Drinking coffee is one way to ensure that you will have to deal with stains on your teeth. There are tactics to employ to limit staining, and there are methods to de-stain teeth. Taking care of your teeth with regular visits to the dentist is one proven strategy.

Why does coffee stain your teeth? How coffee stains form

Roasted coffee contains micronutrients (polyphenols) known as tannins. Tannins are potently antioxidant, anti-inflammatory and anti-bacterial. But in coffee, they are acknowledged as chromogenic agents that enable color compounds to stick to your teeth. 

Drinking one cup of coffee a day is enough to make your teeth develop a yellow hue. Tannins break down in the water and are absorbed into your enamel, where they can accumulate if unchecked. They do not discolor teeth, but they allow other staining agents to be absorbed by the enamel and dentin.

Some studies tell us that drinking an acidic beverage before your cup of coffee can worsen the degree of tooth discoloration. Coffee also contains chlorogenic acid (CGA) compounds that can cause the external discoloration of the enamel.

Coffee industries do not pay much attention to proper smoke disposal, so most of the smoke produced during the roasting process ends up re-deposited onto the coffee beans during the pyrolysis stage. It causes their color to change from brown to black and increases their tannin levels.

How to prevent coffee stains

The best way to prevent coffee stains is to quit the beverage entirely. However, there are other ways to minimize tooth discoloration without giving up your morning cup of coffee.

Instead of starting your day with a cup of black coffee, consider green tea. It contains fewer staining agents, and it could offer health benefits.

In 2010, researchers examined studies of green tea and determined that the ingredients in green tea could help to reverse some problems caused by a high-fat diet and obesity. Green tea could also aid in the prevention of cancer and heart disease.

Some people use straws to sip drinks that might stain their teeth. While a straw can keep these fluids from touching the front of your teeth while you drink, the fluid can slide across them when you close your lips to swallow.

A straw could help to reduce staining risks from some drinks, but know that this method can’t offer complete protection.

Dairy products contain the protein casein, which attaches to tannins in coffee and prevents them from getting onto your enamel

Practice drinking coffee in one sitting instead of taking little sips throughout the day. This way, you can prevent bacteria and tannin buildup, and it will be easier to rinse out your mouth after each cup of coffee.

Make a habit of drinking some water after your coffee. This allows you to rinse out any residual tannins before they have a chance to settle on your enamel.

Although brushing your teeth after meals is recommended to prevent plaque buildup, it is not always advisable to do so immediately after you eat or drink something acidic. Brushing your teeth after an acidic meal or beverage will wear down your enamel and promote tooth discoloration.

There are better ways to clean your teeth after drinking coffee, so if you can avoid brushing immediately after, it’s far more beneficial.

However, brushing and flossing your teeth regularly is the key to preventing plaque and bacteria buildup in your mouth.

Seeing a dentist once every six months can help you stay on top of any coffee stains on your teeth, whether you’re an avid java lover or a casual drinker. It is not an excuse to drink more coffee, but it is a surefire way to keep your oral hygiene in check regardless of your lifestyle.

A recent study found that 80% of Americans between 18 and 49 wish their teeth were whiter.

Home remedies for coffee stains

Changing what you eat and drink is the best way to ensure that coffee doesn’t stain your teeth. However, if you can’t break the coffee habit, you can use simple home remedies to remove the stains. Here are some options to try:

Some forms of toothpaste contain mild abrasives like baking soda. They can only remove stains on the surface of the teeth, explains the American Dental Association. However, a product like this could help to reverse some of the stains left behind by your cup of coffee.

Safe toothpastes contain a seal of approval from the American Dental Association and are safe for you to use. Don’t try to make your own toothpastes at home with baking soda or charcoal, as they may not be safe to apply to your teeth.

Switch to an electric toothbrush to get more cleaning power for daily stain removal. In a study published in 2022, researchers examined the stain removal efficacy of electric toothbrushes. They found that these toothbrushes were very effective in removing stains, and they didn’t cause significant damage to the tooth’s enamel.

The American Dental Association recommends brushing your teeth for two minutes twice per day with a soft-bristled brush. This practice is doubly important if you’re an avid coffee drinker as it prevents the accumulation of tannins and discoloring bacteria. Brushing your teeth regularly also prevents halitosis (bad breath), and a regular side effect of drinking coffee is “coffee breath.”

Several companies sell products that can remove stains on the surface of your teeth. The American Dental Association explains that these kits often have a smaller concentration of bleaching agents than those used in dental offices, and they’re safe if they have the ADA seal of approval. If you want to use these products, ask your dentist first and ensure you’re using a product that’s right for your smile.

The American Dental Association explains that there are several DIY approaches that people claim can whiten teeth. They include using acid-containing fruits, drinking vinegar, or swishing oil inside your mouth. 

Some of these approaches are unproven, and others are associated with damage to your teeth. Before you use anything in your mouth to whiten your teeth, talk to your dentist about your plans and ensure it’s safe.

Professional remedies for coffee stains

If home remedies don’t work, your dentist can be a good resource. The following two main treatment options are available:

Your dentist can create a tray for bleaching and provide a safe product you can use at home. Typically, this involves using a small amount of a product inside your trays and wearing them for a time that’s outlined by your dentist. These products are typically stronger than over-the-counter versions, and your dentist can ensure you’re using them safely.

Your dentist may also provide whitening in one or two appointments inside the office. Your dentist applies the treatment and supervises the process, so it’s a safe and effective method of removing coffee stains. Some dentists use a paint-on product, while others use lasers.

If your teeth are stained and chipped, your dentist may suggest a more significant option. Dental veneers are thin shells that sit on the outside of your teeth and cover up what’s below them. They can be stained with substances like coffee, so you must skip your regular cup. But they can solve an existing staining problem immediately.

If your teeth are stained and damaged through cracks or cavities, your dentist may suggest dental crowns. These products sit like caps over your teeth, providing exceptional care for damaged teeth. They can also be stained with coffee, so paying attention to what you eat and drink is important.

How to prevent teeth staining with diet

We’ve outlined how coffee can stain your teeth. Unfortunately, it’s not the only substance that can leave stains on the surface of your teeth.

Common things  that can stain your teeth include the following:

  • Beverages: Drinks like red wine and black tea can leave stains on your teeth. Dark cola can stain teeth too.

  • Fruits: Dark-colored berries can leave stains behind. So can tomatoes and tomato sauce.

  • Condiments: Soy sauce, vinegars, and berry sauces can leave stains on your teeth.

Cutting back on these substances can help to keep your teeth white. However, eliminating all sources of staining isn’t possible. Consider brushing your teeth after consuming these items.
