It’s June, which means it’s time for my annual round of Crest Whitestrips. Well, they are hurting my bottom row of teeth. Pain starts 2-3 minutes after I put a strip on, stops as soon as I take it off. I guess it’s a gum thing (I have never had a cavity… what do they feel like?) It makes sense that it would be a gum thing, because I’ve just been on a very stressful trip, and in the past, stress has made them inflamed.
But none of this is my question (hooray! no medical disclaimers needed!) What I want to know is: if I discontinue the strips for a week or so, then start them again, will I end up with the same whitening in the end? Is there something about them that makes them work better when used twice a day for seven days, as directed? Or is it all strictly cumulative?
