Understanding Tooth Changing Color: Causes and Solutions

tooth changing color

Have you ever noticed that your teeth aren’t as white as they used to be? Are you wondering what causes teeth to change color? Tooth changing color is a common problem that can be caused by a variety of factors.

Tooth discoloration can be caused by lifestyle habits, such as smoking, drinking coffee or tea, and poor oral hygiene. It can also be caused by medical conditions, certain medications, and even aging. Understanding the causes of tooth changing color can help you determine the best course of action to keep your teeth looking bright and healthy.

Food & Beverages That Stain Teeth

Have you ever noticed that certain foods and drinks can leave your teeth looking stained or discolored? Well, it’s because they contain chromogens, which are highly pigmented molecules that latch onto tooth enamel. This can result in tooth changing color, making them appear yellowish or brownish after a while.

Tea and Coffee:

Tea and coffee are two of the biggest culprits when it comes to tooth discoloration. Both these drinks contain tannins, which cause dyes to stick to your teeth more easily, leading to tooth changing color. If you can’t do without your morning cup of coffee, try drinking it quickly and rinsing your mouth with water afterwards.

Red Wine:

Red wine is an alcoholic beverage that’s infamous for staining teeth. Not only do tannins cause the discoloration, but a natural acid in the wine can also erode tooth enamel, leaving your teeth more vulnerable to stains. Sipping on water between sips of red wine can help minimize the damage and prevent tooth changing color.


Carbonated drinks such as soda can also change the color of your teeth. They contain acids that wear away at tooth enamel and can lead to tooth changing color, resulting in yellowing of the teeth. It’s best to avoid soda altogether, but if you must drink it, use a straw so that it doesn’t come into direct contact with your teeth, preventing tooth changing color.

The Use of Tobacco Products and Tooth Discoloration

Not only is smoking and tobacco use detrimental to our overall health, but it can also lead to tooth changing color due to the tar and nicotine that are present in tobacco products.

Yellow or Brown Teeth:

Smoking causes a yellowish or brownish discoloration on your teeth due to the chemicals in tobacco. Over time, this discoloration can worsen and form stubborn stains on the teeth, which can be difficult to remove. People who chew tobacco can experience similar discoloration of their teeth and gums, as well as bad breath and poor oral hygiene.

How to Reduce the Damage:

The best way to prevent tobacco-related tooth discoloration is to quit smoking or using tobacco products altogether. However, if you’re not ready to quit, there are steps you can take to minimize the damage to your teeth:


  • Brush your teeth regularly with a whitening toothpaste
  • Visit your dentist in Tijuana for regular cleanings
  • Avoid drink and food that stain your teeth, including coffee and red wine
  • Use a straw when you drink soda or other sugary drinks


By taking these steps, you can reduce the damage that tobacco and other staining substances can do to your teeth, and maintain a brighter, healthier smile.

Trauma and Injury to Teeth

Accidents happen and unfortunately, teeth may be affected by trauma or injury. Any physical force that hits or damages a tooth can potentially disturb the inner layer called dentin, which affects tooth color. Dentin is normally yellow but when it gets exposed, it can change the whole tooth color. The severity of the injury may also affect how much tooth changing color occurs.

Treatment options

If you suffer an injury to your tooth, it’s important to seek dental care right away. Treatment options may vary depending on the severity of the injury. If there is only minimal damage, then teeth whitening can help restore the tooth’s natural color, preventing tooth changing color. If the injury is more severe, then the dentist may use bonding, veneers, or a crown to cover the discolored tooth, preventing tooth changing color.

The Impact of Medications on Tooth Color

Medications can also be the culprit behind tooth changing color. Certain antibiotics, such as tetracycline, can cause permanent stains on teeth when administered during childhood when the teeth are still developing, resulting in tooth changing color. Other medications such as antipsychotics, antihistamines, and blood pressure medications can cause discoloration as well, leading to tooth changing color.

Preventive measures

If you’re taking medication that can potentially cause tooth changing color, there are things you can do to minimize its effects. Brushing regularly and scheduling regular dental cleanings can help remove surface stains and prevent tooth changing color. Drinking through a straw can also reduce contact between the medication and your teeth, minimizing tooth changing color. After you’ve finished taking medication, teeth whitening treatments may help restore your teeth’s natural color, preventing tooth changing color.

