Best Mouthwash for Dry Mouth: What to Look For

By Lovik Mirzaeian, DDS. Updated October 2026.

The best mouthwash for dry mouth is one that is alcohol-free and made specifically to moisturize, ideally with xylitol and, if you are prone to cavities, fluoride. Regular mouthwashes that contain alcohol can make a dry mouth feel worse, so check the label before you buy.

Below is what to look for, some well-known dry mouth rinses, how to use them, what causes dry mouth in the first place and when it is worth seeing a dentist.

What to Look For in a Dry Mouth Mouthwash

Alcohol-free

This is the most important point. Alcohol can dry out the tissues of your mouth further, which is the opposite of what you need. Look for “alcohol-free” or “zero alcohol” on the front of the bottle.

Moisturizing ingredients

Dry mouth rinses usually contain ingredients such as glycerin, xylitol, sorbitol or cellulose gums that coat and moisten the soft tissues. They do not make your glands produce more saliva on their own, but they can make your mouth feel more comfortable for a while.

Xylitol

Xylitol is a sugar substitute that cavity-causing bacteria cannot use. It is common in dry mouth products and in sugar-free gum, and chewing xylitol gum can help stimulate saliva.

Fluoride

Saliva protects teeth from decay, so people with chronic dry mouth tend to get more cavities. A fluoride rinse adds some of that protection back. Ask us whether a fluoride rinse makes sense for you.

Well-Known Mouthwashes for Dry Mouth

These are widely available alcohol-free rinses made for dry mouth. Formulas and sizes change, so always check the current label for ingredients.

TheraBreath Dry Mouth Oral Rinse

An alcohol-free rinse sweetened with xylitol, designed to moisturize and freshen breath.

Biotene Oral Rinse

One of the most familiar dry mouth brands. Alcohol-free, with xylitol, and made to soothe and moisturize dry tissues.

ACT Dry Mouth Mouthwash

An alcohol-free rinse that also contains fluoride, which makes it a good fit if you are prone to cavities as well as dry mouth.

Colgate Hydris Dry Mouth Mouthwash

An alcohol-free rinse designed to help keep a dry mouth moist.

Store-brand dry mouth rinses with similar ingredients can work just as well. What matters is that the rinse is alcohol-free and feels comfortable for you. For a broader look at whether you need a rinse at all, read do you actually need mouthwash.

How to Use a Dry Mouth Rinse

• Follow the directions on the bottle, which usually means swishing for 30 to 60 seconds.
• Use it after brushing and before bed, when dryness tends to be worst.
• Avoid eating or drinking for a short while afterwards so the rinse can do its job.
• Keep sipping water through the day. A rinse helps, but it does not replace hydration.

Other Ways to Relieve Dry Mouth

A rinse works best as one part of a routine. These habits help most people:

• Sip water regularly through the day and keep a glass by the bed.
• Chew sugar-free gum or suck on sugar-free lozenges, ideally with xylitol, to get saliva flowing.
• Run a humidifier in the bedroom at night if you wake up with a dry mouth.
• Cut back on caffeine and alcohol, which can both make dryness worse.
• Breathe through your nose where you can, especially during exercise and sleep.
• Brush twice a day with a fluoride toothpaste, since saliva is no longer doing as much to protect your teeth.
• Ask your pharmacist about over-the-counter saliva substitutes, gels or sprays if a rinse alone is not enough.

If a medication seems to be the cause, do not stop taking it on your own. Talk to the doctor who prescribed it, since there may be an alternative or a dose change that helps.

What Causes Dry Mouth?

Dry mouth happens when your salivary glands do not make enough saliva. Common causes include:

• Medications, including many for blood pressure, allergies, depression and anxiety.
• Not drinking enough water.
• Breathing through your mouth, especially at night.
• Smoking, vaping, alcohol and a lot of caffeine.
• Medical conditions such as diabetes and Sjögren’s syndrome, and treatments such as radiation to the head and neck.

If your mouth is driest first thing in the morning, see why your mouth is dry when you wake up. For quick relief tips, read the fastest ways to ease dry mouth. The American Dental Association’s patient site also has a clear overview of dry mouth.

Could sleep apnea be behind it?

Waking up with a very dry mouth can be a sign of mouth breathing during sleep, which is common with snoring and sleep apnea. If you also snore loudly or wake up tired, mention it at your visit. Our Clovis office offers custom oral appliances for snoring and sleep apnea.

When to See a Dentist About Dry Mouth

Book a visit if dry mouth lasts more than a few weeks, if rinses and water are not helping, or if you notice new cavities, sore spots, a burning feeling or trouble swallowing. Long-term dry mouth raises your cavity risk, so regular exams matter more than usual. We can check your teeth, look at possible causes and recommend products or fluoride treatment that suit you.
