Anyone who has gotten a dry mouth when public speaking can attest to the difficulty that comes with a dry mouth! Dry mouth can occur when our salivary glands don’t produce enough saliva. Sometimes this means our body is dehydrated and lacks the fluid necessary to produce saliva. If this is the case, staying properly hydrated can help.

Dry mouth can be a side effect of certain medications, the result of radiation therapy, smoking and even diseases such as diabetes or Parkinson’s.
