12 yrs ago, I broke off 80% of both top front teeth in an accident (needed crowns & root canals). I want to replace them (gums receded & they look old), but I'm afraid that replacing them too often will weaken what's left of the underlying tooth structure. Is this a valid concern? Should I wait?

Upgrading crowns can be done safely
While your concern IS valid, if an experienced cosmetic dentist does the treatment the risk is low. Quite often it is not necessary to remove the entire crown and can be veneered. Depending on how much tooth structure was removed initially, it is likely that replacement will be uneventful.
