Answer:
It seems like everyone is trying to get their teeth whiter. Teeth whitening agents are often the main ingredient in toothpaste (which doesn’t seem to really work), dental floss, mouthwash, whitening strips, gels, and even chewing gum.
Yellow teeth, on the other hand, seem to be a bad thing and are often associated with poor oral hygiene. Luckily, we have some good news for those who don’t have pearly whites. Yellow teeth are actually healthier than white teeth!
