Best Mouthwash for Dry Mouth in 2026
Dry mouth (or xerostomia) is more than just an uncomfortable nuisance. According to the ADA (American Dental Association), saliva acts as a buffer that protects oral tissue against acids and helps maintain oral cleanliness, coating and protecting the mucosa from microbial and chemical injury. The Mayo Clinic lists increased plaque, tooth decay, and gum disease among the complications of not having enough saliva, and bad breath among the symptoms. The right mouthwash can’t replace saliva, but it can help keep your mouth comfortable, hydrated, and protected between dental visits. Because bad breath is one of those symptoms, many people also pair their rinse with the best mouthwash for bad breath.
We checked the options below against dry-mouth guidance from the ADA and the Mayo Clinic, each product’s ingredient list or drug label, and the makers’ own product pages to bring you this guide to the best mouthwash for dry mouth.
How We Evaluated
Before diving in, here’s how we approached this roundup. We looked at:
- Formulation: We prioritized alcohol-free formulas, since alcohol is known to further dry out oral tissues, according to the ADA.
- Key ingredients: We looked for humectants like xylitol, glycerin, and carboxymethylcellulose (CMC), which may help with moisture retention in the mouth.
- Fluoride content: Because people with dry mouth face elevated cavity risk according to American Dental Association guidance, fluoride content was a significant plus.
- Clinical guidance: We checked our criteria against the ADA’s and the Mayo Clinic’s dry-mouth guidance; the Mayo Clinic names Biotène Dry Mouth Oral Rinse and ACT Dry Mouth Mouthwash as examples of dry-mouth rinses.
- Flavor and tolerance: Alcohol-free doesn’t always mean pleasant. We favored mild and unflavored formulas and noted where a maker says its rinse doesn’t burn.
- Value for money: We considered bottle size, cost per ounce, and availability.

Why We Recommend It
The Mayo Clinic says mouthwashes designed for dry mouth, especially ones with xylitol, can be effective, and it names Biotène Dry Mouth Oral Rinse as an example. The current rinse is not enzyme-based: its listed ingredients start with water, glycerin, xylitol, and sorbitol, which Biotène describes as a mouth moisturizing system that soothes and lubricates. According to American Dental Association guidance on dry mouth management, products that mimic saliva can be beneficial for xerostomia relief.
It’s completely alcohol-free, with a refreshing mint flavor. Biotène’s listing says it provides immediate symptom relief, up to four hours of relief from dry mouth symptoms, and helps maintain a balanced pH in the mouth.
Key Features
- Alcohol-free formula
- Contains glycerin and xylitol in a moisturizing system Biotène says soothes and lubricates
- Refreshing mint flavor
- Available in a generous 33.8 oz bottle for roughly $10–$15
- Up to four hours of relief, per Biotène; directions say to use it whenever desired
Who It’s Best For
Anyone experiencing dry mouth caused by medication (antihistamines, antidepressants, blood pressure drugs), cancer treatment, or Sjögren’s syndrome will find Biotène a reliable daily companion. It’s also a solid starting point for anyone just beginning to address dry mouth symptoms.
Potential Downsides
Biotène does not contain fluoride, so if cavity protection is a top priority, you may want to pair it with a fluoride toothpaste or supplement with a fluoride rinse. Biotène also claims up to four hours of relief per rinse, so all-day or overnight dryness means repeat rinsing, or pairing it with a longer-lasting product.

