Brushing Teeth on Shabbat
=Mimareach
The mishnah is Shabbat (73a) lists Mimachek as one of the avot melacha-scraping, removing a surface to leave a smooth remainder (sandpaper, scraping hairs off a piece of leather to make it smooth)
Mimareach-smoothing not by eliminating surface, but by spreading something over the surface. [1]
Rav Moshe Feinstein [2] says that it’s definitely assur to use toothpaste because of mimachek but without toothpaste its allowed just like washing the rest of your body. So seemingly, Rav moshe meant mimareach the toladah of mimachek.
Maybe he actually means mimachek that you’re smoothing out your teeth by removing the plaque. Rav Soloveitchik [3] said removing dirt or plaque is certainly not mimachek just like washing dishes is permissible. Mimachek is only when you’re removing something that is part of the essence of the object itself and plaque isn’t that. So they asked him maybe you remove enamel by brushing and he said that if that were true eventually you would have no tooth left from brushing.
Rav Ovadia Yosef [4] says even paste is allowed. [5] Rav Soloveitchik agreed to this [6]
The Tzitz Eliezer rules like Rav Moshe. <ref> Shu"t Tzitz Eliezer(7:30:8). He says that its not same as magen avraham because the spit the whole purpose is to get it into the ground, but with the toothpaste there is a purpose in the smearing even if just for a minute. (Says there’s no shiur for how long it has to be there)Cite error: The opening <ref> tag is malformed or has a bad name
