Is Coffee Bad For Your Teeth? How To Prevent Coffee Stains

Coffee is the most consumed beverage and is a billion-dollar industry. Across the globe, over two billion cups are drunk daily. Coffee is an indulgence enjoyed by many. Unfortunately, coffee adversely impacts your teeth with coffee stains and advances acid-producing bacteria.

Coffee is bad for your teeth. Three coffee ingredients responsible for stains are tannins, chromogens, and melanoidins. Also, coffee increases acidity and fosters bacteria growth. There are simple measures to treat the effects of coffee- prevent and remove preexisting stains.

Although prolonged coffee consumption harms oral hygiene, it doesn’t have to be permanent. Primary care and affordable home recipes offer various solutions that will assist. So, you don’t have to take coffee out of your daily routine.

Yes, coffee negatively affects your teeth. Diseases like cavities, discoloration, halitosis, enamel erosion, plaque, decay, gum disease, and yellow teeth result from excess coffee drinking. Also, a failure to properly treat symptoms will accelerate the adverse consequences.

Understanding The Effects Of Coffee On Your Teeth

Coffee negatively impacts your teeth:

  • Cavities
  • Enamel erosion
  • Plaque
  • Gum disease
  • Tooth Decay
  • Discoloration
  • Yellow teeth- exposed dentine layer

Coffee causes cavities. Just one cup of coffee a day significantly increases the likelihood of cavities. Also, coffee’s thick texture and heavy aroma attach to your mouth’s interior. This forms bacteria, which incubates and fosters halitosis (bad breath).

Enamel erosion from coffee is harmful to your teeth. Beyond the unsightly appearance of yellow teeth, enamel erosion presents health risks that will create considerable pain. This is because it’s the deterioration of your tooth’s exterior protective layer. In addition, it advances bacteria growth and produces acid.

Plaque, gum disease, and tooth decay result from drinking excess coffee. These diseases are caused by plaque bacteria that convert sugar into acid. If these issues aren’t treated, they’ll lead to severe complications, intolerable pain, and tooth loss.

Coffee notably discolors your teeth. Discussed more fully below, discoloration is from the tannin in coffee. Tannin in tea and wine is also responsible for teeth stains. Just one cup of any of these beverages will result in discoloration.

Another serious issue is yellow teeth. This is when the dentin is exposed as the enamel is thoroughly eroded. Thin and flimsy enamel develops from rapidly demineralized teeth, and your teeth become permanently yellow as the dentin surfaces.

Tooth enamel is the strongest, hardest human tissue. When damaged, it’s permanent as this tissue doesn’t regenerate. The enamel defends against nerve exposure. Increased sensitivity to temperature and textures is an indication of enamel erosion.

Why Is Coffee Bad For Your Teeth?

A primary reason why coffee spoils your teeth is due to a highly acidic oral environment, which is a pH level that is lower than five-point-five (5.5). Coffee is naturally acidic and has a pH level of five. Drinking coffee further exacerbates problems caused by a lower-than-five pH level.

The tooth’s enamel consists of various minerals. Hydroxyapatite is the first mineral layer that is responsible for safeguarding the tooth. Hydroxyapatite is the reason your teeth appear white and shiny. Unfortunately, a highly acidic interior erodes this vital protective coating.

Sipping coffee dissolves and demineralizes the vital mineral layers. Also, coffee creamer has sugars and colorings that quicken bacteria growth. The enamel is porous and acid-converting bacteria will quickly change sugar into tooth decay.

Certain harmful bacteria need the right pH environment to grow. Elevated acidity sustains cavity-causing bacteria proliferation. So, coffee doesn’t directly cause cavities. Instead, it cultivates the ideal atmosphere for bacteria growth. 

Coffee has naturally-occurring sugars which are inescapable. Even if you remove sugar altogether, your teeth enamel is still at risk. Discussed below are other ingredients that fasten the chemical compounds to your teeth- exacerbating the problem. It would be best if you took proactive measures to protect your teeth.

Why Does Coffee Stain Your Teeth?

Enamel staining is one of the main consequences of drinking coffee. Staining is caused because coffee contains tannins. Tannins are an organic compound that belongs to the polyphenol family. They act as an adhesive that fastens color compounds to the teeth. The effects are a brow-yellow residue that’s a challenge to remove.

Tannins are responsible for the bitter taste of coffee. Despite the adverse effects of tannins, they contain beneficial antioxidants that promote stomach health. Tannins also have properties that prevent gum disease. Yet, tannins also have carcinogenic attributes.

In the presence of water, tannins automatically bind to dissolved proteins. This process creates complex tannin-protein molecules. They wrap in successive layers on the tooth’s surface. As the compounds are complex, the stains are challenging to eliminate.

In addition, coffee contains chromogens. These are biochemical pigments or pigment-constructing microbes. As oxygen interacts with chromogens, it produces a yellow compound that secures itself to the exterior tooth.  

