AE1007 Outer Cover to Double Deck Zipper - Teeth broken out

[claridgesnz]

I managed to misalign/jam the Outer Cover to Double Deck Zipper behind the rear paddler on my AE1007. In the process of brute force removal, two teeth were broken out on the outer and one from the deck. I'm in New Zealand South Island, out of warranty and not keen to pay for a restitch with a new 4m zip all round if it can be helped. I've seen YouTube evidence of what amounts to "dentistry implants" of cannibalised matching zip teeth re-glued into place... Has anyone tried this technique? https://www.youtube.com/watch?v=X73uAKHFCgQ
Or any other suggestions?
