Great for teeth without fillings or other uneven surfaces [SEP] Great for teeth without fillings or other uneven surfaces.  For me, when I did my best to spread it onto thinning teeth (bruxism ruined my teeth), it just look like I ate lots of macaroni and cheese and didn't bother to brush my teeth.  Wish they could invent a batch that didn't show every crevice in a person's tooth.
