SeaWorld Orlando's trainers will stand farther away from the killer whale who drowned a trainer at the park last month when brushing his teeth.

Now trainers will have a 2-foot extension to brush Tilikum's teeth three times a day.

Forty-year-old Dawn Brancheau was killed after being thrashed underwater by the whale after a performance.

After the Feb. 24 death, SeaWorld removed Tilikum from its daily shows and ordered its trainers to keep their distance from the animal. He is twice as big as any other orca at the park. The park imposed the restrictions while it reviews its killer whale safety protocols, which is now expected to extend into April.

Tilikum continues to live in the park's seven-tank orca complex and learns new behaviors now that trainers don't get close to him.
