Yellowish stains on the teeth can be both intrinsic or extrinsic...... in either case, if the stains have already developed, they cannot be removed by brushing alone.... you need to visit a dentist to find out the exact cause of these yellowish stains followed by the right treatment plan for the same.... education about the right brushing technique can also be obtained from your dentist....
