if you think it is a decay that has started in your teeth i would like you to go to your nearby dentist and get it confirmed. if it is decay then your dentist might suggest you to get some dental fillings done. if it is just stains that you are noticing then the stains could be removed by dental scaling that is cleaning. decay can be formed due to lots of food impaction in the back tooth regions which is a very common complaint. sometimes even though we are good in brushing there are areas where the brush cannot reach. for further information consult a dentist online --> <link>
