Abstract
The present invention is a mouth swab which comprises a support stick having a swab mounted on at least one end thereof. The swab is impregnated with an oral treatment composition (e.g., a mouth freshening composition) and is encapsulated with a dry, saliva-soluble polymeric coating. Placement of the swab in the mouth results in dissolution of the polymeric coating by the saliva in the mouth and allows for release of the oral treatment composition into the mouth cavity. In certain preferred embodiments the product can contain either a dental floss or toothpick implement within the support stick.
