I can just picture these little cells with teeth...
I’ve seen this before, and speaking as someone who has easily put a dentist’s kid through college, I will ask the question:
Considering that a good number of my darned teeth rotted out, WHY would I want to spend a lot of money and go through considerable discomfort for new teeth just like them?
I’d much rather have clones of someone elses’ teeth, who actually has GOOD teeth with GOOD enamel.
