As someone who's used whitening strips in the past I am unable to use them full on for 20 consecutive days because of the sensitivity I get. Sensitivity in the teeth is completely normal when using whitening kits and sometimes worth it for faster results. But what's a girl to do? Use them non stop for 20 days and be tortured when the simple act of biting - say, a cookie makes you stop dead in your tracks? I think I'll pass. So instead I have been using these once a week. Yes once. So far so good and no sensitivity. These strips are worth it, especially if you're a poor gal like me.Can't wait to rock pearly whites at their max!
