In Spencer's case, the fact that there was no blood when the tooth fell out suggests blood flow was obstructed, which may have caused his tooth to deteriorate, Li said. While rarely used to investigate chemical senses disorders, imaging studies could show pathological findings in several patients with STD. Moreover, the findings point to the possibility that the mouth plays a role in transmitting SARS-CoV-2 to the lungs or digestive system via saliva laden with virus from infected oral cells. According to the CDC, to prevent infection and the transmission of SARS-CoV-2, a person should consider: The CDC recommends that people who are not fully vaccinated wear cloth face masks in indoor public settings.

Rashes and skin changes have been frequently reported since the pandemic's early days, and those can extend to the tongue.
