i brush my teeth every morning , afternoon and night but teeth still yellow , how to make it whiter?

Crest white strips. The clinical strength are best. Also, make a paste of baking soda and peroxide and brush with it and then put some on a wash cloth and scrub the problem areas. Do that each day and then rinse
Use a whitening toothpaste. Uh, cut out any soda, coffee or tea (Or at least cut BACK if you drink a lot of those).
if they won't get white with ordinary brushing then they are stained, you need to make an appointment at the dentist for teeth whitening.
A little yellow color of teeth is good.. It means you have strong teeth.. Otherwise you could consult dentist.

Don't swallow toothpaste it makes them yellow.
A tin of Dulux should do it :P
