A Dallas-area woman has gone viral on TikTok after accusing a dental office of attempting to scam her by claiming she had multiple cavities that she says did not exist.
Madison Sieli, who posts on TikTok as @madisonsieli, said she booked an appointment after the office contacted her offering a free cleaning and teeth whitening. She said she researched the practice beforehand and found positive reviews, making the offer seem legitimate.
“I needed to go to the dentist anyway,” Madison said in her video. “I looked them up, and they had good reviews.”
According to Madison, the appointment initially appeared routine. Staff took X-rays and scans, and she was asked to sign a consent form allowing some images to be used on social media. Madison said she regularly maintains her dental health and had seen her longtime family dentist within the previous six months without any problems.
She said the visit took an unexpected turn when the dentist reviewed the results.
“She said, ‘Unfortunately, you do have seven cavities. Two of them are pretty bad,’” Madison recalled. The dentist allegedly recommended a root canal and encouraged her to move quickly on treatment.
The diagnosis raised immediate concerns for Madison, who said she had never had cavities and could not understand how several severe ones could develop in such a short time. She also said she was put off by questions about her diet and oral hygiene.
“I don’t eat candy every single day,” she said she told the dentist.
Madison said her suspicions deepened after speaking with a friend who described a nearly identical experience at a different dental office. That friend reportedly sought a second opinion and was told no treatment was needed. Madison then visited her family dentist, who she said confirmed that her teeth were healthy.
“Pretty fuming at this point,” Madison said.
She later contacted the original office to voice her concerns, accusing the practice of misleading patients.
“You guys are scamming people, and that’s not OK,” she said she told staff.
Madison ended her video by urging viewers to advocate for themselves and seek second opinions when diagnoses seem questionable. As of Wednesday, the video had been viewed more than 431,000 times.
Dental experts note that while intentional fraud is not common, disagreements in diagnoses can occur. Some dentists may recommend early intervention for minor issues, while others prefer a watch-and-wait approach. These differences in clinical judgment can sometimes appear suspicious to patients, especially when costly procedures are suggested.
Commenters on Madison’s video shared similar stories, with several claiming they were told they needed expensive dental work that later proved unnecessary. Others criticized corporate dental chains, arguing that production-based business models can pressure providers to recommend more procedures.
