What Do Coffee Stains on Teeth Actually Look Like?

Ah, coffee – the beloved morning drink that helps kickstart our day and keeps us going. Many of us rely on a cup (or maybe more) of joe to wake up and feel alert. But have you ever wondered what all that coffee is doing to your teeth?

As a coffee lover myself, I was curious about the effects of this dark elixir on my pearly whites. So, I delved into the topic and discovered that coffee stains are a common concern among avid coffee drinkers. In this article, I will explore what exactly coffee stains on teeth look like and why they occur.

What causes coffee stains on teeth?

Before we delve into the appearance of coffee stains, let’s understand the science behind it. Coffee is a highly pigmented beverage, containing compounds known as tannins. These tannins are responsible for the deep color of coffee and are notorious for their ability to cling onto tooth enamel.

How do coffee stains form on teeth?

When you take a sip of your morning brew, the tannins in coffee begin to coat the enamel on your teeth. Over time, the accumulation of these tannins can lead to discoloration, causing your teeth to appear yellowish or brownish.

The appearance of coffee stains

Coffee stains on teeth can vary in appearance, depending on factors such as the duration and frequency of coffee consumption, oral hygiene habits, and the inherent color of an individual’s teeth. Here are some common types of coffee stains:

Surface stains

Surface stains are the most common type of coffee stains. They appear as thin layers of discoloration on the outermost layer of tooth enamel. Typically, these stains are yellowish in color and can be easily addressed through regular brushing and dental cleanings.

Intrinsic stains

In some cases, coffee stains can go beyond the surface and penetrate the enamel, leading to intrinsic stains. These deeper stains are generally more difficult to remove and may appear as brown or dark spots on the tooth. Intrinsic stains often require professional dental treatments for effective removal.

Dark lines along the gumline

Another form of coffee stain is the development of dark lines along the gumline. These stains occur when the pigments in coffee seep into the small gaps between the teeth and gums. They appear as thin lines of discoloration and may require specific cleaning techniques by a dental professional.

Tooth erosion

While not directly related to the appearance of coffee stains, it’s important to mention the potential impact of coffee on tooth erosion. Coffee is acidic, and when consumed frequently or in excessive amounts, it can gradually wear away tooth enamel. This can make your teeth more prone to staining and may contribute to the overall discoloration.

Preventing and addressing coffee stains

Now that we know what coffee stains can look like let’s explore some preventive measures and solutions to address them.

Good oral hygiene

Maintaining a proper oral hygiene routine is crucial in preventing and minimizing coffee stains. Regularly brushing your teeth with a whitening toothpaste and flossing can help remove surface stains and prevent them from developing further.

Limit coffee intake

Reducing your coffee intake or opting for lighter roasts can also help prevent excessive staining. Additionally, sipping coffee through a straw can minimize contact between the liquid and your teeth, reducing the potential for stains.

Rinse after consumption

Rinsing your mouth with water immediately after enjoying your coffee can help wash away some of the staining compounds, minimizing their effects on your teeth. It’s a simple and effective habit that can make a noticeable difference.

Professional teeth whitening

If coffee stains have already taken their toll on your teeth, professional teeth whitening treatments can help restore your smile to its former glory. Dentists offer various whitening options, such as in-office treatments and take-home kits, that can effectively lighten the appearance of coffee stains.


Coffee stains on teeth can range from surface discoloration to deeper intrinsic stains, with each individual experiencing different levels of staining. By maintaining good oral hygiene practices, limiting coffee intake, and seeking professional solutions when needed, you can prevent and address coffee stains effectively.

So, while indulging in that daily cup of coffee, remember to take care of your teeth to keep them looking radiant and healthy. Cheers to a beautiful smile, coffee lovers!
