How Coffee Can Impact Your Teeth

If you’re a regular coffee drinker, unfortunately, you’re doing damage to your teeth without realizing. Understandably, a lot of people need a caffeine shot every morning and throughout the day to keep themselves going ahead of a busy daily schedule, whether it be at work or leisurely.

It is time to introduce some of the oral health impacts coffee has to your oral health if you’re not aware of what they are. Coffee is one more the most popular beverages. It increases mental alertness and energy levels. Whilst there are some positives, it is equally important to understand the impacts of coffee on your teeth.

Without further ado, let’s take a look at these impacts so that you act to reduce your coffee intake, or improve your oral routine to keep your teeth clean.



Coffee is a significant culprit for discolouration. Discolouration is the process of your teeth showing stains which can darken your tooth shade and reduce your smiling confidence. The enamel becomes exposed, which is the extrinsic (outer) layer of your teeth. When this happens, you will eventually notice a yellow or light brown shade forming around your teeth, and this is likely to be because of coffee. At a check-up and clean appointment, it might become more challenging to restore the whiteness in your teeth if you keep consuming coffee.

Tooth Enamel Damage

Coffee contains acidic properties, and these acidic properties can trigger an acid attack on your teeth which can lead to tooth decay. Coffee is also attributed to dry mouth (read more about dry mouth here), and without moist saliva, coffee properties will remain in your teeth. Saliva protects your mouth by washing down your food from the mouth. Without it, enamel can become damaged from the acid attack.

Bad Breath

If you’re not aware, coffee can leave a bad odour within your mouth. The coffee properties remain on the tongue after drinking it to cause bad breath. A recommended solution is to tongue scrape your tongue or use mouthwash after drinking to keep your breath fresh and remove those odour properties off your tongue.


Cavities are part of the tooth decay process. A cavity is a hole in the centre of the tooth root where, ideally, dental filling treatment would be required to fill it to avoid it damaging the tooth any further. Consuming regular amounts of coffee can cause your teeth to become brittle if your enamel is exposed to harmful bacteria. Eventually, this can lead to a cavity.

How To Drink Coffee And Keep Teeth Strong

One of the questions coffee lovers will want to know is, how can they drink coffee whilst keeping their teeth healthy and strong? Firstly, reduce the amount of coffee you consume, or consider consuming black coffee without sugar properties. It is not something coffee lovers want to hear, but it is an important step. Also, consider rinsing your mouth with mouthwash and perform tongue scraping to avoid bad breath. This will help to keep your mouth clean from coffee debris becoming stuck, because plaque and harmful bacteria may eventually build up.

Continue to consume your favourite coffee! Although, be mindful of its impacts.
