– Q. Moreinu Verabenu Shlit’a. I have a problem this year. (2025), how do I brush and clean my teeth after eating chametz on the morning of Shabbat, since I don’t brush my teeth on Shabbat?
A. On question 3096 we wrote:
“ Q. How does one clean his teeth on Shabbat this year when Erev Pesach is Shabbat?
A. One can rinse one’s mouth and use Kosher Lepesach mouthwash and a floss pick or similar, being careful not to draw any blood. As mentioned in a question above, one may also use a soft dry toothbrush without any paste at all.”
