Margot Robbie is still wearing her retainers

The 27-year-old actress was told by her dental practitioner when she was 14 that she would need to keep the plastic guards in for two years, but she has continued wearing both the bottom one, for teeth grinding, and top one for movement for 10 years. Appearing on Australia’s ‘The Kyle and Jackie O Show’, the blonde beauty confessed when asked how she coped playing a character with a lisp in ‘Peter Rabbit’: “This is so embarrassing, I actually have two retainers, one for the bottom teeth which is for grinding and one for my top teeth which is just so my teeth don’t move. “The orthodontist, when I got my braces off when I was 14, said, ‘You’ll need to wear it for two years but I am so paranoid that, 10 years later, I’m still wearing them.” The ‘Suicide Squad’ star revealed she took extreme measures to try and stop her teeth grinding habit by having Botox injected into her muscles inside her mouth. She said: “I grind my teeth so bad I ended up getting Botox in the muscles there and it stops you from grinding your teeth.” Margot portrays Flopsy the bunny - who suffers from speech problems in the big screen adaptation of the Beatrix Potter classic. ‘Peter Rabbit’ stars James Corden as the voice of the mischievous bunny created by British children’s author Beatrix Potter and published in the early 1900s. Meanwhile, Margot is reportedly in talks to star in the Quentin Tarantino-directed ‘Once Upon a Time in Hollywood’.
