Can washing powder really whiten teeth?

At first, many people regarded washing powder as a cleaning agent, and used it for everything. Isn't this the case below? When they saw washing powder to whiten their teeth, they mistrusted the use of washing powder, and they showed abdominal pain and diarrhea caused by washing powder. Guiyang Evening News reported that on the evening of June 5, a 14-year-old girl from Guiyang, Xiaomei, mistakenly believed the information on the Internet that brushing her teeth with washing powder can whiten her teeth; she sprinkled washing powder on the toothpaste when brushing her teeth, and she suffered from abdominal pain and diarrhea. According to Xiaomei, she was in the second year of junior high this year. On the evening of June 5, she saw an article on the Internet; washing powder may whiten teeth; the post said that brushing teeth with toothpaste followed by washing powder had unexpected whitening consequences... After reading the post, Xiaomei followed the above statement that night, sprinkled the washing powder on the toothpaste and brushed her teeth for nearly ten minutes. As soon as she brushed her teeth, Xiaomei felt a burning sensation in her mouth. More than an hour later, Xiaomei had abdominal pain and persistent diarrhea. She was then received by the Provincial 96999 Emergency Relief Center for medical treatment. After treatment, there was no serious problem. The doctor suggested that the claim that washing powder will whiten teeth has no scientific basis. When washing powder enters the body, it will destroy the red blood cells in the blood circulation, causing diarrhea, and even atrophy and cirrhosis of the liver in severe cases.
