Which mouthwashes for dry mouths are best?

Dry mouth is an uncomfortable condition that can be caused by medication, diet, or other health and lifestyle factors. In many cases, however, dry mouth can be significantly improved with the right mouthwash. 

Mouthwash is known for freshening breath and improving oral health, but mouthwash designed specifically to combat dry mouth increases saliva production and can provide some much-needed and soothing relief. Our top pick is Biotene Oral Rinse Mouthwash for Dry Mouth, which users love for its alcohol- and sugar-free formula.

What to know before you buy mouthwash for dry mouth

Dry mouth treatment

Dry mouth isn’t just an uncomfortable condition. If severe enough and left untreated, dry mouth can lead to other chronic conditions, such as bad breath, mouth irritation, infection and teeth and gum damage. 

Often snoring and lifestyle choices, such as tobacco and alcohol use, contribute to dry mouth. Eliminating these potential causes can be the best form of treatment. If there are no outside contributing factors, it’s often the lack of natural saliva production that causes dry mouth. The ingredients in mouthwash are formulated to simulate saliva to moisten the mouth and help fight bacteria. 


The one thing that mouthwashes specifically for dry mouth don’t have that many others do is alcohol because this can exacerbate the issue. For some, simply switching to alcohol-free mouthwash can alleviate some of the dry mouth symptoms. 

One of the most common ingredients used to combat dry mouth is xylitol, which is a refined sweetener or sugar alcohol, which helps kill harmful bacteria and produce saliva. 

Types of mouthwash

When selecting the type of mouthwash, you typically have three choices: 

  • Liquid: This is the most common and the most popular type. It’s also the most effective at covering, moisturizing and soothing the entire mouth. 
  • Tablet: Chewable tablets are a good temporary solution when on the go to relieve dry mouth symptoms. 
  • Spray: Similar to tablets, sprays are good to use throughout the day but are not as thorough or effective as a liquid mouthwash.   

What to look for in a quality mouthwash for dry mouth


Mouthwashes come in a variety of flavors to both make them pleasant to use, and to leave your breath smelling fresh. However, since mouthwashes designed for dry mouth don’t contain alcohol, they often include natural ingredients to help trigger saliva production. This can impact the consistency and taste. So, if flavor is going to be an issue for you, be sure to check the reviews before purchasing. 


Some mouthwashes for dry mouth rely on natural enzymes and extracts instead of dyes or artificial flavors. Some of these natural ingredients can create a chunky texture. 

How much you can expect to spend on a mouthwash for dry mouth

On the low-end, you can find mouthwash for dry mouth for as low as $5, and you can spend over $30 for some of the best products. But most quality products can be found for between $20-$30. 

Keep in mind that if you find a product that you like and feel is effective, you might be able to take advantage of buying packs of two or more to cut down on the cost of individual products.
