How to choose a humidifier for dry mouth

If asked to propose a solution for people who have a dry mouth, a humidifier would probably be one of the last things you would think of, if at all.

A humidifier does work wonders for those with skin issues and allergies, and its effects are not limited to that area. When you notice that the dry air from your home or office accentuates the symptoms of dry mouth, you could benefit from using a humidifier to keep your mouth and respiratory system at optimal moisture levels.

How Can a Humidifier Help with Dry Mouth?

In case you know absolutely nothing about this condition, dry mouth is also known as xerostomia and it comprises the inability of the salivary glands to produce enough saliva, therefore it leads to experiencing cracked lips, frequent thirst and a general sticky feeling in the mouth and throat area.

But how can a humidifier help when your salivary glands do not produce enough moisture to lubricate the mouth? Sometimes, a dry mouth is a consequence of environmental conditions. If the space you live or work is characterised by a lack of humidity, you might encounter symptoms of dry mouth.

By increasing the humidity levels of the ambient air, a humidifier enhances your breathing and helps with the symptoms of dry mouth.

Choosing Between Cool Mist and Warm Mist Humidifiers for Dry Mouth

Picking the best humidifier for your specific requirements can sometimes be confusing. While warm mist humidifiers are best during cold winter days and nights, if you are looking for the best humidifier for dry mouth at night, for example, choose a model that does not need frequent refills.

So, look for a cool mist humidifier with a larger tank.

Important Features When Purchasing a Humidifier for Relieving Dry Mouth

Types of Humidifiers and Their Features

There are various models of humidifiers available on the market and most of them offer extra features, apart from the usual function of this product, which is to regulate the moisture levels in your environment. Before purchasing a humidifier for dry mouth, spend a little time comparing their features and test some essential elements that will make a difference for relieving your symptoms.

If you choose a steam vaporizer, know that these products use electricity to create steam, that is cooled down and then released into the air. Ultrasonic humidifiers, on the other hand, produce steam by using vibrations instead of electricity.

Last, but not least, there are evaporators, whose system blows air past evaporating water to produce humidity. If you are going to use it in a space that is frequented by children, a wise option would be an impeller humidifier, or a cool mist humidifier, as it vaporizes water using rotating disks instead of heat, which can be dangerous to pets and children.

Another valid option is the one comprising a central humidifier. This is ideal if you intend on connecting it to the AC in your living or working area.

As you may notice by skimming through some customers’ reviews on Amazon, for example, people with dry mouth usually choose ultrasonic cool mist humidifiers to relieve their symptoms.

The Size of a Humidifier Matters

You should consider the dimensions of the area where you are going to use a humidifier and check the square footage that the product can reach before purchasing. A three-gallon unit, for example, could cover up to 800 square feet, whereas small, travel-sized humidifiers will probably reach 100 square feet.

Water Tank Capacity and Noise Levels of a Humidifier

While the water tank capacity will directly influence the way your machine will satisfy your needs, such as run all night with no refill, noise levels are also important if you want a quiet environment and plan on getting a good night’s sleep while being properly hydrated.

How to Deal With Dry Mouth

Humidifiers are a necessary part of any household. They can help you beat the winter dry air, or humidify your room during the summer. But what is the best humidifier for dry mouth? Why would I need a humidifier? Getting rid of dry mouth can be a difficult thing to do.

The most common reason people suffer from dry mouth is the lack of saliva, which is mainly caused by medications. Not everyone feels comfortable talking about how they deal with oral problems like this one. That’s why many people tend to keep quiet until the problem becomes unbearable or frustrating.

This is inadvisable because you should stay on top of your condition in order to avoid getting worse, as well as certain complications that might arise along the way. So what happens when you don’t treat your dry mouth?

Some consequences of not treating this condition include bad breath, tooth decay and tooth loss, infections and even cavities and other gum problems.

1) Bad breath

Bad breath is usually caused by not brushing your teeth for long periods of time. It’s also possible to have permanent bad breath after a cold, which is why you should brush your teeth more frequently if you have been sick in the past few weeks. If you are suffering from bad breath, then this is definitely a sign that your mouth and throat are probably dry.

Bad breath can also be caused by excessive amount of tongue bacteria.

The bacteria responsible for bad breath can be found on the back surface of your tongue and gums, but there’s not much you can do about it since these areas are hard to reach without using appliances like toothpicks or other oral hygiene tools.

2) Tooth decay

Tooth decay is one of the most common oral problems, and it’s one of the easiest to prevent. Before you know it, your teeth will start to feel achy and painful, and they’ll need to be either extracted or fixed in order to avoid further damage.

This can be incredibly expensive, which is why many people are at risk for tooth decay. According to Oral Health America:

About 20% of Americans currently have some form of dental decay.

3) Tooth loss

Another unpleasant consequence of not addressing your dry mouth is tooth loss. According to “Dry Mouth: The Facts,” more than five million Americans suffer from tooth loss.

This is a very large number, and it can be quite alarming because it can also lead to other dental problems. Tooth loss can happen in one completely or in various parts of the mouth.

Most people refer to this condition as oral-facial-digital syndrome (OFDS). If you have this problem, then usually you will need to go to the dentist for treatment, and the first step should be addressing your dry mouth.

4) Infections

Overtime, bacteria will start to build up on your tongue. This is a condition known as Gingivitis. Gingivitis can be treated by simply having your gums cleaned, but it’s also possible to prevent it from happening in the first place by making sure you brush twice a day and flossing at least once a day.

If you want to prevent further damage, then the Centers for Disease Control and Prevention (CDC) recommends that you clean your teeth at least twice a day with an antiseptic mouthwash or rinse.

5) Humidifier for dry mouth

There are many options for humidifier for dry mouth, but because I have experienced the effects of having a dry mouth myself, I want to share with you something that helped me cope with the symptoms: using a humidifier.

There are many types of humidifiers like steam and ultrasonic ones. You can find them online or in many big retail stores like Costco. The reason I decided to recommend a certain one is because I’ve used it myself (and still do), and it helped my condition quite a bit.

6) Medications

Medications are a common cause of dry mouth, and they can be quite difficult to treat. If you have dry mouth, then you might need to adjust your current medications in order to treat it.

Do not stop any medication without talking to your doctor. Usually it’s possible to get by with more water, but if that doesn’t work, then there are certain drugs like Biotene and Aquafresh for people dealing with this condition.

Over-the-counter medications like these can help you manage your symptoms and feel better overall.


If you want to regain your mouth moist and feel like yourself again, then there are many ways to do it. The first step is to talk to your doctor about it. Your doctor will ask you about any medications you are on, and they’ll also ask you questions regarding lifestyle habits that can impact the symptoms of dry mouth.

According to Mayo Clinic:

"A number of factors may cause or contribute to dry mouth, including prescription drugs, various medical conditions and lifestyle habits. Some people may find that the benefits they gain from using these drugs or habits outweigh the potential risk for dry mouth. If dry mouth is a side effect that bothers you, your doctor may consider alternatives or change your dosage."


Please Note: Just because a humidifier is marked, for example “Baby Room”, it will still work for other things, for example “Living Room” or “Plant Humidifier”
