What is the ruling on using toothpaste for the fasting person?

Question : The questioner asks: Is it permissible for a Muslim in Ramadan to use a toothbrush and toothpaste to clean his teeth?

Answer : Using the miswak while fasting is a recommended practice (sunnah) at the beginning of the day and at the end of the day. Those among the scholars who dislike it after the sun passes its zenith have no valid basis, in our view, to restrict the general evidence indicating the recommendation of using the miswak at all times. 'Amir ibn Rabi'ah (may Allah be pleased with him) said: .
He did not exclude any of the times of the Prophet (peace and blessings be upon him). However, some people use the miswak, and blood comes out of their gums. In this case, he must spit out the blood, and it is not permissible for him to swallow it, because blood is not saliva; rather, it is a specific substance from the body, not saliva.
As for using a toothbrush and toothpaste, that is divided into two categories. The first is a strong toothpaste with a substance that a person cannot hold in his mouth; rather, it runs down to the throat and then to the stomach. This type of toothpaste is not something a fasting person should use, because it endangers his fast. The Prophet (peace and blessings be upon him) said in a hadith of Laqit ibn Sabir (may Allah be pleased with him):
As for the second category of toothpaste, it is a light toothpaste that a person can fully control. There is nothing wrong with a person using it while fasting, and he lets his saliva wash it away until its taste disappears from it.
