ELI5: does gargling mouth wash actually do anything? What's the best way to keep your teeth clean (beyond brushing)?

It does, it has antibacterial properties as well as forming a sort of protective coating on the tooth surface that prevets plaque buildup. It also reaches places where the toothbrush struggles. Other than that you  should also floss as that removes debris between the teeth that are otherwise hard to reach.
