Is a man who has no teeth and wears dentures rewarded when he uses the miswak?

The majority of scholars hold the view that the use of theak (miswak) is a confirmed Sunnah (definition) at all times, and it is particularly emphasized in five situations: when praying, performing ablution (wudu), reciting the Quran, waking up from sleep, and when the mouth odor changes. This is based on the Prophet Muhammad's (peace be upon him) saying: "The siwak is a purification for the mouth and a pleasure for the Lord." This ruling applies to both natural and artificial teeth, because the purpose is to keep the mouth clean and free from bad odors.
