A dentist has gone viral after revealing that he can tell if a patient has had oral sex by checking their mouth cavity.
The professional shared it on his TikTok account @dentite in a duet video, and admitted that he and his colleagues can definitely tell.
In the clip, he further explains that there's a condition known as palatal petechia – round bruising-like spots around the palate.
He says: "Palatal petechia. This is what it's called.
"If you like, say, sucking on a lollipop, one or two, here or there, not a big deal.
"But let's say you like sucking on multiple, multiple, multiple, multiple lollipops all the time, you've got a problem that's gonna cause palatal petechia."
Viewers commented that they got worried after learning the truth.
