Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ahmad ibn al-Hassan from ‘Amr ibn Sa‘id from Musaddiq ibn Sadaqah from ‘Ammar ibn Musa who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who extracts his tooth when fasting. He (the Imam) said, ‘No, and one must not make his teeth bleed or brush with a fresh twig.’” وثق - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/293))
