I think there’s more to it than that. Very bad dental hygiene has a risk of endocarditis. Bacteria can enter the bloodstream through damaged mucosa in the mouth and colonize heart valves. I’ve seen it proposed for years now that this happening to a lesser extent can contribute to systemic inflammation that contributes to cardiovascular disease.

Edit: Also the study found mouthwash itself doesn’t do a damn thing.

As to the edit, what we mean by 'mouthwash' kind of matters. Like certain types of bacterial infection can be exacerbated by Listerine and the like, where cheap as dirt hydrogen peroxide or simple salt water can be beneficial.
