i think the basic purpose is to keep your mouth and teeth clean,ab us zamaane main to miswaak hi available thi ab ager hum log brush regularly kerte hain to vo bhi theek he.
main nay dekha hai kaafi log abhi bhi miswak krtay han but not new geberations
miswak kernay main kuchh waqt lagta hai jab kay aaj kal 2/3 min main brush ker lo ya is say bhi kam
beherhaal miswak kerna sunnat hai koshish kerni chahiye pervi ki
I will try to continue
