This commercial was for some sort of mouthwash or mouth spray or toothpaste. It shows a black and white closeup of a man. The camera zooms into the mouth to show germs floating around in his mouth. Then a few seconds later, he is happy with his kids. What mouthwash brand was this commercial for?

Listerine perhaps? I remember it was from the late 90s and I always thought the CGI image of the germs looked like they were floating in the ocean.
