If you're one of the many people out there who are terrified of going to the dentist, this article is probably going to do very little to alleviate those fears. Sorry.
And it turns out that yes, yes they can.
In a video to his account, he explained: "I get this question a lot, and yeah, we know."
In a second video, he then elaborates on exactly how this is possible.
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."
Then, sharing a photo of what it looks like IRL, he says: "As you can see, bruising of the soft palate and irritation right there."
Clearly panicked by what they had just been told, thousands of viewers shared their concerns with the good doctor.
Commenting on the video, one person joked: "My grandpa is a dentist. I will no longer be needing teeth."
Another said: "Okay, so I've worried that they could somehow tell and I've always thought it was an irrational fear, soo thank you for ruining that for me."
While a third put: "Oh my goodness. Does it heal? Asking for myself."
Several other dentists have also chimed in with their expertise. Just in case you don't believe him.
Responding to questions from people on social media, TikTok dentist @thyrants said: "Yeah, sometimes we can tell.
"And it's usually bruising on the soft palate called petechiae. But unless the patient's really young or shows signs of abuse, we don't care."
But if you're worried about a dentist being able to tell your whole sexual history just by looking inside your mouth, fear not.
Another TikTok user, a dental hygienist called @mandimaeee, said: "So a friend of mine sent me this video and was like, 'Oh my god, Is this true?' Yes, it is.
"To say that I'd be able to tell if you did it three years ago? No, but if you did it recently and you were a little bit aggressive about it... Some individuals might have, um, bruising to the palate, if you know what I'm saying. Soooo yes, we can tell."
