Are yellow teeth healthy? In general, the answer to this question is yes; teeth are naturally slightly yellow in colour. Even if your teeth are a little more yellow than others, yellow teeth are typically healthy and do not affect the function or structural integrity of the tooth. However, in some cases, yellow teeth can be unhealthy and indicative of a more serious oral health problem such as periodontal disease. This article will provide information on why teeth turn yellow in the first place and explain when yellow teeth may be a sign of an underlying health condition. We will also discuss how to prevent yellow teeth and what treatments are available to restore a healthy, white smile.
What Usually Causes Yellow Teeth?
Yellow teeth can be broken down into two different types; intrinsic or extrinsic staining. Typically, these types of staining are a result of non-harmful causes such as medications, foods and beverages, or aging.
Intrinsic Staining
Intrinsic staining occurs when the stains penetrate deep beyond the surface of the enamel (the outermost layer of your teeth) and cannot be removed mechanically through brushing. Intrinsic staining is typically caused by foods and drinks such as coffee, red wine, and tea. Other causes of intrinsic staining include smoking, certain medications, aging, and genetics. These types of stains can only be removed through the use of a bleaching agent, such as hydrogen peroxide, which oxidizes the stains and reverses the yellowing.
The use of hydrogen peroxide for teeth whitening has been extensively studied and has been found to be both safe and effective. In a study published in the Journal of the American Dental Association, researchers compared the effects of hydrogen peroxide and carbamide peroxide, another common bleaching agent, on the enamel and dentin of extracted teeth. The results showed that both agents were able to effectively whiten the teeth, with no significant differences in the degree of whitening or the amount of enamel or dentin loss.
This means that intrinsic staining, which can cause teeth to turn yellow, is usually healthy and reversible with the proper whitening products.
Extrinsic Staining
Extrinsic staining, on the other hand, occurs on the surface of the enamel and can be removed through mechanical brushing with whitening toothpaste.
Whitening toothpaste contains abrasives, such as hydrated silica or calcium carbonate, that physically remove the surface stains from the teeth. In a study published in the Journal of Clinical Dentistry, researchers compared the effects of different abrasive agents on the surface roughness and stain removal of extracted human teeth. The results showed that all of the abrasive agents were able to effectively remove the surface stains, with no significant differences in the amount of stain removal or the degree of surface roughness.
Once again, this means that most cases of extrinsic staining are healthy and easily reversible with the use of regular brushing and flossing of teeth.
When are Yellow Teeth Unhealthy?
Periodontal Disease
One example of when yellow teeth are unhealthy is when they are a result of periodontal disease, which is a serious bacterial infection that affects the gums and bones supporting the teeth.
Periodontal disease is caused by the accumulation of dental plaque, a sticky film of bacteria that forms on the teeth. The bacteria in plaque produce toxins that irritate the gums, causing them to become red, swollen, and bleed easily. If left untreated, the bacteria can spread and damage the supporting structures of the teeth, leading to tooth loss and other serious health complications.
One of the most common symptoms of periodontal disease is yellow tartar, which is a hard calcified deposit on the teeth that is formed from the accumulation of dental plaque and mineral salts in the saliva. Tartar can be yellow or brown in color, and can be seen as a thick layer on the teeth, especially around the gum line. Tartar is difficult to remove through brushing, and requires professional cleaning by a dentist or dental hygienist. In addition to yellow tartar, other symptoms of periodontal disease include bad breath, loose or shifting teeth, gums that are red, swollen, or tender, and a change in the fit of dentures or partial dentures.
If you notice any of these symptoms, it is important to see a dentist as soon as possible for a thorough examination and professional cleaning. In the early stages of periodontal disease, treatment may involve scaling and root planing, a procedure in which the dentist or dental hygienist removes the plaque and tartar from the teeth and smooths the root surfaces to prevent future accumulation of plaque. In more advanced stages, treatment may involve gum surgery to remove the infected tissue and repair the damage to the supporting structures of the teeth.
To prevent the development of periodontal disease, it is important to brush your teeth for at least two minutes twice a day with a soft toothbrush, floss daily, and visit the dentist regularly for professional cleaning and examination. In addition, avoid sugary and acidic foods and beverages, as these can contribute to the formation of dental plaque and tooth decay. By following these guidelines, you can maintain healthy, white teeth and avoid the potential health complications of periodontal disease.
A Result of Smoking/Vaping
Another example of when yellow teeth are unhealthy is when they are a result of smoking or vaping. The tar and nicotine in cigarettes and e-cigarettes can cause the teeth to become stained and discolored, usually starting at the gum line.
Smoking also increases your risk for developing periodontal disease, as it decreases blood flow to the gums, making them more vulnerable to infection and irritation. In addition, smoking is a risk factor for oral cancer and other types of cancers in the head and neck region.
Smoking (and vaping to some degree) have been shown to be bad for your overall health as well. This includes increasing your risk for developing heart disease, stroke, and other serious medical conditions.
If you smoke or vape and would like to improve the appearance of your teeth, quitting smoking is the best way to achieve this.
Too Much Flouride
Excessive fluoride intake can cause yellowing of the teeth. Fluoride is a mineral that is naturally present in water and is added to many dental products, such as toothpaste, mouthwashes, and gels, to help prevent tooth decay. While fluoride is beneficial for oral health in the right amounts (and can even help reverse cavities), excessive intake can lead to a condition called fluorosis, which can cause discoloration of the teeth.
Fluorosis typically occurs in children who are exposed to high levels of fluoride during the years when their permanent teeth are forming. The condition causes the teeth to become yellow, brown, or spotted, and can also lead to pitting and thinning of the enamel. Fluorosis can be mild, moderate, or severe, depending on the amount of fluoride exposure.
In addition to causing yellow teeth, fluorosis can also lead to other dental health problems, such as increased tooth sensitivity and decreased ability to fight off tooth decay. To prevent fluorosis, it is important to follow the recommended guidelines for fluoride intake. Children should only use a pea-sized amount of toothpaste containing fluoride, and adults should use a pea-sized amount of toothpaste containing fluoride twice a day. In addition, it is important to avoid using fluoride supplements without consulting a healthcare provider. By following these guidelines, you can help prevent the yellowing of teeth caused by excessive fluoride intake.
Conclusion
Are Yellow Teeth Healthy? The answer is yes – in most cases. It depends on the cause of the yellow discoloration. Generally speaking, if your yellow teeth are caused by genetics or are mild staining from food and beverages, this is usually nothing to worry about. However, if your yellow teeth are a result of smoking, improper brushing, or excessive fluoride intake, it is important to take steps to improve the appearance and health of your smile. Oral hygiene and regular dental check-ups can help you prevent cavities and tooth discoloration. Adopting healthy habits is the best way to maintain healthy white teeth. As always, it’s important to talk to your dentist about any concerns you may have about your oral health.
