Or litzion 3:25:7 disagrees and says in that case she would only be exempt within thirty days of giving birth. This is also the ruling of Eishel Avraham Butchatch 550:1 </ref>

===Brushing One’s Teeth===
# According to Ashkenazim, one shouldn't brush one's teeth on a fast day unless one will be in pain by not brushing, such as someone who brushes daily. Since Tisha B'Av is more severe, one shouldn't brush one's teeth on Tisha B'Av unless not brushing will cause oneself major pain.<ref>Piskei Teshuvot 567:1 and Sh”t Minchat Yitzchak 4:109 hold that brushing teeth has the same status as rinsing one's teeth.

Furthermore, based on Rav Schachter's opinion that all toothpaste is kosher since it isn't a food, Rabbi Lebowitz posits that one can certainly make the argument that brushing one's teeth is more lenient than rinsing one's mouth and is permitted on a fast day.</ref> According to Sephardim, those who regularly brush their teeth with toothbrush and toothpaste may brush on a fast day with less than a [[Revi'it]] of water but they should bend over while rinsing so as not to swallow the water. <Ref>