2. Oral-B Dry Mouth Oral Rinse — Best for Long-Lasting Moisture
Oral-B Dry Mouth Oral Rinse
Best for: people who want a moisturizing rinse that Oral-B says relieves dry mouth symptoms for up to 6 hours
- Alcohol-free
- Xylitol, glycerin, cellulose gum, and sodium hyaluronate in its ingredient list
- Claims up to 6 hours of dry mouth symptom relief
- No fluoride, so pair it with a fluoride toothpaste
- +No added alcohol, artificial dyes, parabens, gluten, or SLS, per Oral-B
- +Claims up to 6 hours of dry mouth symptom relief, useful for overnight or workday dryness
- +Moisturizing Mint flavor that Oral-B says freshens breath
- −No fluoride in its ingredient list, so cavity protection has to come from your toothpaste
- −Sold as a 16 fl oz bottle, about half the size of the 33.8 fl oz Biotène bottle
Currently unavailable on Amazon (September 2026)
Why We Recommend It
Oral-B’s entry into the dry mouth category is formulated to provide moisturizing relief for up to six hours, according to the brand’s own product page. That kind of extended comfort can be meaningful for people who wake up with overnight dryness or who need relief that lasts through a workday. Its ingredient list, as posted by the retailer Hy-Vee, pairs glycerin and xylitol with cellulose gum and sodium hyaluronate, and contains no fluoride; Oral-B says the formula has no added alcohol, artificial dyes, parabens, gluten, or SLS.
Key Features
- Alcohol-free
- Xylitol, glycerin, cellulose gum, and sodium hyaluronate
- Claims up to 6 hours of dry mouth symptom relief
- Moisturizing Mint flavor
- No fluoride
Who It’s Best For
This one fits people whose dryness runs through a workday or the night, if the six-hour claim holds for them. It carries no fluoride, so anyone whose dentist has said dry mouth is raising their cavity risk should pair it with a fluoride toothpaste or look at the ACT Dry Mouth rinse below, which adds 0.02% sodium fluoride. For additional cavity defense, the best mouthwash for cavities has a dedicated roundup of the top fluoride rinses.
Potential Downsides
It contains no fluoride, so it does nothing for cavity risk on its own. It is also sold as a 16 fl oz bottle, about half the size of the 33.8 fl oz Biotène bottle above.
Availability, September 2026: Amazon lists this product as currently unavailable, with no restock date, at our September 18 read, so the buy button is off this card. The Biotène rinse above does the same moisturizing job and is in stock.
3. ACT Dry Mouth Anticavity Fluoride Mouthwash — Best for Cavity Protection
ACT Dry Mouth Anticavity Fluoride Mouthwash (Soothing Mint, 33.8 fl oz)
Best for: adults with dry mouth who have a history of cavities or have been told by their dentist they're at elevated decay risk
- 0.02% sodium fluoride, per its listing and ACT's DailyMed drug label
- Alcohol-free
- Soothing Mint flavor
- Designed specifically to address both dry mouth and cavity prevention
- +Pairs 0.02% sodium fluoride with a moisturizing base to address both dry mouth and cavity prevention
- +Alcohol-free with a soothing mint flavor
- +Adds fluoride protection that Biotène's rinse does not carry
- −Its 0.02% sodium fluoride is under half the 0.05% in ACT's plain Anticavity rinse
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
The Mayo Clinic names ACT Dry Mouth Mouthwash alongside Biotène as an example of a dry-mouth rinse, and ACT’s listing says it combines seven moisturizers with fluoride and xylitol. The combination of 0.02% sodium fluoride (the strength on its listing and on the DailyMed drug label for ACT’s 18 fl oz bottle of the same formula) with a moisturizing base makes it a sensible pick for patients whose dentists have flagged early-stage decay alongside dry mouth; if your dentist wants the stronger 0.05% daily rinse, that is ACT’s plain Anticavity line, not this bottle. According to the ADA, fluoride rinses may help with remineralization of weakened enamel, making this a particularly useful option for higher-risk individuals.
Key Features
- 0.02% sodium fluoride (its listing, and the DailyMed drug label for ACT’s 18 fl oz bottle of the same formula)
- Alcohol-free
- Soothing Mint flavor
- Designed specifically to address both dry mouth and cavity prevention
- Sold here as one 33.8 fl oz bottle
Who It’s Best For
Adults with dry mouth who have a history of cavities or have been told by their dentist they’re at elevated decay risk. Also well-suited for older adults, who are statistically more likely to experience dry mouth as a side effect of multiple medications.
