This may be a bit wild but use pll and trigger when the expected pulse
doesn't appear. Maybe a bit far out of the box.
Basically the reverse of synchronous detection.

I have a optical encoder from a mouse running on an emco encoder wheel
(100 holes). I cut out the metal between 2 holes. I think that would be
considered one missing tooth... I have the encoder scale set to 100 and
the missing tooth set to 1
I have a little comp that sets the index enable to true whenever it is
false.
Looking at the halscope screen shot - it only counts to 98.. I would
think it would count from 0 to 99. You can see the gap is seen - but I
think there should be an extra count in there..
(I could be not understanding it too)
ps - if I set the missing teeth to 2 - it will not trigger (like it
doesn't see the gap then which seems correct)
thanks!
