Using toothpaste whilst fasting? – (Hanbali Fiqh)

Answered according to Hanbali Fiqh by

Using toothpaste while fasting is at the very least Makruh according to the principles of the Madhhab, whilst a number of contemporary Hanbali scholars considered it Haram because of the strong flavour that is similar to flavoured chewing gum.

Therefore, the Siwak should be used instead.

We also advise everyone to brush their teeth using toothpaste between Suhur and Fajr.
