Hi OTREBORC, Unfortunately I am not familiar with minty fragrances but I hope someone more knowledgeable than I can provide some suggestions. For the time being Parfumo's Avanced Search may be of help. You can filter for any note(s) you wish, e.g., peppermint, see pic attached. Good luck!
For a subtle minty toothpaste vibe try "Hugo (Eau de Toilette)" by Hugo Boss. It's not solely mint toothpaste-y but that essence is there. For a more blatant toothpaste scent that is highly satisfying try Bath and Body Works' "Twisted Peppermint".
Hi, CK "Euphoria Men (Eau de Toilette)" is the first one that comes to my mind for toothpaste. Funny because it doesn't even contain mint/peppermint. I once wrote in a comment that I felt like accidentally applying too much toothpaste on the toothbrush and sticking it into my mouth.
