Major Causes of Teeth Discoloration—What to Know & Avoid

Categories: Dental News

There is nothing more aesthetically pleasing than having a complete set of pearly white teeth. Not only will it give you a perfect smile, but it will also boost your overall confidence. However, it’s easy to see most people, especially older individuals, with yellowish teeth or even stained ones. For the most part, people typically attribute teeth staining to the inevitable signs of aging. However, did you know that foods and beverages and other factors can even contribute to teeth staining?


In this article, we will share the major causes of teeth discolouration and what you must do and avoid:



Let’s first take a look at some common drinks that can stain your teeth, such as the following:

  • White and red wine: They are particularly notable for discolouring your teeth. As you may or may not be aware, they contain acids that can impair the teeth’s enamel. While red wine can be the biggest culprit for teeth stains, white wine can cause more damages due to its acid content.
  • Tea and coffee: They both have long been known to cause teeth discolouration due to their staining properties. Same with wine, coffee contains acids that will damage your teeth. When it comes to teas, on the other hand, the black one is the most impactful as herbal, white, and green teas have less staining effects.
  • Soft drinks: They have a very damaging effect on the teeth, as they are rich in chromogens and acids. They are also full of sugar that can be detrimental to your overall oral health, which is why you must avoid them.



Now that you know several harmful drinks for your teeth, let’s now delve into some foods that can also cause staining:

  • Berries: As they are abundant in colour, they can cause teeth staining. With that being said, be sure to avoid blueberries, cranberries, blackberries, grapes, cherries, and pomegranates.
  • Sweets: Of course, they are delicious and can fill your tummy, but they aren’t recommended for your oral health. Not only do they stain your teeth, but they also lead to dental cavities and destroy your teeth. Be sure to avoid hard candies, popsicles, chewing gum, and similar sweets. 


Other factors

As mentioned, other factors can lead to tooth discolouration as well, such as the following:

  • Tobacco: Smoking has long been proven to stain teeth. Not only is it harmful to your oral health but to your overall health as well. Tobacco can be the most detrimental in staining your teeth.
  • Advancing age and genetics: As pointed out previously, aging is one of the biggest culprits of teeth discolouration. As you get older, the enamel gets worn away and starts revealing the dentin underneath. Also, genetics can play an important role, which is why you see some people with naturally white teeth while some have yellowish teeth.
  • Poor dental hygiene: Having good dental hygiene also makes a difference in protecting your teeth and washing out the stains. For this reason, be sure to brush your teeth twice a day or after every meal. Likewise, don’t forget to visit your dentist regularly—every six months will do!



At this point, you now know the common causes of teeth discolouration—foods, drinks, and other factors. Be sure to avoid consuming those mentioned above or do so in moderation, and have proper oral care by brushing and flossing your teeth twice daily. Also, make it a habit to visit your dentist at least every six months for a dental checkup and cleaning. Ultimately, undergo teeth whitening treatments if you truly want to have a sparkling, bright, and pearly white smile!
