Tea is a beloved beverage around the world due to its various health benefits and comforting taste. Many of us love to have a hot cup of tea to start our day or to unwind after a long day. However, a common concern among tea drinkers is whether or not tea stains your teeth. The issue of tooth staining by tea has been a topic of discussion among dental professionals and tea enthusiasts for years. While some people believe that tea is a culprit for tooth staining, some argue that tea does not have the same amount of staining power as coffee or other beverages. In this article, we will delve into the world of tea, explore the science behind the staining, and provide you with the answers to the question: Does tea really stain your teeth?

What Causes Teeth Staining?

Teeth staining is a common dental problem that affects many people, and it occurs when the enamel of the teeth becomes discolored or yellowish in appearance. There are many factors that can cause teeth staining, and some of them include lifestyle habits, food and drinks consumption, and underlying medical conditions.


Smoking is one of the leading causes of teeth staining. The nicotine present in tobacco products can penetrate deep into the pores of your enamel causing yellowing to develop over time. Additionally, smoking also causes bad breath and increases your risk for gum disease.

Food and Drinks

Certain foods such as berries, curries and tomato sauce contain pigments that are known to stain teeth while others like sugary snacks increase plaque buildup leading to cavities. Drinking dark-colored beverages like tea, coffee or red wine also contribute significantly to tooth discoloration as they contain tannins which stick to teeth surfaces.

Poor Oral Hygiene

Poor oral hygiene practices such as irregular brushing or flossing allow bacteria to build up on your teeth’s surface making them more susceptible to stains caused by food particles getting trapped within cracks or crevices between tooth surfaces.


As we age our enamel thins out naturally exposing more dentin – a yellowish layer under our enamel- thus making our smiles appear less white than before.


Certain medications such as antibiotics given during childhood may cause intrinsic (internal) discoloration leading to greyish or brownish stains on adult teeth.

How Does Tea Contribute to Teeth Staining?

Tea is one of the most popular beverages in the world, and many people enjoy a cup or two every day. However, regular tea consumption can lead to tooth discoloration due to its high tannin content. Tannins are natural compounds found in tea leaves that give it its characteristic color and taste. In this section, we will explore how exactly tea contributes to teeth staining.

Tea consumption can contribute to tooth discoloration due to its high tannin content and acidic pH level. To prevent staining, it is recommended to use a straw, rinse your mouth after drinking, brush and floss regularly, use whitening toothpaste, and get professional teeth cleanings. If your teeth are already stained, over-the-counter whitening products, professional in-office treatments, and custom-made trays are effective options. However, natural remedies have not been scientifically proven and may cause side effects. Consult with your dentist for the most effective and safe teeth whitening option.


Tannins are a class of polyphenols that are present in many plants including tea leaves. These compounds bind with proteins on the surface of your enamel creating a yellowish-brown stain over time making your teeth appear darker or discolored.

High Acidic Content

Tea has an acidic pH level which can weaken the enamel by wearing away tooth minerals leading to further accumulation of plaque and bacteria on teeth surfaces (which may cause cavities).


Many people add sugar or sweeteners like honey into their brewed teas which act as food for bacteria causing them to produce more acid thus accelerating staining process.


Drinking hot tea may exacerbate tannin release from leaves thus increasing their ability to bond with teeth surfaces leading  to stains especially when consumed frequently.


The higher concentration of tea used during brewing increases tannin levels released into the drink hence increasing chances for stains formation.

Types of Tea That Stain Teeth the Most

Not all teas are created equal when it comes to teeth staining. Some teas contain more tannins and acidity than others, making them more likely to cause discoloration. In this section, we will explore the types of tea that stain teeth the most.

Maintain good oral hygiene habits and avoid tobacco use, dark-colored food items/drinks to keep your teeth shining bright for years to come. Drinking through a straw, rinsing your mouth after drinking tea, brushing regularly, and visiting the dentist for professional cleaning can help reduce or prevent staining on surfaces. Professional in-office treatments are the most effective and safe option to remove deep-set tea stains. Natural remedies may cause sensitivity and enamel erosion over time.

Black Tea

Black tea is made from fully fermented tea leaves and is one of the most commonly consumed varieties in many parts of the world. It contains high levels of tannins which can stick to your enamel causing yellowish or brownish stains over time. Additionally, black tea’s strong flavor and dark color make it a prime culprit for staining teeth.

Green Tea

Green tea is known for its health benefits because it contains antioxidants like catechins that help prevent cell damage in our bodies including dental plaque buildup . However ,it still has a reputation for being a culprit behind tooth discoloration due to its high concentration of tannins and caffeine content.

White Tea

White tea has less fluoride thus reducing chances for enamel weakening however still contain tannin levels that lead  to stains especially if consumed frequently .

Herbal Teas

Herbal teas like chamomile , peppermint or fruit teas are naturally caffeine-free but they may contain acidic compounds such as vitamin C which can erode tooth enamel leading to more porous surface hence accelerating staining process over time.

