The tooth is made up of four different tissues. The enamel is the strong white covering that protects the tooth from wear and tear of chewing food. Dentin supports the enamel. It is a hard, yellow material that carries the nerves in your teeth. The pulp is the center of the tooth. It contains nerves, blood and lymph vessels. This part is where the tooth receives nourishment and transmits signals to the brain. The fourth part is called the cementum. This covers the root of the tooth. It attaches the teeth to the bones in your jaw.The key reason teeth turn the yellowish tint is that when people eat, drink, or smoke, a layer of film develops on the tooth

Our teeth turn yellow mainly due to the following reasons:

1.Tobacco smoking or chewing

2.Consistent and intentional ingestion of fluoride from toothpaste and/or mouthwash.

3.Supplements containing iron.

4.Dental materials, such as the color of restorative material that may show through the translucent appearance of the enamel.

5.Poor dental hygiene leading to the formation of tartar and plaque, which in turn makes it easier for stains to accumulate from foods, drinks or tobacco.

4.Consuming acidic food and drink, etc
