This is what happens when you don’t brush your teeth.

Not only that, but it is up there on the gross scale with the plethora of spot-popping videos that we have discovered and published in the past.

It shows the inside of the mouth of a man named only as Katsu during his first visit to the dentist in 10 years, according to the video’s description.


It reveals the consequence of a build up of Japanese food and smoking without flossing.

That causes plaque which in turn hardens to tartar which requires dental treatment to remove it.
