Assalamualaikum, You have not understood the sunnah of miswak. Prophet (saw) did miswak when he (saw) entered his (saw) house, prophet (saw) did miswak when he went to sleep, prophet (saw) did miswak when he woke up e.t.c in many places prophet (saw) did miswak. Miswak can not be brought to the level of electric sonic, tootbrush, dental floss and moutwash. If it was, then will a person do mouthwash when he enters his house, goes to sleep, wakes up? or brush his teeth? or use dental floss? prophet (saw) used miswak in many places, and to apply yourself and to copy the way of prophet (saw) is way better.
