As-Salaamu ‘Alaikum Dearly Beloved Asiatic Black Queens!
Ask any Dentist and she will tell you that Baking Soda is the BEST product you can use to brush your teeth. Toothpaste has sugar and is much more expensive. So, you would be foolish to continue to spend money on toothpaste when baking soda is better AND cheaper!
If you ask any Dentist about using peroxide, she will tell you that it is excellent for oral care. If you ever have a sore throat, gargle with peroxide and it will eliminate the soreness. But peroxide is also known for whitening teeth.
Now, my Dentist told me to combine half water and half peroxide and rinse after I brush with the baking soda. Some people mix them together and make a paste. But I like doing it my way.
Now, I don’t know the chemistry but after brushing with baking soda, you have to rinse with the peroxide/water combination. It’s probably the pH, because if I don’t rinse with the peroxide/water, my mouth feels funny. I think the peroxide neutralizes the baking soda.
