while he is also selling his own brand of mouthwash, i find his information trustworthy since he provides sources.

as always, take with grains of salt. just don't tub the grains on your teeth.

fwiw, i also hate toothpaste. more so because of anxiety about swallowing it and it not being edible/safe to ingest. so i went through phases of researching this topic, and it's indeed hard to find supporting info.

the TL;DR is that fluoride is beneficial but the delivery system doesn't need to be paste form, neither does the system need to have mint flavor, sweeteners, peroxide, baking soda, micro beads, whitening, any of that junk.

furthermore, if dentists are really pressed, some admit that the physical action of brushing (and flossing) is the bare essential minimum needed. this is also mentioned in the video, i believe.
