Observant Jews residing in communities with strict dietary standards often prefer using toothpastes certified as kosher, particularly during the holiday of Passover when products must be entirely free of leavened grain derivatives. While standard commercial toothpastes do not necessarily need rabbinical certification for year-round medical use since they are not ingested as food, many families opt for kosher-certified brands to ensure compliance with Passover restrictions or avoid certain animal-derived additives. Major agencies publish lists of acceptable options annually.
