Our teeth have a topmost layer called enamel which is thin and whitish in color. The second layer is dentin which is comparatively thicker and yellowish in color.

Tooth stains also termed as tooth discoloration is abnormal tooth color. Your teeth can become discolored by stains on the surface or by changes inside the tooth.

The stains can occur either on the surface of the tooth or when the inner structure of the tooth darkens. The stains that occur on the surface of the tooth are called extrinsic stains teeth. The stains that occur due to the inner layer of the tooth getting darkened are the intrinsic stains. Age-related staining is a combination of extrinsic and intrinsic factors. Dentin naturally yellows over time. The enamel that covers the teeth gets thinner with age, which allows the dentin to show through.
