Teeth may turn dark for a number of reasons, including:
Romesh Nalliah, Dentistry, answeredTeeth darken for a variety of reasons. The first, and most important, is poor oral hygiene. Additionally, specific foods/drinks can accelerate stain formation between cleanings- the tanins from teas and wines are recognized for their stain forming ability. Also, medications taken during the formation of teeth (most notably tetracycline antibiotic) and dental trauma can lead to tooth discoloration.
Jerry Gordon, Dentistry, answeredTeeth darken by repeated use of staining foods and beverages. Some common culprits include red wine, dark sodas, coffee, tea, blueberries, and red beets. Cigarette and cigar smoking can also cause teeth to darken. Avoiding these beverages, foods and habits can prevent your teeth from discoloring. Dentists can also whiten teeth with a variety of treatment options.
