Make a final check to ensure that the zipper slider moves smoothly over the replacement teeth:

Tooth is Loose: Tooth isn't firmly adhered to zipper tape and wiggles when touched.

Not Enough Pressure: Tooth sits firmly and doesn't wiggle, but the tooth is too thick so the slider doesn't glide smoothly over replacement teeth.

In both cases, reapply the rig and apply firm pressure until the tooth doesn't wiggle and the slider moves smoothly over it.

If available, use a set of calipers to ensure that the height of the replacement tooth is the same as the existing teeth.
