Jessica Alba lost a tooth while shooting sex scenes for her new movie - because the romp was so violent.

The 'Sin City' actress is starring in romantic comedy 'Good Luck Chuck' with Dane Cook and admits the frantic scenes left her nursing a sore mouth.

Alba told TV show Extra: "We shot all our love scenes in one day and I actually lost a tooth. I chipped a tooth as well so I need to get that fixed. Isn't that disgusting?
