Morphology
loose-toothed + smile
The noun is a transparent adjective–noun composition: 'loose-toothed' can be parsed as 'loose' + 'toothed' (having loose teeth) and combined with 'smile' yields a smile that shows loose teeth. This is fully compositional and follows normal English compounding patterns (and similar logic exists in many languages), so a B1 learner who knows the constituent words can derive the meaning.
Etymology
Loose-toothed smile is a picture of someone, often a child, smiling with a wobbly tooth or a gap where a tooth will fall out; the words loose and toothed make that image clear. That's why it means a smile that shows teeth not firmly in place and often feels 'proud' or 'charming'.
