Why do people`s teeth remain dirty?


Answers
Candace w.
Because they do not clean their teeth and they become dirty and stain
Suru
Because they don't use good Datun stick but only toothpastes and eat chocolates too.
Editor
Definitely the human teeth need not remain dirty, on its own it won’t get cleaned. Basically they get dirty because of the job they do, chewing food for you. Part of the food sticks to the teeth, the food sits there and decays, bacteria thrive on this food and the teeth get dirty. Clean them properly with brush and also massage with your fingers to keep them clean and healthy. Good oral health is very important to general health as well.
Sarthak Shashi Agarwal
Nowadays people think it is boring to brush and don't, so they remain dirty and stink
hannah Kemp
Well when you don't brush your teeth the bacteria starts to eat away and strip or sink into your teeth then when you finally try to clean them they are stained similar to when you colour your hair it never returns to the exact colour because it stains. Thats why teeth are yellow cause it is decay and bacterial.
ankita
Because after eating the food our remaining food particles get stuck into our tooth and if you are not brushing the teeth the bacteria may attack the tooth and can ruin the teeth which make the tooth fall and make them dirty.
