I understand the bleach category shade guide starting at BL1, BL2, BL3, BL4. That being said these are obviously very white teeth in my opinion. My question is considering the bleach category, do you think the B1 is a more natural looking shade compared to the bleach ones, or do you still consider it on the too white side for a natural looking teeth. Is the B1 in your opinion a good choice for someone who wants a white but natural looking teeth?
