✅Answer: Please pay attention to the following narration on this matter, which was narrated by Shaykh Saduq and Shaykh Kulayni (may God have mercy on them both):
1 عن عَمَّارُ بْنُ مُوسَی السَّابَاطِیُّ عَنْ أَبِی عَبْدِ اللَّهِ علیه السلام فِی الصَّائِمِ یَنْزِعُ ضِرْسَهُ قَالَ لَا وَ لَا یُدْمِی فَمَهُ
📚 Al-Faqih, vol. 2, p. 70
📚 Al-Kafi, vol. 4, p. 112
Imam Sadiq (peace be upon him) said about a fasting person who extracts his tooth: 'No (he should not do this), and he should not make his mouth bloody.'
اللَّهُمَّ صَلِّ عَلَی مُحَمَّدٍ وَ آلِ مُحَمَّدٍ
وَ عَجِّلْ لِوَلِیِّکَ الْفَرَجَ وَ الْعَافِیَةَ وَ النَّصْرَ
