One more question for the knowledgeable people at smd:
my wife's maxillary incisors each have 4 or 5 lines running vertically
on the labial side. Her dentist only recently noticed this (there
should be an age limit associated with performing dentistry..but I
digress) and asked whether she tends to suck on lemons, which is not
the case. Any other ideas what these lines or ridges might be ?

Most likely small hairline cracks in the enamel. Most of the time
these never go anywhere. Lemons? Doubt it.

Lemons and limes cause horizontal troughs in anterior teeth.
Vertical 'craze' lines are usually from parafunction.
