Dentist reveals telltale sign that shows how much oral sex you have

When it comes to what goes on between the sheets, most of us prefer to keep our cards close to our chest.

Apparently, however, there's one group of medical professional that claim they're well aware of all of our dirty little secrets - especially when it comes to oral sex.

We are, of course, talking about dentists, hygienists and orthodontists.

Speaking to press recently, one healthcare worker revealed that she and her colleagues are often well-aware of what variations of sex their patient prefers, and can even tell how often they like to give and receive oral pleasure.

But how? Well, apparently, there's a tell-tale sign - a 'fun fact', our medic says.

"How can your dental provider tell you have participated in oral sex?" Dr Britany Baker, recently asked her Instagram followers in a viral vid, before replying: "Palatal petechiae."

After having 'gone down' on someone with a penis, the mouth is said to show distinct changes within its tissue, that last up to three days after the raunchiness has subsided.

More specifically, these changes refer to a rash of pin-point sized reddish-purplish marks that appear at the back of the mouth.

Known in the industry as 'palatal petechiae', the phenomenon describes bleeding that has been triggered beneath the tissue, in a similar way to how a bruise forms in other areas of the body.

"Basically a hickey on the roof of your mouth," Dr Murphy continued.

Whilst oral sex isn't the only cause of the condition, she added - with illnesses like Covid-19, strep throat, or glandular fever often causing similar bruising - it is commonly the culprit.

It's caused by something hard repeatedly, or aggressively, hitting the back of the mouth, and paired with the pressure created with a sucking action, this triggers blood to rush to the area to a more extreme degree.

Another dentist, Dr Huzefa Kapadia recently chimed in on the x-rated revelation, claiming on TikTok that he's always able to tell how vigorous the oral sex was.

'If it's repeated abrasion in that area, we can tell," he explained. "Everyone is different, I can't say for certain that just because you've had it the night before it's going to show up at your dental exam.

"It all depends on how vigorous the action was... and how sensitive you are, like some patients bruise really easily while others may not bruise at all."

In most cases, these marks heal on their own, and may only require further investigation if they remain prominent for some time, as this type of bruising can be liked to blood disorders or cancer.

That said, however, if your bedroom antics align with your next dental check-up, it might be worthwhile postponing oral sex until afterwards, so as not to receive a funny look from your hygienist.
