The OC actress Mischa Barton blames a surgery on her wisdom teeth for her admission into Cedars-Sinai Medical Center psychiatric ward in July.

"I was overwhelmed," People magazine quoted her as saying.

"I had too much work going on. I had a surgery for my wisdom teeth that went really badly. I had four (wisdom teeth) taken out and they had gotten it really wrong. They had to drill into my jaw and I was in excruciating pain." Barton now insists that all is well, and that she has been doing everything to keep her job and health in perfect working order.
