BonAiyu Teeth Whitening Strips consist of activated charcoal that helps in removing yellow stains from the teeth. The pores in the activated charcoal bind with the rough parts of teeth that generally capture plaque and stains, making it easier to get rid of yellowness. The minerals present in the charcoal take away the plaque, food particles, and germs with them when the charcoal strip is removed.
