I’ve been doing the invisible braces thing since i was 12-14? Can’t remember. Mom took care of that. After been done with the alignment process, doc gave me up and down retainers to wear every night. Fast forward 4 years after treatment (I’m now 21yrs old), I needed to get a second pair to replace the old ones because of significant cracks.

2 months in wearing the new ones (fit was weird the first week), I start to notice that my center tooth gap is showing again? Is that a thing? It ha started getting really tiring wearing these crap, which nobody asked me about the first time.
