Jaws 2: A Pig in the City

Today, after a childhood of battling bad teeth and cavities, I'm an overzealous brusher. I found out that I have cavities in all quadrants of my mouth from over-brushing, which will need multiple appointments to fill. FML

The brushing itself did not cause cavities, just weakened the enamel to the point it could no longer protect the teeth from the bacteria that cause it. Brushing away all bacteria in the mouth is impossible, and could end up removing so many of the harmless ones that only the bad bacteria remain.

The same thing happens in many hospitals, so much disinfectant and antibiotics around that only the dangerous, resistant strains can survive.
