When one of your front teeth is freakishly alligned with your septum.

Check out Tom Cruise and his fugly unitooth!

Unitooth 

When a person's teeth are so grungy, they appear to be fused together.

Don't grin so wide with that unitooth you got going on!

unitooth 

A freakish row of teeth that, like a unibrow, seems to consist of a single mass of unbroken, tooth-like substance when a person smiles. Akin to a mouthguard made with a single, gigantic tooth.

I am sick of seeing Tiger Woods and his ridiculous unitooth on TV all the time.

Unitooth 

A singular perfectly centered tooth. Most like an incisor.

Wow, I always thought Tom Cruise was handsome until I noticed his unitooth.
