For those considering doing the Zoom whitening before the wedding, I HIGHLY recommend it!! I just got it done yesterday and I am thrilled with the outcome! Unfortunately it does cause a lot of sensitivity which they say will only last 1-3 days (here's hoping!) but totally worth it if you ask me. I don't have any before/after pics but I definitely can see a difference. I've never been so happy with my teeth, lol. My dentist offered an amazing deal (only $99...originally $400) so I had to do it. So if you're on the fence about doing it I say go for it! I'll be doing a touch up with my dentist's whitening strips (stronger/more bleach than store bought) right before the wedding. I'm so happy I'll have a brighter smile for our wedding day!
