Have had a problem with bad breath so have tried using the tooth guard and have found it really good I was a bit worried about the price so I cut each tablet into 4 with a pill cutter and let just one dissolve really slowwwly in my mouth at night (after brushing) so now one box lasts 4 months but these things really work, and have since decided (just like the marketing manager) to buy some shares in it.
looks like its getting momentum overseas
