Teeth whitening has been going on for thousands of years. Back in Ancient Egypt, people used to use wine vinegar and ground pumice stone just to create a paste that would whiten their teeth. 

Even the Ancient Romans use something to whiten their teeth. Unfortunately, their main ingredient is a little bit disgusting. Ammonia, which is found in urine, acts as a whitening agent.
