When brushing your teeth with baking soda it's recommended to brush your teeth with baking soda 2 to 3 times per week or brush your teeth with baking soda everyday but also during those days brush your teeth with normal toothpaste that contains fluoride because the fluoride helps to keep your teeth from decaying.
But the baking soda is also good for cleaning your teeth.
Brushing your teeth with baking soda is a good thing and baking soda does work great at naturally cleaning your teeth.
However it's also recommended to use toothpaste with fluoride because the fluoride helps to keep your teeth healthy and strong and prevents tooth decay.
So while it's good to brush your teeth with baking soda you should still brush your teeth with some fluoride toothpaste as well.
So no it's not better to brush your teeth with baking soda but brushing your teeth with baking soda is good and helps keep your teeth clean as well.
I use baking soda to brush my teeth every few days but the rest of the days I use my regular toothpaste that contains fluoride to keep my teeth clean and healthy and to prevent tooth decay.
I also recommend doing oil pulling for your teeth and using apple cider vinegar to kill bacteria in your mouth by gargling with the apple cider vinegar.
