Do crest white strips remove permanent stains?
It will help lessen the color, since your teeth aren’t very yellow, then using strips may get you back to a white. When you buy them, buy 2 or 3 packs because they only last a few weeks. For best results you want them for months. I recommend Listerine whitening strips. I had a really yellow tooth that stood out in pictures of e smiling. I used them for 3 weeks and I noticed the tooth blended in more with my teeth. No it won’t cause discoloration. The worst thing is probably burning gums or some kind of allergy.
