There are 2 jaws-just bones,really.Both part of the skull,both hold teeth.The upper (maxilla) and lower (mandible) meet at the Tempromandibular Joint (TMJ).You're right in that only the lower moves, this through the interaction of half a dozen facial muscles.

Wisdom teeth? God's gift to oral surgeons I guess.How else could dull, myopic, humourless individuals earn such a lucrative, if mindnumbingly boring living. Seems like they almost never fit properly (the wisdom teeth-not the oral surgeons).I have heard many suppositions regarding why they're there and why they don't fit.None definitive nor overly convincing.

Does this qualify for the most boring part of any thread ever on Mudcat? Sorry folks.
