Hi everybody, i need a hand!
i have a project with some meshes that rapresent tooth and gum (see the attached image).
 
I wrote a program for tooth handling (the white meshes) and i use it to move/rotate every tooth.
When i move a tooth the gum moves itself to reconnect the tooth but moving itseft it creates some holes near the adjacent tooth.
Somebody can tell me how I can  do to refill the hole?

thanks!
