I had braces from late 2009 - mid 2011 (mid-Freshman year to the summer before Junior year of high school). I really hated having them in my mouth. I had trouble speaking with them & I was uncomfortable with my smile during this time.
It was worst while I has the guard & the rubber bands. AT THE SAME TIME.

Then I got them taken off during the summer, & I could not speak or smile with the retainer so I couldn't stand wearing it in school.
It feels so amazing to not wear any contraptions in my mouth during the day now. I still wear my retainer every night even though it's been a year & a half.
