عَنْ حُذَيْفَةَ رضي الله عنه قَالَ:
كَانَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ إِذَا قَامَ مِنَ اللَّيْلِ يَشُوصُ فَاهُ بِالسِّوَاكِ.

Hudhayfah (may Allah be pleased with him) reported:
When the Prophet (may Allah's peace and blessings be upon him) got up at night, he would cleanse his mouth with Siwak (tooth-stick).
