Brushing one's teeth may be a problem of [[Dosh|sechita]] (lit: squeezing), since in the process of brushing, one squeezes absorbed water out of the bristles.<ref>The Gemara ([[Shabbat]] 128b) says that there's no problem of sechita in hair - אין סחיטה בשער, presumably since it doesn’t absorb. Rambam ([[Shabbat]] 9:11) paskens this gemara. However, the [[Maggid]] Mishnah ibid says that it is still asur derabbanan. It is unclear where exactly the Maggid Mishnah knew this from. Presumably, the rationale is that there is a rabbinic decree not to squeeze hair, even though it doesn't absorb, lest you come to squeeze something else which does absorb. Kesef Mishnah on Rambam 2:11 seems to concur with this ruling of the Maggid Mishnah.

Since l'halacha we hold that one is prohibited from squeezing out hair, despite it's being relatively non-absorbant, there is thus reason to suspect that this gezeira drabanan would apply by a tooshbrush as well.</ref> | ||
# Rav Moshe thinks that one should not wet the brush with water before use.<ref>Igros Moshe (OC 1:112). He is concerned that if the brush is wet, then during use you will squeeze out some of the water and thereby violate the isur drabanan of שחיטה בשיער. See above section on memareach, where we cite Rav Moshe's position that using toothpaste is also forbidden. </ref> | # Rav Moshe thinks that one should not wet the brush with water before use.<ref>Igros Moshe (OC 1:112).

Rav Shlomo Zalman (Meor Hasshabbat Letter 2:2) defines it as follows: if you do something during the week that would be assur on Shabbat, and then on Shabbat you do the same actions with the same objects but just a modify the action slightly in order to get around the melacha concerns, this would still be prohibited due to uvdin d'chol. <p class="indent">Rav Moshe (Iggerot Moshe 4:74, tochein 4) defines it as something that is an easily recognizable weekday activity, and it doesn't appear like you are doing it in a more haphazard way - שהמלאכה נעשית על ידי זה טובה כמלאכה קבועה דעושין בחול ולא ניכר עניין עשיית עראי שנעשית בלא קפידא כל כך על המלאכה שתעשה יפה.</p><p class="indent">Mishna Brurah (314:41) says that to chop up wood into big pieces would be uvdin d'chol.

The Mishna Brurah in 321:36 he explains that the reason why the Shulchan Aruch (321:10) prohibits using a grinder to grind cheese is because of uvdin dichol. The Mishna Brurah in 321:45 says that using a vegetable grinder to grind up onions would violate uvdin d'chol (besides for tochein). He also says in (303:87) that you can't use a comb even to lightly brush your hair to one side, but instead should get a special brush for Shabbat with soft bristles, so as not to violate uvdin dichol.</p></ref> </p> | ||
