I do not believe LVT's should be permitted to close gingival flaps associated with oral surgery and extractions.  These can be some of the most challenging surgical sites to close properly,  Suture selection, making sure that underlying bone has been smoothed properly to prevent sharp edges that may disrupt healing and ensuring that there is not too much tension on closure, all affect healing and successful outcome.  Many times size and degree of gingival and palatal elevation needs to be adjusted and tweaked during closure in order to maximize healing.  These are decisons that should be made by a veterinarian.
