Cathy Blythe, 33, had a gastric bypass in 2011 and went on to lose a lot of weight - although that's not all that she lost.
Despite taking supplements daily, she has since suffered various problems, saying she's noticed herself becoming anaemic and has had low vitamin levels, which have wreaked havoc on her teeth.
Cathy, from Michigan, US, said: "Before my bypass, my natural teeth were perfect and healthy.
"Until I was 24, I had never even had a cavity. But a few years after the bypass my teeth became fragile and weak.
"I had lots of cavities and my teeth were breaking off.
"Over the last eight years I have spent a lot of money trying to save my teeth."
Cathy, who runs her own business selling crystals and minerals, had numerous fillings, crowns and root canal treatments but said nothing could save her teeth.
She added: "I could have spent thousands more dollars but nothing was guaranteed that I wouldn't need dentures soon anyway."
In December 2020, Cathy decided to have her remaining broken teeth removed and replaced with a full set of dentures, having discovered a TikToker who had done the same.
After receiving the dentures in January, she now hopes to get implants fitted within the next few years.
In the meantime, she's been sharing her story on TikTok to help others who may be in a similar situation, having recently gone viral for sharing a video of herself in her parked car, waggling her teeth at passers-by.
In the clip, which was been viewed more than 2.9 million times so far and racked up 830,000 likes, she pops out her bottom dentures with her tongue, before shaking them and waiting for someone to notice.
Cathy believes her light-hearted videos about dentures helps reduce the stigma around young people wearing them.
She said she often receives comments from people asking why she needs dentures, and that many assume it's due to drugs or poor dental hygiene.
Cathy continued: "I want to help people realise that people of all ages have dentures for all different reasons.
"When I had my gastric bypass surgery they weren't recognising that the surgery could have very negative effects on your dental health, even if you are doing everything right, but they now are and have done some research and studies on the matter.
"Before someone gets the surgery, I believe they should be warned about what could happen - I constantly have people tell me the same thing happened to their teeth."
