#5968 - Much More Mouthwash?
Question
See question above. How about using baking soda or similar powders to brush teeth?
Answer
If it’s put on dry without making a paste beforehand or you make a paste before Shabbos it would be permitted.
Yet only a Shabbos Toothbrush may be used.
Regarding tooth powder, besides the possible Shabbos concern, it should not be used even in middle of the week, because of
potential kashrus concerns.
