If a veneer is rebounded , is there a chance it will just come loss again?

There is always the chance that a veneer can come off, but certain factors can make that highly unlikely.  If the prep is cut well by an experienced dentist, the veneer is of great quality, the proper cement is used, and the bite is properly aligned, then your particular veneer should last another 8 years.  Good luck and I hope this helps.

The first issue is to find out WHY it came out, as often it is not a cement failure issue as much as a bite issue.  If all other issues are "within normal limits" then the primary concern is to bond the veneer.  However, NOW it is not the same as the day it was first put in.  Similar to removing a bumper sticker from a car or a notebook cover, some of the glue remains on the bumper or book, and the sticker often has dirt stuck to it.  Despite all efforts to clean and prepare the surfaces, it is never going to be the same as the day it was first placed.If the veneer comes out again, a complete remake will be best.  If the tooth is hurting, it may need other treatments first.

It is possible that the veneer could come loose again. If you feel that it is loose I suggest revisiting the dentist and letting them determine if it is loose. Many times veneers come loose for a reason other than cement failure so it needs to be determined why the veneer came loose to begin with.

if it came loose again, you should consider a crown of zirconium, because one of the things that make veneers come loose is the margins, if they are not perfect, the glue starts to decay, and then they fall down, so provably this is why you should check this, and provably a crown will work better for you.
