On Thursday this week I needed a dental procedure. Seeing I was interested, my dentist took the time to explain a few things to me. I apologise to anyone who already knows this stuff:
Seems the pulp of teeth has no defence against infection. None. If bacteria get in, tooth becomes infected and will be lost if of not treated.
He agreed with my observation that teeth are not designed for long term use. Probably for around 20-25 years. A bit short of the biblical 3 score years and ten.
I’ve made this observation before; evolution is lousy engineer. Good enough is good enough. An evolved anything needs only to work, it does not need to be elegant . Could one not reasonably expect an intelligent designer to produce beautiful, elegant designs?
