      Strange tastes after brushing your teeth

      Strange tastes after brushing your teeth

      Why do some food and drink taste bad after brushing your teeth?  

      The main culprit here is a foaming and wetting agent found in most conventional toothpaste called Sodium Laureth Sulfate, also known as Sodium Lauryl Ether Sulfate (SLES), or Sodium Lauryl Sulfate (SLS). SLS has the ability to inhibit the receptors that detect sweet-tasting compounds.

      Additionally SLS can break up the phospholipids of fatty substances on the tongue that keep bitter tastes from being too overpowering. When these phospholipids are broken down by the SLS, bitter tastes become enhanced. This is why when drinking orange juice after brushing your teeth you are likely only tasting the bitter citric acid or citrus bioflavonoids until the SLS can be fully removed from the oral cavity, either by ingesting it with saliva or rinsing with water.

      SLS is an ingredient that would be best to avoid, especially putting in your mouth. (The bucal membrane is one of the most highly absorbable areas of the body). SLS is the esters of Sulphuric acid – also known as “Sulfuric acid monododecyl ester sodium salt”, the result of the ethoxylation process as previously discussed here
