How to whitening teeth at home?

Teeth whitening can be done at home with whitening strips, trays, and toothpastes. Peroxides like hydrogen peroxide and carbamide form effective whiteners by removing stains by foaming on them. A higher concentration makes for whiter teeth and quicker procedures. However they could get trapped in the nerve roots and cause increased sensitivity. This is remedied with brushing ones teeth with a gentle bristles toothbrush and using fluoride toothpaste.