Treatment options

If the tooth changing color is severe, then the best option is often dental veneers or crowns. Veneers are thin, tooth-colored shells that cover the front surface of teeth, preventing tooth changing color. A crown, on the other hand, is a cap that completely covers the tooth, preventing tooth changing color. Both options can effectively cover discolorations and provide a natural-looking appearance, preventing tooth changing color.

Genetics and Discolored Teeth

It’s a fact that genetics can influence tooth changing color. Some people are simply more prone to discoloration, and it can be as simple as the color of enamel. Enamel is the thin outermost layer of the tooth that gives it its color, and some people are just born with thicker or thinner enamel. Thicker enamel is naturally more white, while thinner enamel can appear more yellow or gray, resulting in tooth changing color.

Additionally, genetics can also play a role in how well our teeth resist staining. Certain genetic mutations can result in weaker enamel that is more porous and prone to staining. This can lead to discoloration caused by everyday habits such as drinking coffee or tea.

Prevention and Treatment

If you have tooth changing color that is caused by genetics, you may feel like there’s not much you can do to prevent or treat it. However, there are some steps that you can take to minimize the effects. Regular brushing, flossing, and dental visits are all important in maintaining healthy teeth and preventing staining from setting in, preventing tooth changing color. Additionally, if your tooth changing color is severe, your dentist may recommend professional whitening treatments or other dental procedures, addressing tooth changing color.

Age and Tooth Discoloration

As we age, our teeth naturally undergo tooth changing color. This is due to a combination of factors, including years of exposure to staining foods and beverages, as well as the natural wear and tear on tooth enamel. Additionally, as we get older, the inner layer of our teeth, called dentin, can start to yellow or darken, further contributing to discoloration and tooth changing color.

Slowing Down the Process

While we can’t stop the aging process, there are steps we can take to slow down the tooth changing color of our teeth as we get older. For example, frequent brushing and flossing can help remove surface stains before they have a chance to set in, preventing tooth changing color. Additionally, cutting back on staining drinks such as coffee or red wine can also help prevent discoloration, reducing tooth changing color.

Poor Oral Hygiene and Discolored Teeth

It’s no secret that poor oral hygiene can contribute to tooth changing color and a number of dental issues. Inadequate brushing and flossing habits can allow plaque and tartar to build up on the teeth, resulting in yellow or brown staining, leading to tooth changing color. Additionally, poor oral hygiene can contribute to gum disease, which can cause the gums to recede and expose the roots of the teeth. This exposure can also cause tooth changing color, as the roots are not covered by the same protective enamel as the rest of the tooth.

Potential Remedies for Poor Oral Hygiene and Tooth Changing Color

The good news is that tooth changing color caused by poor oral hygiene can often be improved with better dental habits. Regular brushing and flossing, as well as routine dental cleanings, can help remove surface stains and prevent further tooth changing color. In more severe cases, a dentist may recommend professional teeth whitening treatments to remove deeper stains and restore a brighter smile, addressing tooth changing color caused by poor oral hygiene.

Fluoride and Tooth Color

While fluoride is an important mineral for dental health, overexposure to fluoride can lead to tooth changing color. This condition is known as fluorosis and typically presents as white or brown spots on the teeth. Fluorosis is most commonly caused by excessive fluoride intake during childhood, often from drinking water that has been treated with high levels of fluoride, resulting in tooth changing color.

Preventative Measures for Fluoride-Induced Tooth Discoloration

To prevent fluorosis and tooth changing color, it’s important to be aware of the fluoride content in your drinking water and adjust your intake accordingly. Some areas have naturally high levels of fluoride in the water, while others add fluoride to their water supply to promote dental health. If you live in an area with naturally high fluoride levels, consider switching to bottled or filtered water to prevent tooth changing color. Additionally, parents should monitor their children’s fluoride intake, ensuring that they only use a small amount of fluoride toothpaste and don’t swallow it, preventing tooth changing color.

Understanding the causes of tooth changing color can help you take steps to prevent and treat this common dental issue. By maintaining good oral hygiene habits and being mindful of your fluoride intake, you can keep your teeth looking bright and healthy, preventing tooth changing color, for years to come.

