Don't run away! I just want to discuss the reason for the yellowish tinge on your teeth.

Once and for all, let’s be clear about why and how teeth get stained. Just as your body is protected by a soft skin, teeth are protected with something called enamel which is harder than bone.

Whatever goes through your mouth — food, drinks, smoke — accumulates and forms a pellicle film that coats the enamel of your teeth. It is this pellicle film that gives your teeth the yellowish tinge.

So the next time be careful about what you eat and drink. And make sure that you clean your teeth properly.
