Brazilian star Ronaldinho has reportedly undergone an operation to have his teeth straightened.

Reports in his native country have claimed that the two-time FIFA world player of the year had a procedure inserting porcelain veneers.

"It's part of his normal [dental] treatment and won't affect him at all," Ronaldinho's brother and agent Roberto Assis told O Globo.

The surgery, which is said to have involved work on the Atletico Mineiro player's gums, lasted just under one hour.