Fruit-Flavored Teas

Fruit-flavored teas tend to have higher sugar content in order to enhance taste leading bacteria growth on surfaces causing cavities while also having similar levels of acidity as regular black/green/white herbal teas often leading  to deep stains formation .

Preventive Measures to Keep Teeth from Staining

Preventing teeth staining caused by tea consumption is possible with some preventive measures and lifestyle changes. Here are some tips to help keep your teeth white and bright.

Maintaining good oral hygiene habits combined with minimizing sugar intake, drinking water after tea consumption, and using a straw when sipping hot/warm drinks will help prevent tooth discoloration caused by excessive daily consumption over time. In addition, rinsing out your mouth after drinking tea, brushing regularly, and visiting the dentist for professional cleaning can help reduce or even prevent staining on surfaces. If your teeth are already stained, professional in-office teeth whitening is the most effective way to remove stains caused by tea consumption.

Drink Through a Straw

Using a straw can help reduce the contact of tea with your teeth, minimizing staining. When you drink through a straw, the liquid bypasses your front teeth and goes straight to the back of your mouth.

Rinse Your Mouth After Drinking Tea

Rinsing out your mouth after drinking tea helps remove any leftover tannins or acid that may remain on tooth surfaces, reducing chances for stains formation . Swish water around in your mouth for 30 seconds after taking a sip of tea (or any other beverage/food item known to cause discoloration).

Brush or Floss After Drinking Tea

Brushing at least twice daily combined with gentle flossing can help remove plaque buildup on surfaces thus making it harder for stains to stick onto enamel .

Use Whitening Toothpaste

Whitening toothpaste contains mild abrasives that work as an exfoliant removing surface stains along with additional polishing agents which helps restore natural shine of enamel surface.

Get Professional Teeth Cleanings Regularly

Regular dentist visits are essential in keeping oral health in check while also helping prevent discoloration. Dentists use professional cleaning methods like scaling which removes tartar buildup from tooth surfaces as well as providing recommendations on how often one should get their teeth cleaned based on their individual needs .

Avoid Overconsumption

While drinking moderate amounts of tea provides numerous health benefits , excessive intake may lead  to deep stains formation over time . It is recommended that no more than two cups per day be consumed, especially if you have concerns about tooth discoloration.

Teeth Whitening Options for Tea Stains

If your teeth are already stained from tea consumption, there are several teeth whitening options available to help remove the discoloration. Here are some popular options.

Over-the-Counter Whitening Products

Over-the-counter whitening products such as toothpaste, gels and strips can be found at drugstores or pharmacies without a prescription. They contain mild bleaching agents that work by breaking up surface stains on enamel making them less noticeable. However , it’s important to follow instructions carefully as overuse of these products may lead  to more damage than good .

Professional In-Office Teeth Whitening

Professional in-office teeth whitening is done using stronger bleaching solutions administered by dental professionals like dentists or hygienists . It is the most effective way to whiten teeth caused by tea stains and takes only an hour or so with noticeable results after one session. The process uses a special light which activates the solution on enamel surfaces helping remove deep-set stains thus providing instant results.

Custom-made Whitening Trays

Custom-made trays offer a more personalized approach for removing stains caused by regular tea consumption especially for those with deep stains affecting multiple surfaces . Impressions of your teeth will be taken in order to create customized trays that fit perfectly onto your mouth structure ensuring proper distribution of the bleaching agent onto all tooth surfaces .

Natural Remedies

While natural remedies such as oil pulling , baking soda and apple cider vinegar have been touted as cost-effective ways to whiten teeth caused by tea staining, they have not been proven scientifically effective nor safe long-term use without causing any side effects which may include sensitivity issues and enamel erosion over time.


What causes tea to stain teeth?

Tea stains teeth due to its natural pigments called tannins. These tannins can bind to the enamel on your teeth, causing discoloration. Tea also contains acid that erodes the enamel, making the teeth more susceptible to staining.

Which type of tea causes the most staining on teeth?

Black tea is known to cause the most staining on teeth due to its high concentration of tannins. Green, white, and herbal teas contain fewer tannins and may cause less staining. However, all types of tea can still contribute to tooth discoloration over time.

Can adding milk to tea prevent staining on teeth?

Adding milk to your tea can help reduce staining because the protein in milk can bind to tannins, preventing them from sticking to your teeth. However, adding sugar or honey may increase the staining potential. Additionally, it’s important to note that milk does not completely prevent staining and regular dental hygiene practices should still be maintained.

How can I prevent tea from staining my teeth?

To prevent tea from staining your teeth, you can try drinking it through a straw to bypass contact with your teeth. Additionally, brushing your teeth or rinsing your mouth with water immediately after drinking tea can help reduce staining. It’s also important to maintain good dental hygiene habits and regularly visit your dentist for cleanings and check-ups.