Melanoidins are a pigment produced when coffee cherries are roasted into coffee beans. Unfortunately, these also contribute to black and green discoloration.

Are Coffee Stains Harmful To Your Teeth?

Yes, coffee stains are harmful to your teeth. Stains maintain the adverse oral situation for prolonged periods. Moreover, they foster an unhealthy environment. The color compounds penetrate the porous mineral layers reducing enamel strength and exposing the dentine and nerves.

Additionally, it’s essential to consider the psychological impact of having teeth stained yellow-brown. An unattractive smile causes self-esteem issues and unnecessary strain. Preventing and reducing stains will immediately result in confidence and increased well-being.

Can I Drink Coffee And Not Stain My Teeth?

Unfortunately, you can’t enjoy a cup without staining your teeth. However, various methods assist with residue removal and stain prevention. You can take several natural measures to combat coffee’s adverse effects on teeth.

Can You Drink Coffee With Invisalign Or Bracers?


It’s best not to drink coffee with Invisalign. Instead, take them out, and drink your coffee. The dark pigments of coffee will stain the tray, and the heat will warp the mold. Also, drink a glass of water with your coffee. After your coffee, rinse your mouth with water, wait thirty minutes, and brush your teeth. Always drink iced coffee with a straw.

For those with bracers, coffee will cement along the brackets and bands, increasing the likelihood of permanent stains and damage. Try to limit your intake and follow the measures below. However, avoiding coffee is better if you have Invisalign or bracers.

Tips For Coffee Lovers To How To Prevent Coffee Stains

These tips are for all coffee lovers and those with Invisalign and bracers.

Limit Your Coffee Intake

This makes sense as the less coffee is consumed, the less it can influence your mouth’s bacteria and be in direct contact with your teeth. So, reducing the amount of coffee is a significant first step to preventing coffee stains.  

Avoid Sugar And Extra Creamers

Some references state that coffee creamers and milk dilute the potency of black coffee and therefore assist in stain prevention. However, new research suggests milk creamers and sugars only accelerate stain formation. So, avoid extra creamers and sugar.

Substantially reduce the amount of sugar, syrup pumps, and sweeteners in your coffee. Try and cut out sugar and sweeteners altogether. As the bacteria turns sugar into acid, imagine the amount of damage done to the porous mineral layer of tooth enamel.

Finish Your Coffee In Under Ten Minutes

Extending one serving throughout the day is a significant contributor to stain formation and bacteria growth. Each sip introduces a fresh recipe for discoloration and disease. The prolonged time increases the amount of sugars and acids and bacteria growth.

Have Water With Your Coffee

Drinking a glass of water with or after coffee is a simple method to combat discoloration. Try making a habit of drinking a glass of water after your beloved cup of joe. Also, coffee can dehydrate your body. So, following each cup with a glass of water will rehydrate and promote good health.

Gargle with water after every cup. Salvia is pivotal to protecting your teeth and neutralizing the acid content in your mouth. A simple water rinse works the salvia around your mouth’s interior, washing away fast-adhering coffee deposits.

Drink Through A Straw

Whenever you have iced coffee, drink through a straw. A straw immediately surpasses coffee’s contact with teeth, gums, and tongue. This doesn’t prevent 100% of stains. Yet, it is a worthwhile measure. Ensure they’re eco-friendly straws.

Practice Good Oral Hygiene

Daily flossing, mouthwash, and brushing significantly reduce coffee stains and their adverse effects. Habitually caring for your teeth prevents, decreases, and removes stains.

How To Remove Coffee Stains On Teeth?

how to remove coffee stains

Coffee drinkers can rest assured as coffee stains can be prevented and removed. Additionally, the scientific community in dentistry invests time and money in investigating dental protection and care. So, newly sanctioned products are frequently introduced into the market. Here are a few measures you can take to prevent or remove coffee-stained teeth:

Invest In Dentist-Approved Whiteners

During your bi-annual trip to the dentist, inquire about teeth whitening. Unfortunately, teeth whitening can be expensive. There are store-bought options that can mediate discoloration and stains. Ask your dentist for the best brand.

Allow 30 Minutes After You Cup Before Brushing

As acid and bacteria growth is the primary problem of stains, brushing straight away will weaken the enamel. Waiting for 30 minutes lets the mouth naturally readjust its pH levels.

Get An Electric Toothbrush

Usually, electric toothbrushes are scientifically formulated to apply the correct amount of pressure to preserve enamel and effectively eradicate stains. Although they’re pricey, they’re a worthwhile investment for the long-term care of your teeth.

Invest In Sugar-Free Gum

Gum is an excellent solution for physically removing coffee residue. Ensure that it’s sugar-free. Also, gum stimulates salvia, which restores the natural pH balance of your mouth.

