As people grow old the enamel on the teeth thins by wear and tear, which causes the inner yellow dentine layer to appear. Some people have whiter enamel due to genetics.

Over brushing with hard bristle toothbrush can cause quick wear and tear, causing the yellow dentine layer to show up. Dental materials like amalgam used for fillings can darken the color of enamel itself.

Do not over brush; use a soft bristle toothbrush to clean the teeth. Visit your dentist at least twice a year. Quit/cut on smoking and drinking wine. Consume drinking water that has less level of fluorides.