Potential Downsides
ACT Dry Mouth carries 0.02% sodium fluoride, under half the 0.05% in ACT’s plain Anticavity rinse. It is also a fluoride drug rinse with a schedule: the DailyMed label for ACT’s 18 fl oz bottle of the same formula directs twice-daily use for one minute, while the Directions field on this 33.8 fl oz listing gives only a 30-second to 1-minute swish and no frequency (ACT’s FAQ on the same listing says 1-2 times daily). Either schedule asks more of your routine than Biotène’s whenever-desired swish, so follow the bottle you buy.

4. TheraBreath Dry Mouth Oral Rinse: Saliva-Stimulating Enzymes, per TheraBreath
TheraBreath Dry Mouth Oral Rinse
Best for: people who want an alcohol-free rinse with enzymes and a flower extract that TheraBreath says help stimulate saliva
- Alcohol-free
- Contains xylitol and naturally sourced salivary enzymes
- Enzymes and a flower extract to help stimulate saliva, per TheraBreath
- Dentist formulated, per TheraBreath
- +Salivary enzymes and a flower extract that TheraBreath says help stimulate saliva production
- +Alcohol-free and non-burning, per TheraBreath, sweetened with xylitol
- +Non-burning enough for people who react badly to conventional mint rinses
- −Contains no fluoride
- −About 55 cents an ounce in this 2-pack, against about 32 cents for the 33.8 fl oz Biotène bottle
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
TheraBreath started as a bad-breath brand (the brand’s anticavity listing says Dr. Harold Katz created it in 1993), but this dry mouth rinse works on the dryness itself: TheraBreath says its naturally sourced salivary enzymes and a floral jambu extract help stimulate saliva production and produce a tingling sensation. Unlike TheraBreath’s anticavity rinse, its ingredient list has no sodium chlorite, the oxygenating compound the brand says fights bad breath bacteria. The breath link is indirect but real: the Mayo Clinic lists bad breath among dry mouth’s symptoms and says saliva makes bacteria less harmful. Complementing it with the best toothpaste for bad breath can further reduce odor-causing bacteria at every brushing. And if you’re deciding between TheraBreath’s own bottles, the full lineup comparison breaks down all six formulas by problem.
Key Features
- Alcohol-free
- Contains xylitol and naturally sourced salivary enzymes
- Enzymes and a flower extract to help stimulate saliva, per TheraBreath
- Mild, non-burning formula
- Dentist formulated, per TheraBreath
Who It’s Best For
People who want a rinse aimed at saliva itself: TheraBreath says its enzymes and flower extract help stimulate saliva production. Also worth a look if conventional mouthwashes burn: TheraBreath says the alcohol-free formula doesn’t burn.
Potential Downsides
TheraBreath Dry Mouth does not contain fluoride. At about 55 cents an ounce in this 2-pack, it also costs noticeably more than the 33.8 fl oz Biotène bottle at about 32 cents.

5. CloSYS Ultra Sensitive Mouthwash — Best for Sensitive Mouths
CloSYS Ultra Sensitive Mouthwash
Best for: people with sensitive mouths, and anyone who has found that other mouthwashes cause burning or irritation
- Unflavored base with optional flavor drops
- pH-balanced formula
- Alcohol-free and sulfate-free
- Dye-, triclosan-, and gluten-free, per CloSYS
- +Unusually gentle: unflavored, alcohol-free, sulfate-free and pH-balanced to minimize irritation
- +CloSYS calls it gentle enough for the most sensitive mouths; ask your care team first if you have mouth sores or are in cancer treatment
- +Optional flavor drops and an optional fluoride version available
- −Unflavored version may feel unusual if you're used to a mint-fresh sensation
- −Sold here as a two-bottle pack, about 40 cents an ounce against about 32 cents for Biotène
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
CloSYS takes an unusually gentle approach to oral hygiene. Its Ultra Sensitive formula is unflavored by default (you can add the included flavor drops to taste), alcohol-free, and pH-balanced to be minimally irritating to soft tissue. CloSYS describes the formula as “as gentle as water” and free of dyes, sulfates, triclosan, alcohol, and gluten, and calls it gentle enough for the most sensitive mouths. If you have mouth sores or oral mucositis from cancer treatment, ask your care team before adding any rinse.
