I heard recently in the name of Rav Schachter that you can consume Listerine strips on both Yom Kippur and Pesach without worry.

I wonder if anyone can confirm this, and explain to me why and how it would be okay? It'd sure change my Yom Kippur...

EDIT: These are the products that I am talking about: http://www.listerine.com/products/pocket-paks-oral-care-strips

Could you describe what these are or link to a product description? Thanks. – Monica Cellio May 10 '13 at 21:47
Sure, these are they: listerine.com/products/pocket-paks-oral-care-strips – WhoKnows May 12 '13 at 1:11
Why would you think these would be a problem? You don't eat anything. It just dissolves in your saliva. – Double AA May 12 '13 at 1:46
Well I suppose exactly because of that :) You definitely swallow something that you wouldn't have otherwise been able to. – WhoKnows May 12 '13 at 3:11
Which Rav Schachter? – Adam Mosheh Oct 25 '13 at 2:07

You can listen to him discuss it here at 56:12. He says it isn't rau'i l'achilat adam (fit for human consumption) so it isn't considered eating. He quotes some opinions that it is a problem of washing the inside of the mouth on Yom Kippur, but he doesn't seem so impressed by the idea.

Awesome. Exactly what I wanted. Thanks. – WhoKnows May 12 '13 at 3:12
