Does brushing one's teeth with toothpaste invalidate fasting?
Can a person who performs supererogatory (nafilah) fasting brush his teeth with toothpaste?
Dear Brother / Sister,
A brush is likemiswak; according to to fiqh, it is regarded as miswak. According to Hanafis, a person who is fasting can use a miswak or brush whether it is dry or wet any time, before or after noon.
However, according to some narrations, Abu Yusuf states that it is makruh for a person who is fasting to use a wet miswak
According to Shafiis, it is permissible to use miswaq before noon but makruh after noon. To sum up, According to the preferred view of Hanafis, it is permissible to use miswak (brush) any time.
According to Imam Abu Yusuf, it is makruh for a person who is fasting to use a miswak and brush wetted by water. However, according to Abu Hanifa and Imam Muhammad, it is not makruh for a person who is fasting to use a miswak or brush wetted by water.
However, it is definitely makruh to use a toothbrush with toothpaste for a person who is fasting; it is necessary to avoid it. However, fasting is not invalidated unless the toothpaste is swallowed.
