How many Shades will my teeth whiten by?

[Lisa]

I am considering Zoom whitening. I have really dark teeth because I used to smoke. I have now stopped smoking for 2 years. Now I really want my teeth to be whiter. Does anybody know, by how many shades Zoom whitens teeth?

Hi Lisa,

The analysis of 500 Zoom! Chairside Whitening cases performed across the United States showed an average improvement of 8 shades using the VITAPAN™ System shade guide. The results showed that the darker the teeth, the greater the whitening effect.
