• Amos Dudley wears his skills in his smile.

• The digital design major has been straightening his top teeth for the past 16 weeks using clear braces he made himself. 
• "I'm still wearing the last one," Dudley told CNN on Monday 
• "The last one" refers to the twelfth and final straightening tray in his self-designed treatment.

• Dudley said he had braces when he was in junior high, but he didn't wear his retainer as much as he should have, and his teeth shifted.
• Over time, Dudley discovered that he wasn't smiling as much because he wasn't happy with the way his teeth looked.
