Baking soda toothpaste is safe to use twice daily. However, people with sensitive teeth should gradually increase their use of baking soda toothpaste if they experience sensitivity.  

Generally, baking soda is not abrasive enough to harm teeth or cause dental damage when used regularly. However, if you develop sensitivity, you should stop using it.

Some dentists and researchers caution against the overuse of baking soda toothpaste. Sometimes, using baking soda can cause microfractures and scratches in the tooth enamel.

Microfractures and scratches weaken your tooth enamel’s structure. Weakened enamel may make teeth more susceptible to staining and make them more yellow and brittle over time.6, 7
