Can my Teeth Still Shift/grow with Retainers?

I have had my retainers for 3-4 years now (wearing them always at night). Although they fit, I noticed that there's a small space between a few of my teeth and the retainer (specifically the canine and the teeth directly under it). I have talked to my ortho about it however it is not the same one who has treated me through my braces process and he claims there's nothing wrong. However I feel like my teeth grown throughout the years and may be the reason why my retainer doesnt fit like it oncehas

Teeth CAN move

Retainers aren't bulletproof and can warp.  Night time use is not as effective as 24/7, so expect SOME shift, but VERY little.  If "perfect" is a goal, get used to disappointment.
