Teeth form a layer called plaque everyday and this needs to be removed by brushing. Sometimes when we are unable to remove plaque in certain areas it gets calcified and becomes hard yellow deposits on teeth...known as calculus.These deposits now cannot be brushed away but need a dental procedure called scaling. Once it is done you can continue to maintain until it gets built up again after 6 months to a year. If u don't have deposits but just minor staining due to tea or coffee u can try baking soda or rubbing a banana peel. Doing this on a regular basis may cause sensitivity.
