Title: Doesn't Last on Tongue
Product review: Bought this on the rcommendation of a pharmacist for a sore on my tongue. It does numb the spot, but doesn't last anywhere near what other reviewers are claiming. I get about 10-15 minutes of relief at most, then it just disolves away. Maybe works better on a canker sore, but not on a tongue sore. I guess if you could completely avoid touching your tongue against anything inside your mouth it might last longer, but that;s pretty much impossible, so I can't recommend it at all for this use.
