High-magnification images of enamel and dentine
by Healing Teeth Naturally © 2010
The following greatly enlarged pictures of enamel and dentine have been eye-openers for me since they clearly show that teeth are not the hard solid mass we conceive them to be. Note: some/all of these images are/may be copyrighted even if not attributed here. Please contact me if you have more information.

Note the hollow tubules structure which allows the tooth to be resilient to pressure (such as from chewing hard food items) rather than breaking under the stress. The tubules also provide excellent protective "housing" for bacteria once they have gained a foothold in the tooth.
"Undamaged dentin tubules contain a nutrient-dense fluid that keeps the teeth alive and healthy. These nutrients are supplied daily to each tubule by the artery that accompanies the nerve and vein in the root canal [compare illustration under Tooth]. The artery does this in the same way that other arteries supply nutrients to every cell of the body. ...
[I]f the tubules of a front single-root tooth were stretched out on the ground they'd stretch for three miles!" (Dr. George Meinig, see Root Canal Treatment - Is There a Coverup?)
Each square millimeter of a tooth has 45,000 microscopically small (hardly larger than bacteria) tubules running through it.