Key Features
- Unflavored base with optional flavor drops
- pH-balanced formula
- Alcohol-free and sulfate-free
- Optional fluoride version available
- Dye-, triclosan-, and gluten-free, per CloSYS
Who It’s Best For
People with sensitive mouths, and anyone who has found that other mouthwashes (even “gentle” ones) cause burning or irritation. If you are in cancer treatment or have mouth sores, check with your care team first.
Potential Downsides
The unflavored version may feel unusual if you’re accustomed to a mint-fresh sensation. It also costs more per ounce than Biotène (about 40 cents against about 32 cents), and this listing is a two-bottle pack.

6. SALIVEA Dry Mouth Mouthwash — Best for Enzyme-Based Everyday Relief
SALIVEA Dry Mouth Mouthwash
Best for: People looking for a gentle, enzyme-based dry mouth rinse that mimics the natural protective properties of saliva
- Contains natural salivary enzymes (lysozyme, lactoferrin, lactoperoxidase)
- Alcohol-free
- Xylitol-sweetened, with aloe vera
- Soothing mint flavor
- +Uses natural salivary enzymes (lysozyme, lactoferrin, lactoperoxidase) to mimic healthy saliva
- +Alcohol-free and xylitol-sweetened; the Mayo Clinic says xylitol products may help prevent cavities
- +Gentle, with what SALIVEA calls a soothing, soft mint formula
- −SALIVEA's own site sends shoppers to Amazon to buy it
- −About 91 cents an ounce for the 16 fl oz bottle, the highest per-ounce price of the rinses here
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
SALIVEA takes a different approach to dry mouth relief by using a blend of natural salivary enzymes (including lysozyme, lactoferrin, and lactoperoxidase) that mimic the protective compounds found in healthy saliva. Rather than just coating your mouth with moisture, the formula is designed to support the oral environment the way saliva naturally does. It’s alcohol-free and includes xylitol, which the Mayo Clinic says may also help prevent cavities, a point that matters for dry mouth sufferers who are at elevated risk of tooth decay.
Key Features
- Contains natural salivary enzymes (lysozyme, lactoferrin, lactoperoxidase)
- Alcohol-free
- Xylitol-sweetened, with aloe vera
- Soothing mint flavor
- No fluoride, so keep a fluoride toothpaste in the routine
Who It’s Best For
People looking for a gentle, enzyme-based dry mouth rinse that goes beyond simple lubrication. Particularly well-suited for anyone who wants the salivary enzymes that Biotène’s current rinse does not list.
Potential Downsides
SALIVEA is a smaller brand than Biotène or ACT, and its own site sends shoppers to Amazon to buy. At about 91 cents an ounce for 16 fl oz, it is also the most expensive rinse here per ounce.

Buyer’s Guide: What to Look For
Choosing the right mouthwash for dry mouth doesn’t have to be overwhelming. Here are the key factors worth considering before you buy.
Always Go Alcohol-Free
This is non-negotiable. The ADA’s dry mouth guidance lists alcohol, including alcohol-containing mouthrinses, among the irritants to avoid, and the Mayo Clinic says plainly not to use a mouthwash that contains alcohol. Every product on our list is alcohol-free for this reason.
Look for Humectants and Moisturizing Agents
Ingredients like glycerin, xylitol, carboxymethylcellulose (CMC), and aloe vera may help with moisture retention in oral tissues. These are the workhorses of a good dry mouth rinse.
