EXTRINSIC STAINS
As noted in the preface of this article, stains that impact one’s tooth enamel are extrinsic stains. Lifestyle is one of the main contributors to this type of staining. For example, tobacco, wine, and coffee are notorious for causing discoloration. It is also worth noting that the foods and drinks that can stain clothes can also stain teeth as well, especially those that are dark in color like chocolate, balsamic vinegar, spaghetti sauces, and certain fruit juices, for example. The same applies to certain fruits and vegetables. While they may be a great source of nutrition, blueberries, pomegranates, and beets, for example, contain chromogens, which can bond to the enamel and cause discoloration. Also, some fruits and vegetables are naturally very acidic and can erode tooth enamel, which, in turn, makes it easier for teeth to become stained.
INTRINSIC STAINS
Intrinsic stains are more substantial than their extrinsic counterparts in that they occur in the tooth’s dentin, dense bone tissue that makes up nearly the entire tooth. In addition to poor oral hygiene, intrinsic stains can be the result of certain medications like antibiotics, for example. Intrinsic stains are usually brown or yellow and primarily affect the anterior teeth. These stains can also be caused by some prescription-strength mouthwashes like chlorhexidine gluconate, for example. While it is great a killing bacteria and reducing inflammation, long-term use can cause tooth discoloration. In addition to antibiotics and prescription-strength mouthwashes, antipsychotics, antihistamines, and high blood pressure medication are also known to cause discoloration. Another contributor to intrinsic stains is fluoride. Of course, this is not to say that one should avoid fluoride, but it is worth noting that excessive amounts can lead to fluorosis, brown spots that develop beneath the tooth’s surface.
HOW TO WHITEN YELLOW TEETH NATURALLY
Having detailed some of the causes of tooth discoloration, as well as the differences between intrinsic and extrinsic stains, let’s turn our attention toward prevention and treatment. To avoid tooth discoloration, it is a good idea to avoid smoking and also the foods and drinks that contribute to the problem in the first place. To further reduce the likelihood of teeth yellowing, you should practice good oral hygiene and be seen by a dentist at least once a year.
1. HYDROGEN PEROXIDE AND BAKING SODA
The combination of hydrogen peroxide and baking soda, when used as a paste, is almost comparable to professional whitening treatments in that it breaks up plaque and bacteria that can cause tooth stains. Most people who have used this hydrogen and peroxide to brighten their smiles noticed a significant improvement in as little as six weeks. The combination is so effective that many manufacturers have added it to several of their best-selling toothpaste brands. Here are a few tips to help get you started:
• Combine 1 tablespoon of baking soda and 2 tablespoons of hydrogen peroxide
• Mix the two ingredients until you formed a paste
• Brush for 2 to 3 minutes
As a side note, hydrogen peroxide and baking soda is also a great mouth wash. For best results, mix the same ratio of ingredients and rinse after brushing.
2. ACTIVATED CHARCOAL
Activated charcoal is also great at removing stains, bacteria, and toxins that typically lead to yellow teeth. Activated charcoal can be found in most pharmacies and big-box stores. However, it may not work for everyone, especially those with sensitive tooth sensitivity as the charcoal may be too abrasive. Nonetheless, if you are interested in trying activated charcoal, here are a few helpful tips:
• Place a toothpaste-sized amount of activated charcoal on a toothbrush.
• Gently brush in a circular motion for a minimum of 2 minutes.
• While this is optional, consider mixing activated charcoal with water as the combination can be used as a mouth rinse.
3. APPLE CIDER VINEGAR
Apple cider vinegar is also an effective way of resolving tooth discoloration. To whiten yellow teeth with apple cider vinegar, it is a good idea to use it as a mouth rinse before brushing. For best results, dilute 2 teaspoons of apple cider vinegar in 5 ounces of water and vigorously swish the liquid in your mouth for 20 to 30 seconds. The reason why apple cider vinegar is so effective is that it contains natural bleaching agents that work to breakdown stains caused by coffee, wine, and tobacco products.
4. COCONUT OIL PULLING
Coconut oil pulling is an effective way to remove plaque, tartar, and bacteria from the oral cavity. It has also been shown to be effective in reducing gingivitis as well. For best results, swish 1 or 2 teaspoons of coconut oil in your mouth for a minimum of 10 minutes before brushing. For those who are not a fan of coconut oil, sesame oil and sunflower oil are just as effective.
5. CONSUME WATER-BASED FRUITS
Eating fruits that contain a high percentage of water like oranges, grapes, and watermelon, for example, can help wash away plaque, food particles, and bacteria that often lead to yellowing and other types of discoloration.
6. FRUIT PEELS
Although it may sound peculiar, fruit peels derived from lemons, oranges, or bananas can help brighten your smile. The peels from these fruits contain d-limonene, which is a compound used to treat a number of health problems like cancer and bronchitis, for example. However, fruit peels are also used to whiten discolored or yellow teeth. Similar to hydrogen peroxide and baking soda, many manufacturers have added d-limonene to many toothpaste brands. For best results, rub a fruit peel on your teeth for a minimum of 2 minutes. After you’re done, however, make sure to rinse your mouth out thoroughly with water as the acid from fruit peels can erode tooth enamel, which, in effect, resolves one problem and creates another one.
