Doctors recommend Sensodyne Original Sodium Chloride Toothpaste to treat and prevent both damage caused by acid and sensitivity. It contains strontium chloride hexahydrate that ensures safety for your tooth and protects your teeth from damaging or getting harmed by chemicals and acids present in your food and drinks. You can use it twice daily as your regular toothpaste to get effective results.