Consider Adding Fluoride
Because saliva naturally helps remineralize enamel and buffer acids, people with dry mouth lose that protective effect. According to the ADA, fluoride may help with remineralization and cavity prevention, and the Mayo Clinic notes that saliva helps prevent tooth decay by washing away sugar and food particles, and lists tooth decay among dry mouth’s complications. If your dentist has flagged decay risk, opt for a rinse with sodium fluoride. Plaque buildup accelerates without adequate saliva: our guide on how to remove plaque from teeth explains what you can do at home to compensate.
Check the pH
Saliva normally helps keep the mouth at a neutral pH, according to the ADA, so a rinse that is itself close to neutral does not add acid to a mouth that is short of that buffer. Biotène’s listing says its rinse helps maintain a balanced pH, and CloSYS describes its Ultra Sensitive formula as pH balanced.
Match It to Your Root Cause
Dry mouth from medication behaves differently than dry mouth from Sjögren’s syndrome or from mouth-breathing. Talking to your dentist or pharmacist about the underlying cause can help you select the right product; and rule out whether you need a prescription-strength saliva substitute. Chewing on xylitol gum between rinses is another common way people stimulate saliva flow throughout the day.
FAQ
Q: Can mouthwash cure dry mouth? A: No mouthwash cures or treats the underlying cause of dry mouth. Rather, a good dry mouth rinse may help with symptom relief—soothing oral tissues and providing temporary moisture. The ADA lists identifying the cause among the goals of treating dry mouth and notes that switching some medications can reduce their drying effect, which is a conversation for your doctor.
Q: How often should I use mouthwash for dry mouth? A: Follow the label, because they differ. Biotène’s directions say to use it whenever desired and TheraBreath’s say as needed, while the DailyMed label for ACT’s 18 fl oz Dry Mouth rinse, a fluoride drug rinse, directs twice a day (the Directions field on the 33.8 fl oz listing we link gives no frequency; ACT’s FAQ on that listing says 1-2 times daily). We’d suggest using a non-fluoride rinse after meals and before bed as a starting routine, and adjusting based on how your mouth responds.
Q: Is it safe to swallow dry mouth mouthwash? A: Most dry mouth rinses are formulated to be rinsed and spat out, not swallowed. While small accidental amounts are generally not harmful, habitual swallowing (especially of fluoride-containing rinses) is not recommended, particularly for children. Always follow the label instructions.
Q: Why does regular mouthwash make my dry mouth worse? A: Many conventional mouthwashes contain alcohol, which is a drying agent. The ADA notes that alcohol can be drying and lists alcohol-containing mouthrinses among the irritants people with dry mouth should avoid. Switching to an alcohol-free formula is one of the simplest and most impactful changes you can make.
Q: Can dry mouth mouthwash replace saliva? A: Not fully. Saliva is a complex fluid that contains enzymes, antibodies, and minerals that no rinse can fully replicate. However, dry mouth rinses may help with lubrication, comfort, and basic oral hygiene support in between your natural saliva production. For severe cases, your dentist may recommend a prescription saliva substitute. For relief that lasts longer between rinses, our best lozenges for dry mouth roundup covers slow-dissolving options built to keep working over longer stretches, including overnight.
Q: Should I use a dry mouth mouthwash if I’m on chemotherapy? A: Possibly, but check with your oncologist or dentist first. Some chemotherapy patients develop oral mucositis, which requires an especially gentle approach. An unflavored, alcohol-free rinse such as CloSYS Ultra Sensitive is one to ask them about, but clinical guidance should come from your care team.
Our Methodology
We evaluated products for this roundup using a structured review process. We reviewed ingredient lists for key dry mouth actives (humectants, enzymes, fluoride), read the DailyMed drug label for the fluoride rinse and each maker’s own product page, and checked our picks against dry-mouth guidance from the American Dental Association and the Mayo Clinic.
We also considered accessibility (including price, bottle size, and retail availability) to ensure our picks are realistic for everyday shoppers, not just those in major metro areas with specialty pharmacy access.
