This may be a bit disturbing to you, but if you have been skipping your dentist appointment, then prepare to have this new set of teeth.
The sickening video above features a man who hasn't visited the dentist for 10 years.
And it is clear from looking at the inside of his mouth that he hasn't kept up with much of a teeth-cleaning regime either.
A YouTube video was uploaded by camp bar, the description of the video states that the "decade of calcite and plaque" was built up due to "authentic Japanese cuisine, smoking, and never having flossed."
In the one-minute-and-23-second clip, the plaque covered teeth are seen being cleaned, as over a decade of grime is chipped out of the man's mouth.
Named only as Katsu, the man has the whole cleaning procedure filmed before his teeth are uncovered again, looking much less brown.
The disgusting clip has had over 1 million views on the video sharing site, although it is unclear exactly where the footage was filmed - or by whom.
