Re-Grow Tooth Enamel

It difficult and very time consuming to clean my teeth with miswak. The hairs are too soft and always get out of shape and have give them a toothbrush shape every little. But because it is too soft it is good for the tongue. Its head is small so one has to do one tooth at a time and takes a little toothpaste on. It leaves the tooth shiny but doesn't remove the hard plaque. It must have been good some centuries ago! I'm giving up using it because it is too time consuming and doesn't have eve the results of a common plastic toothbrush let alone sonic and other electric toothbrushes. Because of the special movements one has to make with miswak he/she cleans his gums also and is gentle on gums. It lasts long.
