  Your teeth are in a constant battle against staining. The foods you eat, what you drink and your lifestyle all contribute to the health of your teeth. Acidic foods and beverages can especially take a toll on tooth enamel. Daily brushing and flossing will help maintain a healthy mouth between regular check-ups with your dentist.
  
  

Tobacco

• Smoking and chewing tobacco will cause teeth to yellow. Nicotine is the ingredient that leaves hard-to-remove stains on tooth enamel.
  
  

Foods

• Dark foods are able to stain teeth. Think berries, soy sauce, and balsamic vinegar. Light colored foods can also yellow teeth such as apples and potatoes. Anything that has food-coloring is also a culprit.
  
  

Drinks

• The classic culprits of teeth staining drinks are coffee, tea, sodas and wine. Any dark juice is capable of staining, too. Follow a teeth-staining beverage with a glass of water to help rinse out the mouth if you are unable to brush right away.
  
  

Aging

• It is an unfortunate fact that your tooth enamel wears off as you age. This causes a discoloration, making your teeth less than perfectly white. If you were dealt good genes, you may have less discoloration than others.
  
  

Physical Trauma and Disease

• Teeth may turn yellow or discolor if they have been traumatized, cracked or broken. Yellowed teeth may be a symptom of disease as well as certain radiation treatments.
  
  

Hygiene

• Teeth naturally build up plaque throughout the day as you eat and drink. The bacteria in your mouth create the plaque and can lead to tartar build-up if plaque is not removed through routine brushing and flossing.
