Love Island fans are in uproar after noticing this year's stars are brushing their teeth wrong.
All of the Islanders have been provided with an electric toothbrush to keep their teeth (and veneers) looking pearly white.
However, some viewers have noticed that many of the contestants are doing the basic task completely wrong and have called for a dentist to enter the villa.
They have pointed out that some of the Islanders are using their electric model like a manual one.
This might not sound bad, but dentists say it puts too much pressure on the gums and erodes enamel on the teeth.
This in turn can cause the gums to recede, with the loss of enamel leading to sensitivity.
Both of these negative results are irreversible and can do some serious damage.
This series' contestants have also been slammed for using an electric toothbrush on their tongues.
Love Island fans have taken to Twitter across the series to question the dental skills.
One viewer asked: "Can the #loveisland producers teach the fools in the villa how to use an electric toothbrush please??"
"These guys have no idea how to use an electric toothbrush," added another.
A third agreed: "Get me into that villa to give them an electric toothbrush demo!!!
"That Love Island pet hate I have - they have rotary electric toothbrushes but insist on using them back and forth like a normal toothbrush," said a fourth.
While others complained about some of the stars using their electric brushes on their tongues.
"WAS THAT MAN USING AN ELECTRIC TOOTHBRUSH ON HIS TONGUE I JUST PHYSICALLY FLINCHED," gasped one viewer.
Another added: "For real tho who TF cleans their tongue with the toothbrush? Acc ALIEN SHIT man x"
"No one should be scraping their tongue with their toothbrush like that Michael!!!," said a third.
*Love Island airs tonight at 9pm on ITV2
