Inspired by this thread…
So, you meet someone new, you like them, they like you (kinda-sorta) and you are both awkwardly fumbling into that kiss.
Sure, its probably the last thought on your mind, but are you really ever going to think after a 3-count “Bleeeech! Crest Regular!? What the Hell…!?”
I brush well with Colgate twice a day and my wife seemed cool with it, but when I switched to Toms of Maine (its amazing what you’ll buy with a coupon) she suddenly was holding kisses longer seemed to be generally enjoying her kissing more.
I guess the question really should be does the toothpaste your partner uses matter? Is there one you like your partner using? Is there one you’d like your partner to stop using?
Keep in mind, this has mothing to do with frequency (Kenneth, this means you) and its assumes the brush is actually out of their mouth at the time.
Everyone in my house uses Vanilla Mint Listerine after brushing, and that will certainly do away with any remaining taste of any brand of toothpaste! 
Seriously, if I’m going to kiss someone new (or even the same guy I’ve been happily hangin’ out with for more than 25 years. . .) the only important thing to me is that they not have bad breath.
I really can’t tell what brand of toothpaste someone uses by kissing them. Unless it’s immediately after brushing, all I can tell is *if *he uses toothpaste.
I used to see a girl that would always make both of us eat a mint or chew gum or something before we could kiss. It bugged me because there wasn’t really a chance to be spontaneous. She said she had always done that, so it wasn’t just me.
It’s not about the toothpaste.
Maybe she’s just trying to encourage you to use more coupons.
Actual good brushing skills (like, removing each and every remnant of food - especially meat) are far more important that toothpaste brand.
Is that it? Cause then I’d be all ‘clip, baby, clip’.

Dammit, who took the Living section…!?
I asked a couple of men I dated to go get their teeth cleaned. They were like, what is that? I haven’t been to a dentist in 20 years! I’m like, Yeah I know… and your plaque breath is enough to knock over a Rinocerous. 
Serously, All the toothpaste in the world won’t clean below the gum line! Plaque stinks because it is bacteria. Get your teeth cleaned once a year.
