I thought I had mastered my temporary speech impediment after a week of tray one but when I moved onto tray two, I had a whole new set of problems! Other "s" words started causing me problems and I suddenly struggled with B's and P's. It has gotten better throughout this week. I am hoping tray three doesn't bring new issues. 

I have noticed a pattern with my first two trays:

- Day 1: tightness and pressure with the trays in

- Day 2: trays feel better, but teeth hurt while eating, especially biting

- Day 3: teeth still hurt a bit while eating, every so often the trays feel tight

- Day 4: trays are barely noticeable, still some tenderness while eating

- Days 5-7: all good

Things are still way better than I remember traditional braces.
