If you're anything like me, one of your worst nightmares involves having your teeth damaged. Even with public healthcare, dental work does not come cheap and that's not to mention the damage it does to your appearance.

Now, Jason Derulo has posted a video of himself "knocking out" Will Sith's teeth with a golf club to Instagram, and all we can say is that we are shook.

Derulo captioned the video, which, at the time of writing, has been viewed a million times: "I don't like this game @willsmith".

Watch the dramatic moment Smith's teeth are "knocked out" below:

To begin with, it looks like a fun snippet of Smith, 51, trying to teach his friend some golf moves, but it's not long before things take a disastrous turn for the worst.

As Smith tells the 31-year-old that it's a good idea to film your swings so you can watch them back to critique yourself, Derulo prepares to swing and Smith moved away from the camera before saying: "Wait, hold it - don't swing yet".

Smith then approaches Derulo as he swings the club back and... you guessed it, he hits Smith right on the face.

As Smith frantically rushed to assess the extent of the damage, Derulo says: "Put some ice on that... I got a thing."

While Smith said: "It's my turn, my turn. I only need one swing. I only need one swing. Let me get my driver."

After grabbing his own club and approaching Derulo, he pleaded: "Alright we can talk about this."

Thankfully, however, Smith doesn't appear to be in that much pain, so it's safe to assume that this was nothing more than a well-timed prank.

After all, the two posted this grinning selfie afterward.

For obvious reasons, we don't recommend emulating this one at home.
