Remember back in the day when kids with braces were called "metal mouth"? Times they are a-changin'! Nowadays, dental work doesn't have to cramp your style.

Just look at Teen Mom 2 cutie Kailyn Lowry, who got braces just before Christmas. But these aren't just any braces — they're invisible!

According to Kailyn, she's sporting Damon Braces, a special kind of mouthwear made of clear or translucent parts. They're hardly noticeable in this adorable selfie Kail recently shared on Instagram.

We can't wait to see the reality star's pearly whites when the braces come off — hopefully just in time for her wedding with Air Force cutie Javi Marroquin!

What do you think of Kailyn's new (and soon to be improved) smile? Tell us below!
