Your teeth has an outer layer known as the enamel. The color of your teeth comes from the scattering and reflection of light off the enamel, and the color of your dentin. The smoothness and thickness of your enamel is determined by your genes. If you have a thin enamel, the color of the dentin will show more through it. A rough or smooth enamel affects light reflection and by extension the color of the enamel.
A pellicle forms on your enamel on a daily basis. This pellicle collects stains. Your enamel contains pores that can trap stains.
The major reasons why the teeth gets stained include:
- Smoking tobacco products
- Poor dental hygiene
- Taking liquids with dark color such as cola, coffee, red wine, and tea.
Aging also affects the color of the teeth as the enamel thins and the dentin darkens.
A person may also have stains within the tooth. Stains that occur inside a person’s tooth are known as intrinsic stains. In children, they may be caused by over-exposure to fluoride. Tetracycline antibiotics are also a common cause of intrinsic stains.
