There are a few reasons why teeth become discolored:

1. Consumption of staining drinks such as colas, coffee, tea, and red wine are among the most common-as is smoking (tobacco), of course.

2. Other factors such as nerve degeneration, the use of antibiotics or excessive fluoride (especially during young development), and dental traumas also darken teeth.

3. Discoloration may also be an effect of aging - so stop that RIGHT NOW!
