Miley Cyrus Made a Super Questionable Hygiene Choice That Will Gross You the Hell Out

I'm not OK right now.

Miley Cyrus and her on-stage strap-on have made it clear she's throwing any f--ks she's ever given out the window. But there's just one f--k she should consider holding on to. That would be called personal hygiene.

Last night, the armpit hair advocate posted a nasty photo to her Instagram, where she's wearing someone else's retainer.

"When you wear your bffs retainer lol," she writes.

Ew.

I'm no dentist, but here's a little bit of the science that proves how truly disgusting this is. 1 Dental says a retainer is basically a cesspool of "excessive germ buildup," and "everyone’s mouth contains hundreds of different bacteria."

But this is the worst; there are two types of germs that aren't normally found in the mouth, however are found in over half of retainer wearers. They are:

  • Staphylococcus (Staph infection)
  • Candida (a type of yeast/fungus)
  • I need to go shower.
