Thalia before
When the legendary pop artist first hit the scene in the 1980's she was in the popular band Timbiriche. This photo taken in 1989 shows her beautiful smile, which was all natural back then. She just didn't like to show it too much.

Gloria Trevi before
During an interview in the 1980's, the Mexican pop star was seen modeling her natural teeth. She had some gapping, but that's nothing braces can't fix.
Gloria Trevi after
La Trevi has been around for decades. Of course she has gotten work done to stay youthful, but I wish she would have left her teeth alone or gotten a different type of treatment.

The former Jersey Shore star had super white teeth when she first started, but they were definitely misaligned. She made sure to get that fixed!
