The "Tasnim" news agency quoted Farshid Bastami, technical deputy and supervision of the medical system in Greater Tehran, as the one who reported that an "unlicensed" beauty center in Tehran, which had extensive advertisements on Instagram, intentionally destroyed the teeth of a 25-year-old girl who only came for teeth whitening with phosphonic acid. Bastami said about the details of this case: "After the work is done, the patient is faced with chalk-colored and very distorted teeth. "Expert investigations found that the staff at this center intentionally used phosphoric acid instead of standard bleaching agents." According to him, in response to this patient's protest, the agents of this center told him that "you don't have a whitening agent" 10 times the cost. Criticizing the entry of investors who are not doctors into the health field, the deputy supervisor of the medical system in Tehran warned: "In such centers, the patient's healthy teeth are destroyed with acid to force him to undergo much more expensive and invasive treatments such as composite materials."
