No. Listerine's "burn'n" is caused by the ethanol (54 proof grain alcohol) which is NOT an active ingredient used to kill germs that cause bad breath, and most importantly, germs that cause plaque and gingivitis.
From Wikipedia, the free encyclopedia Listerine (antiseptic mouthwash) First formulated by Lister in 1879 as a surgical antiseptic... Currently manufactured and distributed by Pfizer Inc. The active ingredients are menthol, thymol, methyl salicylate, and eucalyptol, all of which are structural isomers. Ethanol is present [and] does not have antimicrobial activity but serves to dissolve the active ingredients and to facilitate the penetration of the active ingredients into dental plaque.
