The toothpaste becoming a foamy, more fluid liquid maybe a problem of [[molid]]. This problem is raised based on Rashi ([[Shabbat]] 51a) which says its asur to squeeze or crush ice on [[Shabbat]] because of [[molid]].<ref>(a dirabanan issur of changing form because it’s so creative it’s like a quasi-melacha.(Shu”t Maharal Diskin 66)</ref> Shulchan Aruch however holds like the Rambam saying [[squeezing]] ice is asur because it looks like [[squeezing]] fruit which falls under the category of [[sechita]].<ref> Shulchan Aruch Orach Chaim 320:9 based on Rambam Mishneh Torah Hilchot [[Shabbat]] 21:13. This same machloket applies to the permissibility of using a bar of soap. Shulchan Aruch (326:10) permits it, but the Rama there forbids it because of [[molid]].</ref>

*Rav Yitzchak Yaakov Weiss<ref> Minchat Yitzchak (3:50) </ref> prohibits brushing teeth with toothpaste based on this also.

*Rav Ovadia<ref>Yabia Omer OC 4:29</ref> paskins like the Shulchan Aruch that Sephardim don't have to worry about [[molid]]. He adds that Ashkenazim should hold like the Rama and brushing teeth is forbidden for them.<ref> Yabia Omer Orach Chaim 4:28 </ref>

*Rabbi Herschel Schachter<ref> Rav Schachter is quoted by Rabbi Aryeh Leibowitz between 2:30 and 3:30 http://www.yutorah.org/lectures/lecture.cfm/752802/Rabbi_Aryeh_Lebowitz/Ten_Minute_Halacha_-_Brushing_Teeth_on_Shabbos </ref> holds that even for Ashkenazim it should not be a problem because [[molid]] is solid to liquid not paste to liquid.
