience this is usually connected with attempts to free a stuck clutch. As someone has already noted, 1st gear is part of the kickstarter mechanism.
Unfortunately you either live with it and hope the broken tooth stays out of the way, or its a total engine strip.
