Does Brushing Teeth With Toothpaste Break the Fast?

Question: 13619

Is it permissible to brush one's teeth using toothpaste when fasting? As far as I know, it is permissible as long as the toothpaste is not swallowed. Please give your input on this.

Summary of answer

Brushing teeth while fasting will not break the fast. So, you can brush your teeth using toothpaste while fasting so long as you are careful to avoid swallowing any of it.

Answer

Praise be to Allah, and peace and blessings be upon the Messenger of Allah and his family.

Shaykh Ibn Baz (may Allah have mercy on him) was asked about using toothpaste whilst fasting.

He said:

“There is nothing wrong with that so long as one is careful to avoid swallowing any of it, just as it is prescribed in Islam for the fasting person to use the siwak (tooth-stick).” (Fatawa al-Shaykh Ibn Baz, 4/247)

Shaykh Muhammad al-Salih ibn ‘Uthaymin said:

“… This leads us to the question: Is it permissible to use a toothbrush and toothpaste whilst fasting or not?

The answer is that it is permitted, but it is preferable not to use them because the toothpaste is too strong and may go down into the throat. Instead of doing that during the day, one should do it at night.” (Al-Sharh al-Mumti’ by Ibn ‘Uthaymin, 6/407-408)

And Allah knows best.
