Brushing the teeth doesn't mean that it is going to make white, it is going to clean the teeth surface of plaque and tartar and keep your mouth and teeth germ free
It s advised to get your teeth cleaned every 6months by your dentist and they even polish your teeth with special paste that will glitter your teeth
for yellowness it is the dentine shade of tooth the second layer of tooth which often gets highleted from white of enamel so for some patient it looks yellow
some times dentist evaluates and suggest teeth beaching that will result one or 2 shades lighter of your shade but this is not recommended for all as it may lead to dentinal hypersensitivity
