Opposite-taste gum

How about this for a new gum product. A gum that produces the opposite taste in the mouth. Did you eat something too salty you're about to throw up? Even if you drink water you'll still have a nasty feeling. Chew the opposite-taste gum which detects saltiness and reverses the taste in your mouth to something sweet. Ate something too hot and chilly? The gum leaves a cool feeling. Its flavor stays neutral, it'll be like a pill to have in your wallet in case of emergency. Restaurants and shops that usually have regular candies by the entrance should stock them too.
