Yellow teeth stains can actually cause an abnormal teeth color. This can cause poor smile by making some people feel very self-conscious about the looks of their teeth. Teeth discoloration usually happens slowly and it’s easy to overlook teeth going yellow. Moreover, it’s natural for people’s teeth to become less white as they grow older, so having yellow teeth isn’t a sign that something is seriously wrong.
However, having a clear understanding on why the color of your teeth is turning yellow can help you to prevent further discoloration and damages. Generally, the causes of tooth discoloration are divided into three different categories – extrinsic, intrinsic and age-related discoloration.
- Extrinsic stains. Teeth enamel is the hard, outermost layer of teeth. When the enamel is not taking proper care of, it can easily wear down or discolor. Extrinsic stains usually occurs when the outer layer of the tooth (enamel) is stained. Coffee, wine, cola, chocolate and dark sauces are some of the common causes of this type of stains. Luckily, these stains can be easily removed or corrected.
- Intrinsic stains. This stains occur within the inner structure of the tooth (the dentin). Unlike extrinsic stains, intrinsic stains occur in the inner part the tooth making it very difficult to be removed. A child’s teeth is likely to turn brownish yellow if the child takes the antibiotics tetracycline or doxycycline while his or her teeth are still developing (before the age of 8). Also, if your mother used tetracycline antibiotics during the second half of pregnancy, you can have yellow teeth stains.
- Age-related stains. Naturally, the dentin is yellow in color and it’s found right below the enamel. As you get older, the outer layer of enamel thins over time, making teeth appear more yellow as it allows the dentin to show through. Some abrasive food, chips or other dental injuries can discolor a tooth, especially when the pulp has been destroyed.
Causes of yellow teeth stains
1. Tooth erosion. The dentin which is a yellow or brownish-colored material hidden right under the enamel, is one of the main reasons that teeth look yellow. Although our teeth enamel are strong, but they can wear away with long exposure to the acids in the foods and drinks you take. Check here to – learn more about tooth erosion.
2. Genetics. Many people fail to know that their genetic make-up plays a significant role in the brightness and thickness of their enamel. Some people are born with thicker, whiter enamel that can withstand erosion while others are not. There are times when yellow teeth just run in a family because of the nature of their enamel.
3. Medications. During adulthood, a number of medications such as antihistamines, antidepressants, antipsychotic drugs, and drugs used to manage high blood pressure. can cause intrinsic yellow teeth stains. In addition, children who are 8 years old or younger have tooth discoloration after taking certain antibiotics like tetracycline or doxycycline while their teeth are still developing. Sometimes, the use of mouthwashes that contains chlorhexidine or cetylpyridinium chloride can cause tooth stains in both adults and children.
4. Smoking and Tobacco use. The chemicals and nicotine in tobacco products can cause extrinsic yellowish stains on the surface of teeth. In mild cases, these type of stains are easily removed with proper cleaning. It’s is also very important to know that chewing or smoking tobacco can equally put you at a higher risk of gum disease and other oral health problems.
5. Foods and drinks. Many foods and drinks out there contains lots of teeth-staining pigments that can cling to your teeth enamel and stain them. Dark-colored foods and beverages, including red wine, colas, chocolate and dark sauces such as soy sauce, balsamic vinegar, spaghetti sauce and curries can actually lead to yellow teeth stains. In addition, some fruits and vegetables such as grapes, blueberries, cherries, beets and pomegranates have the potential to stain teeth. (1)
6. Fluorosis. Fluoride is beneficial to your oral health as it helps in strengthening the enamel and preventing decay. Well, too much of fluoride is not needed because it can cause a condition known as fluorosis which leaves the teeth brown or yellow.
7. Dental trauma. Accidents and physical dental trauma can crack off your tooth enamel and eventually lead to the discoloration of the affected tooth. This type of tooth discoloration can occur in both adults and children. But in most cases, it is most commonly seen in children especially when they are still learning how to work. On my previous post, I explained more on tooth discoloration after trauma. You can read the post here – treatments for tooth discoloration after trauma.
