Kelly Clarkson 'gets emergency root canal'

Kelly Clarkson has undergone an emergency root canal for an infected tooth.

Posting on her official Facebook page, the 'Since U Been Gone' singer shared photos of herself at the dentist's office where she had the procedure done.

"Emergency root canal... I've had better days," she wrote.

"I just got finished at the dentist and I can't feel [a] portion of my face... It feels so weird and I keep thinking I'm drooling on myself which is so incredibly attractive, I'm aware. Oral surgery = sadness."

Clarkson recently completed work on her fifth album.
