If the second worm gear is destroyed then odds are the first worm and magnet bushing is toast as is the first worm drive gear. When the bushing goes bad the first worm and magnet gets tweaked off alignment from the second worm and thus the eating starts.
If you replace the second worm and the teeth on the first worm are bad, it will usually just eat the new gear, up especially if you use the plastic replacement second worm gear. Considering how hard it is to remove the speedo from the car it seems only sensible to repair the head if the second worm is out on it.
