Scientific facts abt the wisdom tooth

can you believe my wisdom tooth kinda look like the one on the left? the one with 2 roots!! well that's the one from my upper row and the real killer was the one at the bottom... it gat 3 roots!!!! well it sure was hell... btw this photo of the 2 teeth are not mine la... it's ancient hahaha... well it is said tat our bones and teeth are the hardest to decompose.. or maybe not at all....

ok now for the scientific fact abt why the wisdom tooth is soo big that it will bore you out hahaha...

There's a balance between two molecular mechanisms, Activation and Inhibition, govern how many teeth form from the tooth germ (the small bud of tissue that will later form the tooth) and how big the teeth are.

When the two mechanisms are in balance, all three teeth form and are about the same size.

But if the two don't balance, the size of the teeth differs. If Activation wins out, each tooth is successively larger, with the wisdom tooth becoming the bully of the bunch and causing a real mouth-ache. In extreme cases, a fourth molar might even rear its ugly head.

On the other hand, if Inhibition wins out, the teeth get successively smaller, so the wisdom tooth is the runt of the litter. Run to its extreme, this situation could prevent the wisdom tooth from forming altogether.