Natural Remedies To Remove Coffee Stains On Teeth

A well-known natural remedy to remove stains from enamel is brushing with baking soda twice weekly. Sodium bicarbonate is found in baking soda, which is a weak alkaline and will neutralize the acidic properties in coffee. In comparison, baking soda is caustic, which assists with stain removal.

Mix baking soda and water and form it into a thick paste. Use the paste twice a week straight after brushing. Then, apply it to your toothbrush and brush for a few minutes. Remember not to brush too vigorously, which will erode enamel and harm your gums.

Another option is to combine hydrogen peroxide with baking soda. Take an eyedropper, and mix a few drops in the baking soda. Brush with this mixture once a week. After brushing, leave the homemade paste on your teeth for 20 minutes. Do this once every two weeks.

Some foods like certain raw vegetables, lemons, and strawberries naturally combat harmful bacteria, negate lousy breath, and promote pH balance. This is because they consist of tough natural fibers that gently remove bacteria with every chew.

Strawberries contain vitamin C and malic acid, excellent ingredients for removing stains. You can combine either crushed strawberries or fresh lemon juice with baking soda. After brushing with the paste, you can leave the paste on for five minutes and then rinse.

Another affordable and easy way to combat coffee stains is to gargle apple cider and vinegar with warm water for about ten minutes. Gargle once a day before and after brushing. Please don’t use it too much, as it’ll cause enamel erosion. Be reasonable in your mixtures.

Substitute your coffee with green tea. You don’t have to abstain from coffee entirely. However, to help minimize intake, try green tea instead. Green tea is scientifically proven beneficial to oral hygiene and teeth.

What Will Happen If I Don’t Remove The Stains?

The stains will worsen and eventually cause cavities, decay, and tooth loss. It’s an excruciating process as your nerves will be exposed. Also, it’s irreversible. Simple oral hygiene is an effective means to safeguard your teeth.

The stain prevention measures discussed in this article are easy to do. Limiting coffee intake can, at first, be challenging. However, with a bit of commitment, it becomes easier. This is also true for eliminating sugars and sweeteners. Some report that removing sugar resulted in significant weight loss- two to three pounds a month.

Changing coffee to green tea is worthwhile as green tea is incredibly healthy and releases beneficial neurological chemicals that give the drinker a feeling of well-being. Additionally, green tea advances excellent oral hygiene and weight loss.

Simple things like drinking and rinsing with water, chewing sugar-free gum, and drinking through a straw are effortless compared to the consequences of not being mindful of coffee’s negative impact on teeth.

Other Factors That Stain Your Teeth

Unfortunately, many other factors (like certain foods and drink) can adversely impact your teeth. For example, you must guard against smoking, tea, red/white wine, candy, various citrus fruits, grapes, and berries. Also, practice good oral hygiene habitually.


Smoking is detrimental to your oral health. Cigarettes consist of tobacco which contains tar and nicotine. As soon as these chemicals encounter oxygen, they react by turning brown. Also, smoking reduces the amount of saliva, which has natural antibacterial, antiviral, and antifungal properties.

In addition, habitual smoking compromises your immune system, improving the chances of gum disease. Infection can result in tooth loss. Smoking causes bacteria to increase, making the teeth highly susceptible to rot and decay.

Blood flow to gums is significantly reduced due to smoking. Blood flow is essential for the healing process. Therefore, gum disease is challenging to treat effectively. The more you smoke, the more your teeth are at considerable risk.

Certain Foods And Drink

As mentioned above, tannins are predominantly responsible for teeth discoloration. Tannins are found in red wine and tea. Red wine has a potent combination of various acids and pigments, which will stain your teeth.

White wine is another culprit you must heed. The alcohol is full of sugars and acids that will erode the delicate porous surface of the tooth. Likewise, sodas, juice, and energy drinks have an excess of sugar that is detrimental to oral health.

Citrus fruits, grapes, and berries have natural sugars and acids (like lemon), which will damage your teeth if proper care isn’t taken. Blueberries, blackberries, and cherries contain dark natural dyes that will adhere to your permeable enamel.

Additionally, watch out for balsamic vinegar, tomato sauce, various spicy curries, beets, and candy, as all of these contain acids, pigments, and sugars, which will corrode the surface layer of your teeth.

Poor Dental Hygiene

Regular dental hygiene includes brushing twice daily, flossing, and rinsing with mouthwash. Habitual maintenance of teeth will protect, prevent, and reduce teeth discoloration. If oral hygiene isn’t practiced, plaque will build up, increasing bacteria, resulting in gum disease, tooth decay, and loss.


Coffee contains tannins, melanoidin, and chromogens that leave a harmful residue on teeth. Also, coffee increases the acidity level in your mouth, which causes bacteria growth. These bacteria convert naturally-occurring sugars in coffee to acid that eats away at the enamel. However, coffee stains can be prevented and removed via simple methods.
