Is it normal my teeth are like this
So basically, no matter how many times I've brushed my teeth they are still slightly yellow. I brush my teeth at the most 4-5 times a day. (After every meal) And I don't just brush them that much to whiten them, I do it that much to get the dirt off of them. But I'm wondering why are they still yellow no matter how much I brush them. After I brush them they are smooth and shiny but a Disguising yellowish colour. I would say they are half yellow and half white mixed together. Why are my teeth yellow ? And most peoples white? I've brushed them all my life and always looked after them!!!
Ps. I use mouthwash (listerine zero to be specific)
