This pump bottle is 16 ounces, which is more than one month’s supply of this mint flavored tooth-brushing gel.  Once you try it, you won’t be without it.  Tastes terrific and with 35% xylitol it is effective in reducing plaque and the bacteria that cause cavities.  No need to spit out if you are not near water.  Can be brushed or simply swished and swallowed.
