How Does Drinking Coffee Affect Your Teeth?

There’s no denying the worldwide power and love of coffee. At least half of everyone you know drinks it, and in the USA, it’s more than anywhere else in the world. Regardless of geographical location, coffee is something that many people can’t live without.

If you think drinking too much coffee might be bad for you, you’d be right. One of the most obvious effects of too much coffee, aside from coffee breath, is teeth staining. Coffee can also contribute to enamel wear and a drier mouth, both of which make staining and decay more likely over time.

Polyphenol Staining

The beans that make up coffee contain polyphenol, a substance naturally found in plant based foods. Tannins is a type of polyphenol, and it can cause teeth to get stained due to its association with color. Due to coffee’s dark color, tannins are able to break down in water and allow particles to stick to the surfaces of your teeth. This then results in those particles getting stuck to the ridges and pits of the tooth’s surface, leaving a noticeable hue.

Tooth enamel looks smooth, but it is actually porous at a microscopic level. When you drink coffee regularly, those pigments settle into the pores and build up over time, which is why staining tends to get more noticeable the longer someone has been a daily coffee drinker.

Additionally, adding cream and sugar does not remedy the situation, and instead strengthens the bacteria in your mouth. Like soda, drinking coffee allows for acids to mix with what’s in your mouth, and that’s never good. The more bacteria and acid you allow in your mouth, the more damage your tooth enamel will face. If you are also curious about how acid levels in general affect your teeth, our overview of how pH relates to tooth decay covers the science in more detail.

Coffee, Enamel Wear, and Dry Mouth

Beyond surface staining, coffee’s acidity can gradually soften enamel, which makes the tooth surface more porous and more likely to hold onto stains. Coffee also has a mild diuretic effect, meaning it can reduce saliva production. Since saliva is one of your mouth’s main defenses against decay, helping neutralize acid and rinse away food particles, a drier mouth from frequent coffee drinking can leave your teeth more exposed to both staining and cavities.

Solutions

If you enjoy your coffee, then being told to stop likely won’t work for you. As it is, there are ways to ensure that your teeth don’t stain, even if you drink coffee daily. One of the most simple and effective ways is to drink your coffee from a straw. Most people drink coffee hot, so a straw might appear odd in this case, but less so when iced. The idea is to keep the drink away from the teeth, so a straw would allow the fluid to go straight to the tongue and down the throat.

Another important thing you can do is not drink coffee throughout the day. Having set times when you drink coffee, rather than sipping it for hours, is one of the best ways to decrease the chance of staining teeth, since prolonged exposure gives pigments and acid more time to sit on the tooth surface.

Brushing your teeth immediately after drinking is also not ideal, since enamel is temporarily softened by the acid and brushing right away can wear it down further. You can, however, rinse your mouth with water and wait roughly thirty minutes before brushing. Drinking water alongside your coffee and consuming foods like fruits and vegetables also helps stimulate saliva and break down bacteria.

Staying consistent with your daily brushing and flossing routine matters more for coffee drinkers than for people who skip caffeine altogether, since it directly counters the staining and acid exposure that come with regular coffee consumption. If your teeth have become sensitive along with the staining, it may also be worth reading about whether teeth whitening is safe for sensitive teeth before pursuing a brighter smile.

Frequently Asked Questions About Coffee and Your Teeth

Does decaf coffee stain teeth less than regular coffee?

Decaf coffee contains the same tannins and dark pigments as regular coffee, so it can stain teeth just as much. Removing caffeine does not change the coloring compounds responsible for staining, so the same prevention habits apply either way.

Is it better to drink coffee hot or iced for my teeth?

Temperature itself does not change how much coffee stains your teeth, but iced coffee is easier to drink through a straw, which keeps the liquid from making prolonged contact with your front teeth. If staining is a concern, iced coffee with a straw is a simple way to reduce contact time.

Can a professional cleaning remove coffee stains?

A professional cleaning can remove much of the surface staining that builds up from coffee, since it reaches areas that a toothbrush cannot fully clean. Deeper staining that has settled into the enamel over years may need a whitening treatment in addition to a cleaning.

Does adding milk to coffee reduce its effect on teeth?

Adding milk can slightly dilute the tannins in coffee, but it does not eliminate the sugar or acid exposure, and added sugar can feed the bacteria already in your mouth. Rinsing with water after drinking is a more reliable way to limit the impact than relying on milk alone.
