Your teeth are covered with a white layer called enamel. (duh)  When the enamel fades, it exposes the yellow dentin below the enamel.  Here are some surprising things that causes your teeth to yellow.Your Toothbrush Is Too Hard. If you use a toothbrush with hard bristles, this can wear away the enamel.  So can brushing too hard.  Use soft bristles and a soft touch.

Skin Complexion.  If you are light-skinned, your skin color can make your teeth look yellower. The darker the complexion, the whiter the teeth look.

Medication.  There are medications that can cause your teeth to stain. Some acne medications, blood pressure medications, and anithistamines can cause teeth staining.

Swimming.  The chemicals in the pool water can cause your teeth to yellow. It's because the chemicals in the water can cause deposits to build up on the teeth.

Not Drinking Enough Water.  Drinking water is good for you. But did you know that if you don't drink enough water, your teeth could yellow?  Drinking water after consuming foods or drinks that can stain teeth can help reduce yellowing.
