In the books, there are two opposite ideas outlined:

1. Soul retained, if sb dies ("taking a train" to afterlife or becoming a ghost)
2. Soul (fragment) destroyed, if the horcrux holding it is destroyed (opposite to living container)

Unfortunately, Rowling makes a contradiction:

Ron: "Isn't there any way of putting yourself back together?"

 

Hermione: "Yes, but it would be excruciatingly painful."

 

Harry: "Why? How do you do it?"

 

Hermione: "Remorse. You've got to really feel what you've done. There’s a footnote. Apparently the pain of it can destroy you. I can’t see Voldemort attempting it somehow, can you?"

And Harry to Voldemort:

try... be a man... try for some remorse. It's your one chance. It's all you've got left.

How on earth can Voldemort's soul be put back together, if all his horcruxes are destroyed, thus also the soul fragments in it?

The only plausible explanation is that the pieces aren't lost forever, they are just hiding somewhere in an 'outer void' out of Voldemort's reach, until he shows remorse.

Lupin about dementor's kiss:

You can exist without your soul, you know, as long as your brain and heart are still working. But you'll have no sense of self anymore, no memory, no...anything. There's no chance at all of recovery. You'll just — exist. As an empty shell. And your soul is gone forever... lost.

So, I think if dementor sucks a soul out from a person (or a living/not-living horcrux I think, if it would want to, cause its still holding a piece of soul), it goes to a similar 'outer void'. If it is the same 'void', then Voldemort could still repair his soul, after dementor has sucked all the fragments out of the 7 horcruxes, by showing remorse. But if it is another 'void', then the fragment really is 'lost forever'.

What I would have done if I were Dumbledore, is that when I find a horcrux, then let a dementor suck the soul fragment out, thus the item itself is retained (don't have to physically destroy it). Of course I wouldn't trust it to do it on Harry, cause what's an angry severed soul next to a happy whole one.

If the kiss would be performed on Voldemort, then it could be even better fate for him that he finally experienced: we don't know if his soul fragment would suffer in that 'void' [but probably would, because a soul fragment without body always seems to experience pain - be that when floating around in Albanian forest, or eternally suffering in King's Cross limbo; the pain is reduced when it finds a host - mouses were bad; snakes better, because he understands them; Quirell even more better, but still weak (had to drink unicorn blood); and painless when in its own body]*
