Use cold plasma to put essentially transparent gold,
platinum, or Vernon: Iridium film on the tooth surface.
direct laser writing (DLW) to make waveguides which are
the things that produce the light bending effect.
[Wikipedia link Flat Lenses] Wikipedia says flat lenses
can be made
with films as thin as near 200 nanometers.
Durability unknown but making the microstructured flat
lens waveguides from osmium might be tough and
unreactive enough. Cold plasma diamond deposition is
also published, but there it says cold is 600 C.
Then, I think, clever optics like offset prism equivalents
cause almost pure blue light to be line of sight to the
teeth. Just as optical brighteners add blue to yellowed
linens to make them appear whiter, the teeth appear
It would be nice if it could be advertised as laser tooth
whitening that lasts a decade with one office visit!

||Osmium chemically reacts with oxygen in the air, yielding a
toxic substance. You should be recommending iridium
instead, with more resistance to corrosion than platinum.
||Thanks [Vernon] for your iridium suggestion.
||I also wonder if it is possible to laser write waveguides
directly on teeth but the nonhomogenaity and porosity
make that seem unlikely.
||Instructions unclear, my teeth are now green.
||I tried this with Lasix and now my race horse has whiter teeth.
