The only sure way to prove the real worth of any product is to test it . And new formula Colgate Plax, the pre-brush dental rinse, has just been thoroughly tested.
The whole trial lasted six months and involved men and women of all ages and from all walks of life. All were asked to rinse for 60 seconds before brushing：half used new formula Plax. the other half used a neutral coloured liquid but of course nobody knew which they were using.
The results were both dramatic and conclusive and have now been published. The half who had used rinsed with new formula Plax showed a 24% reduction in plaque overall. Those rinsing with the other liquid showed no reduction at all.
And now we've made Plax even better, with a coupon that saves you $ 2 off a new bottle.
We've proved that new formula Plax is dramatically more effective at reducing plaque than brushing alone. Clip the coupon and prove it to yourself.
