Day one. Tray one. I previously had braces from 7th grade to 9th grade. I wore my retainers for about a week b4 losing the top one. I got it replaced for $150 and lost it again and was too guilty to tell my mother. Since then my teeth went into a gradual relapse which has bothered me psychologically all through college but now I actually have the funds to try out Invisalign.
Anyways the trays popped right in and I'm glad my tongue isn't strong enough to pop them back out. There is a slight discomfort and my speech is affected only slightly, not enough to get self-concious. I also want to add that the top tray acts as a really nice tongue scratcher (only other patients would probably know what I am talking about). Sooo let's begin the journey!
