A woman, with 1.7 million followers on TikTok, has scored a Guinness World Record for her gigantic mouth.

Samantha Ramsdell, from Connecticut in the US, broke the record for the world's largest mouth gape of a female measuring in at 6.5cm.

The 31-year-old has gone viral on TikTok for the unusual party tricks she can perform with her mouth, but admitted she used to be an extremely insecure about the body part.

The medical sales representative told Guinness officials that she feels "great" that her mouth is now a reason for celebration.

Growing up, she was often bullied with other kids calling her hurtful things like "big bass mouth" among other names, but she now describes her mouth as her "superpower".

"You know getting a Guinness World Records title, it's finally being almost able to show some of the bullies or people who doubted me, or tormented me, that hey – I have a big mouth but at least I have the biggest one in the world," she said.

"Being 31 and being able to get a record for something that really I was so insecure about, something that I wanted to keep so small, it's great because now it's like one of the biggest, best things about me."

Guinness World Records also compared everyday objects to her enormous gape, uncovering a range of party tricks she can perform with her mouth.

These include nearly fitting an entire green apple in her mouth, fully biting through four-single stacked cheeseburgers and stuffing an entire large size chips in her mouth.

Looking for a creative outlet, she joined TikTok last year during the pandemic even though at first she felt "too old".

"But it was the one thing I could do right now to keep me busy and keep me creative, so I started doing some singing, some of my comedy stuff, and I did one comedy video where I made this crazy face, and the children of TikTok were like, 'what happened to your face?!' " she told Guinness World Records.

She had just 300 followers when she initially started out, but the unique things she can do with her mouth have gained her millions of fans.

"My mouth has set me apart from the other millions of comedians, singers and all these other creators. I never thought it would be possible to be this famous off my mouth, but it's incredible. It's really cool," she said.

While Ramsdell must be every dentist's dream, she has previously revealed that she lost 22kg two years ago, which helped her regain a bunch of confidence.

Her own dream is to one day to have her own show and including humour, wit and singing as part of her routine.
