6. Human Teeth Under a Microscope
Teeth look incredibly bizarre (and pretty disgusting) under the microscope.

Under a microscope, it’s easy to see where the enamel has deteriorated and been replaced with cavities and plaque. The picture below shows cavity-causing bacteria interacting with other microbes in the mouth and on the teeth.
