Question
Will brushing your teeth break your fast?
Answer
Praise be to Allah, and blessings and peace be upon the Messenger of Allah:
If toothpaste does not get into the throat, then the fast is not broken. However, it would be better to use toothpaste at night and to use Siwak in the day time.
May Allah guide us to His obedience!
