Lumineers and gum recession, do I lose all the money I invested in lumineers?

Hi There, I was about to start the Lumineers treatment next week but my family dentist told me that with my normal gum recession I might have to redo the lumineers all over again because the gum recession will expose part of my teeth and there will be a gap between the lumineer caoting and the new exposed tooth where food can get stuck. Is that true? If that happens, will I need to pay for the whole process again?
