Guys, I have available two (2) certificates for professional one hour teeth whitening, identical to BriteSmile but called ZOOM! They are done by professional dentists. I'm sure most of you have heard of it. Anyway, these professional 1 hour teeth whitening treatments costs around $500. I have two fully paid for certificates for $150/each or $300 for both. The office is located in Glendale. I bought them for family members who are not interested in the treatment so am now selling these at a bargain price.
