REALLY WORKS!!!!!!
The pens are very easy to use.  I used twice a day and it took 6 days for my teeth to reach the white level I required.  Easily maintained with simple painless applications.  No worry about irritating gums as with other teeth whiteners.<br />I would recommend this to anyone wanting whiter teeth the easy way.  It is important that the areas are dry when applying and nothing is eaten for about l/2 hour after application.<br />just remember to follow application directions for whiter looking teeth in no time.
