Teeth do require a huge amount of care, especially amongst children. Open gaps where baby teeth used to be could invite unwanted bacteria. Usually, parents would tell their kids to throw them away after they dropped out, or the dentist would do so. But no one would expect that baby teeth are of great importance to the medical and healthcare industry.
Losing baby teeth and making room for fully-grown ones seem normal, but now people are starting to keep them – for one good reason: you can sell them to medical labs!
Perhaps you have heard of the culture and myth of slipping your milk teeth underneath your pillow in hope that the tooth fairy would come visit and exchange it for a dime or two?
This is modern tooth fairy work – but not of the magical kind, unfortunately.
