An urban explorer has shown what it’s like inside a dentist’s abandoned mansion, with rooms filled with old dentures and needles still ready to inject patients.

The explorer from the US, who prefers not to be named, shared the surreal experience on his social media pages under the name Triangle of Mass after returning to the property twice to try and film.

In a video shared on TikTok (@triangleofmass) the explorer pans round to reveal an old abandoned dentist chair, with a needle still being held up by an arm on the chair.

The clip shows how the mansion has practically been left frozen in time.

As he continues to move through the property he reveals dozens of teeth moulds, old dentures and dental tools.

Teeth charts also sit in a box, ready for cavities to be marked off, though it’s been a long time since a patient has sat in that chair.

“Horror movie vibes” said one user.

Another viewer said: “Looks like my childhood dental office.”

“It’s weirdly pretty,” added another person.

Someone else said: “You’re finding such amazing things I’m really obsessed videos to.”

“How do you find and access these places! It's so beautiful fascinating and interesting,” said another viewer.

“The creepiest thing I found in there was that whole room, the entire house just sits there and then all of a sudden you’re inside a radio station as well as a dentist office with all the equipment still there – with moulds of teeth and so on,” the explorer told NeedToKnow.online.

“It’s like you took a wrong turn and it’s a whole different place you’re exploring, with the power that’s just been left on and you can hear the fridge on the upper floor screeching as its motor is about to die from running so much.”
