2) Age

Teeth ultimately turn yellow as one grows older. The enamel wears away from chewing and exposure to acids from food and drink. Teeth turn yellow as the enamel thins with age and the dentin below the enamel gets exposed.

3) Smoking

Nicotine from smoking causes teeth to become yellow and brown due to the stains from it. With a prolonged smoking habit, teeth gradually change colour. It's important to quit smoking if you wish to have whiter teeth.

4) Drinks

Alcohol, tea, and coffee contain substances which cause stains on your teeth and yellowing. These substances must be avoided or you can drink using a straw to prevent exposure to teeth.

5) Fluorosis

Fluoride is important for healthy teeth. But, excessive fluoride may cause yellow or brownish  teeth leading to fluorosis. Fluoridated water, fluoride toothpaste or fluoride tablets may be possible sources of fluoride. You can consult your dentist on how to reduce the fluoride content in your diet.

6) Accidents

Accidents may cause wearing of the enamel and exposure of dentin thus leading to yellow teeth. Physical abrasion must be treated with a dentist's help and treated immediately.

Although yellow teeth are not as urgent a problem as other dental problems, nevertheless they may cause you to become less confident and conscious of your appearance.
