Why Does Coffee Make My Mouth Dry

Coffee is a beloved beverage worldwide, enjoyed by millions every day. Its taste, aroma, and caffeine kick make it an ideal morning go-to for many.


However, have you ever had that experience where coffee makes your mouth feel dry? If you have, you are not alone. Many coffee drinkers complain about this issue but are often puzzled about why it happens. 

Dry

In this blog post, we will explore what causes coffee to make your mouth dry and what you can do to combat this pesky problem. Stick around if you’re looking for answers!

What exactly is dry mouth

Studies show that dry mouth, also known as xerostomia, is characterized by a decrease in saliva production in the mouth. Not enough saliva in the mouth can lead to a dry, sticky feeling and cause difficulty in speaking, swallowing, and even tasting.

Effects of saliva 

Protecting against tooth decay

Research shows that saliva plays an important role in protecting teeth from decay. It contains minerals, such as calcium and phosphate, that can help to remineralize and strengthen the enamel, the hard outer layer of the teeth.

Aiding in digestion

Saliva contains enzymes that play a vital role in the digestion of food. These enzymes help to break down carbohydrates, proteins, and fats in the mouth and during the initial stage of digestion. This process makes swallowing and digesting food easier and promotes nutrient absorption in the digestive tract. 

Facilitating speech and communication

Saliva plays an essential role in speech and communication. It lubricates the mouth, tongue, and lips, making it easier to form words and articulate sounds. Saliva also helps to moisten the vocal cords, which is necessary for producing clear and effective speech. 

Individuals may experience difficulty speaking without sufficient saliva, including slurred or garbled speech. This can negatively impact communication and lead to social and emotional consequences.

Common symptoms of dry mouth

Common symptoms of dry mouth are discomfort, sore throat, and difficulty swallowing. Xerostomia can lead to bad breath, mouth sores, and a dry, cracked tongue. 

It’s important to address dry mouth symptoms and increase saliva production, such as staying hydrated, using sugar-free gum or lozenges, and avoiding certain medications or lifestyle habits that can worsen the condition. 

For coffee drinkers, it’s especially important to be aware of the potential for coffee to exacerbate dry mouth symptoms and to take measures to reduce its effects, such as drinking plenty of water and choosing less acidic blends.

Coffee ingredients that dry out the mouth

Coffee contains a couple of ingredients that could cause dry mouth. Some of these ingredients are:

Caffeine

Studies show that coffee contains caffeine which is a natural diuretic. This means that it increases urine production in the body, which can lead to dehydration. When the body is dehydrated, it produces less saliva, leaving the mouth feeling dry and uncomfortable. Caffeine can also inhibit saliva production. 

Chlorogenic acid 

Research proves that chlorogenic acid is a molecule found in coffee that has been shown to reduce saliva production, leading to dry mouth. This is why it is important to be mindful of the types and amount of coffee consumed, especially for individuals prone to dry mouth.

Tannins and their astringent properties

Tannins, commonly found in coffee, tea, and red wine, are responsible for the astringent or dry sensation in the mouth. Research shows that tannins are bound polyphenols that shrink proteins and precipitate, resulting in their astringent properties. While tannins can be found in many plants, their presence in coffee can reduce saliva production

Tips for reducing the effects of coffee on dry mouth

There are ways to reduce coffee’s effects on your oral cavity.

Avoid highly acidic coffee blends

Avoiding highly acidic coffee blends is one effective way to reduce the effects of coffee on a dry mouth. As stated earlier, coffee contains chlorogenic acid, which can decrease saliva production, leading to a dry mouth. 

Individuals can better manage this side effect by opting for lower-acidity coffee blends. It’s essential to note that different brewing methods can also affect the acidity of the coffee. Choosing a cold-brew process or adding eggshells to your coffee beans can significantly reduce acidity.

Drink water before and after consuming coffee

To reduce the effects of coffee on a dry mouth, drinking water before and after consuming your favorite blend is important. By drinking water, you can help counteract the dehydrating effects of caffeine and keep your mouth hydrated. 

Use a straw

One effective way to reduce the effects of coffee on dry mouth is to use a straw. By doing so, the coffee can effectively bypass the front teeth, which decreases contact with the mouth and reduces the risk of developing dental stains. 

Using a straw can also help protect the teeth from the harmful effects of highly acidic coffee blends. However, it’s important to note that while drinking through a straw can be beneficial, it’s not a foolproof method for eliminating staining. To get the most out of this strategy, it’s recommended that people position the straw towards the back of their mouths while sipping their coffee or other beverages. 

Chew gum to stimulate saliva production

Chewing gum is a simple yet effective way to promote saliva production and combat dry mouth caused by coffee consumption. Gum-stimulating salivary flow can also aid digestion and improve overall breath freshness. 

When choosing gum, it is important to avoid options that contain sugar, which can contribute to dental problems. Instead, opt for a sugar-free gum that contains xylitol, a natural sweetener that is beneficial for oral health. 

In addition to promoting saliva production, gum can provide a satisfying chew to help reduce coffee cravings. So, next time you reach for a cup of coffee, consider adding sugar-free gum as a helpful companion to keep your mouth fresh and hydrated.
