What brand of breath mints last the longest?

The advertisement for ForeverMints brand claims that they make the longest lasting breath mints. Once placed inside the mouth, a single breath mint lasts three hours during the day and up to eight hours overnight, before it dissolves.

The company explains that ForeverMints are made from all natural ingredients that release continuous mint flavor, while a xylitol sweetener kills the germs that cause bad breath and cavities. This tiny breath mint can easily be concealed between the gum and cheek to provide fresh breath and good gum and tooth health. The mint helps to relieve dry mouth, in addition to whitening and strengthening the tooth enamel.
