My dentist would love this. An indication of a single “cavity atom” would trigger an emergency call-in from him. Gotta get those kids through college, you know.

Looks like it was carved out of sandstone.

Great application for a scanning tunneling microscope! Move a single atom of amalgam to fill the hole! Wait, that’s an alloy . . .


#5

That’s a thought. Perhaps move different atoms to end up with dental amalgam?


#6

sure is something to chew on


#7

Now let’s zoom out a bit more.
Oh, dear god, no!


#8

see, a spinach atom, right there…NO, on the other side.


#9

That’s the tooth.


#10

“Is it safe?”


#11

Of course now they use polymers cured by UV (as I found out a month ago). I don’t know how big those particular molecules are, but it would take a while to move the atoms in, one by one by one . . . .


#12

That would be where job security come into play.


#13

Isn’t this the opening of Fight Club?


#14

So how do I floss that gap between the atoms? Or what about the yawning void between the nucleus and the electrons? So much empty space there for food buildup.


#15

That’s where the electrolytes get in
