How often on average will the whitening last until it needs to be redone?
David C. asked on Feb 19, 2013
There is no average that can be applied to each patient. We have had patients who have bleached their teeth and the color has remained lighter for 20 some years. Others need to be touched up every 6 months. There are a multitude of reasons for staining and coloration of teeth and it is difficult to state what the "average" is until the cause of the discoloration can be ascertained.
