Toothpaste also bears some abrasive that contributes to "scratching" the enamel and in general also some detergent. They can also contain colorants, preservatives, bleachers for the teeth, anti microbial agents...many of them unnecessary. The ingredients may be natural (mineral or vegetal) or synthetic. The latter are associated with problematic aspects as the dependence of raw oil or undesirable interactions with the organism. Let us try to put in our mouths the less synthetically substances as possible.
The toothpaste helps the toothbrush and provides freshness. A little bit is enough.
There is quite a lot of toothpaste that use almost exclusively vegetal and mineral ingredients.
