After falling off a bike as a child when she was knocked by a car, she was left with “black teeth” after the nerves died.
Because of this, she was the victim of cruel bullies who taunted the Newcastle-native for her unique smile.
But today the TV presenter finally got her own back on the bullies, as she confidently showed off her pearly whites in the form of a new set of crowns.
Taking to her Instagram to share the happy news, Scarlett could barely contain her emotions as she told her 1.5m followers about the procedure and how happy she now was after years of hiding her grin.
She captioned the video: “First time in 16 years I can confidently smile, thank you so much to Dr Ilaty at @thewelbeckclinic for changing my life. For calming me when I felt anxious as I hate the dentist & for making me want to smile again.”
Wearing a red jumper and dramatic red, tassled earrings, the 27-year-old admitted this was her “11th” attempt at making the video, after being unable to hold back her tears of happiness during previous recordings.
She said: “So as you can see I’ve been crying and this is the 11th time I’ve done this video so hopefully this one i don’t start crying.
“Some of you may know that when I was 11 I was in an accident and I lost my two front teeth and the nerves in my right tooth were black for pretty much all my teenage years until I was about 21.
“I’ve never felt confident to smile, even when I got my crowns when I was 21 for my birthday, I still put my hand over my mouth.
“Thanks so much to Dr Illaty because for the first time in 16 years I can smile and be confident. I’m going to be grinning like a Cheshire cat everywhere.”
And her fans were more than supportive of the I’m A Celeb winner.
One said: “You look amazing! I just read that chapter of your book last night and could feel myself welling up. You are beautiful x.”
Another added: “They look beautiful I could only dream of having a smile that good.”
One wise follower weighed in, saying: “You look gorgeous, but more important it’s made you smile and your confident and happy, that’s more important than what other people think about you.”
Her amazing new look comes not even two weeks after the star announced her split from Luke Crodden – who broke up with her on her birthday.
Scarlett took to Facebook to confirm her 18-month relationship was over, telling friends that it was “Luke’s choice in the end” after the spark died out.
The couple first split back in February following a year-long relationship and then rekindled their romance in June.
