I saw an x-ray of a human mouth with the second set "waiting" to erupt.  It got 
me thinking about control of the process.  I have been unable to find a WWW 
satisfactory explanation, apart from learning that there is research at Guys 
Hospital in London, where the lead singer of Dracula has been able to grow 
1.5inch incisors!  Control is genetic, I understand, but what triggers it all?  
What controls it all once it is triggered?  Is it true that some folk have 
THREE sets of teeth?