Medical Conditions and Tooth Discoloration

Believe it or not, your dental health could be an indicator of your overall health, and certain medical conditions can contribute to tooth changing color. For instance, diabetes not only affects your blood sugar levels but can also cause gum disease and tooth decay, resulting in tooth changing color. High blood sugar levels can cause a buildup of plaque, leading to teeth turning yellow or brown, causing tooth changing color.

How Diabetes Affects Teeth

Diabetes affects teeth by reducing the flow of saliva in your mouth. Saliva helps neutralize the bacteria in your mouth, but the lack of it can lead to a buildup of bacteria, resulting in tooth decay and discoloration, contributing to tooth changing color. Furthermore, people with diabetes are more prone to infections, which can have negative effects on gum health, further impacting tooth changing color.

Liver disease is another medical condition that can contribute to tooth discoloration. Liver disease can cause a yellowing of the eyes and skin, a condition known as jaundice, which can also affect teeth, resulting in tooth changing color.

How Liver Disease Affects Teeth

The liver is responsible for producing bile, which helps break down fats in the body. However, when the liver is not functioning properly, bile can build up in the body, leading to jaundice and tooth discoloration, contributing to tooth changing color. Furthermore, liver disease can cause a dry mouth, increasing the risk of tooth decay and discoloration, further impacting tooth changing color.

Environmental Factors That Affect Teeth

In addition to medical conditions, environmental factors can also contribute to tooth changing color. Exposure to pollution and chemicals can have a negative impact on dental health, leading to tooth changing color.

Pollution and Tooth Discoloration

Pollution can result in a buildup of toxins in the body, affecting teeth. For instance, exposure to air pollution can cause teeth to turn yellow, contributing to tooth changing color. Furthermore, certain heavy metals found in polluted environments can also contribute to tooth discoloration, causing tooth changing color.

Chemicals and Tooth Discoloration

Chemicals found in certain foods, drinks, and even toothpaste can also contribute to tooth changing color. For example, coffee and red wine can stain teeth, as can tobacco use, leading to tooth changing color. Furthermore, fluoride, a common ingredient in toothpaste and drinking water, can cause discoloration in high doses, resulting in tooth changing color.

Pregnancy and Tooth Discoloration

Many women experience changes in their oral health during pregnancy, and tooth changing color is one of them. Hormonal changes that occur during pregnancy can affect the body in various ways, including the teeth. Pregnant women may notice their teeth appearing darker or yellowish in color, contributing to tooth changing color.

This is due to the increased levels of estrogen and progesterone in the body, which can impact the blood supply to the teeth and gums. These hormonal changes can also cause alterations in the texture and composition of the teeth, making them more prone to stains and discoloration, resulting in tooth changing color.


While tooth changing color during pregnancy is common, preventive measures can be taken to minimize its occurrence. Maintaining good oral hygiene, such as regular brushing and flossing, can help keep the teeth healthy and prevent staining. Pregnant women should also avoid foods and drinks that are known to cause tooth discoloration, such as coffee and red wine, thus reducing the risk of tooth changing color.


If tooth changing color does occur during pregnancy, there are treatment options available. However, it is crucial to consult with a dentist before undergoing any treatment while pregnant. We may recommend professional teeth whitening treatments or veneers to enhance the appearance of discolored teeth affected by tooth changing color.

Teeth Whitening Options

If you’re looking to whiten your teeth, there are several options to choose from. From over-the-counter products to professional treatments, each option has its own set of pros and cons.

Over-the-Counter Products

Over-the-counter whitening products, such as whitening toothpaste, strips, and gels, are readily available at most drugstores. While they are typically less expensive than professional treatments, they may not be as effective and can take longer to achieve noticeable results. It is also important to follow the instructions carefully to avoid any damage to the teeth or gums.

Professional Treatments

Professional whitening treatments, such as laser treatments and bleaching, are typically more expensive than over-the-counter products but can provide more dramatic results in a shorter amount of time. It is important to consult with a dentist before undergoing any professional treatment to ensure that it is safe and effective for your specific situation.

Ultimately, the best teeth whitening option depends on your individual needs and budget. It is important to weigh the pros and cons of each option and consult with a dental professional to determine the most appropriate treatment for you.
