Question: are you supposed to brush your teeth after crest 3d white strips?
Answer: Yes, Crest 3D Whitestrips do not harm tooth enamel and are safe to use, so you can use one pack right after another. ... You can brush your teeth gently immediately after using Whitestrips, but we do not recommend brushing your teeth immediately before applying Whitestrips, because this may irritate your gums.
