Best Dry Mouth Products (Full Review)

Dentist Tested and Reviewed

Dry mouth, or xerostomia, refers to the inability of your salivary glands to produce adequate saliva to keep your mouth moist.

This condition is severely problematic for patients in all aspects of life.

For example, patients cannot taste and break down their food properly.

Also, their oral tissue may become dry and irritated because of the lack of moisture.

As an experienced dentist with years of experience, I’ve tested and evaluated 300+ dental products. I strive to find the best products for achieving excellent oral hygiene, so let’s take a closer look at the Best Dry Mouth Products from a dentist’s perspective.

Dry Mouth (Xerostomia) Overview

Xerostomia can occur due to medication side effects, various medical conditions, autoimmune diseases, or head and neck radiation therapy.

Saliva is vital for many reasons, including preventing tooth decay. In addition, your mouth needs to maintain a balanced pH to minimize harmful bacteria growth.

If you have a dry mouth, the oral pH becomes more acidic, cultivating a more favorable environment for bacteria growth and proliferation. After this occurs, the acid attack may damage the teeth and cause cavities.

Dry Mouth Symptoms

• Bad breath
• Dry or grooved tongue
• Difficulty chewing, speaking and talking
• Thick and stringy saliva
• Dryness in mouth
• Altered sense of taste
• Dry or sore throat
• Problems wearing dentures

Evaluation Criteria

I (Dr. Hannan) tested each product for 7-14 days, detailing its pros and cons, and rated it from 1 to 5 in four key areas.

• Effectiveness: Does the oral rinse treat the advertised need? How effective were the results?
• Comfort: Are you able to swish for recommended time? Did it sting or burn? How did the mouth feel afterwards?
• Taste: How was the overall taste? Was it tolerable? Did it alter your sense of taste?
• Likeability: Was it enjoyable to use? Does the product desire unrealistic expectations?

1. Best Overall | Biotene Dry Mouth Moisturizing Spray

Dentist Review

Biotene Dry Mouth Moisturizing Spray is convenient and portable to carry in a pocket or purse.

It was effective at immediately relieving dry mouth and soothing irritated gum tissue.

Also, it worked well at freshening breath and coated all surfaces with a lubricant-like solution that also seemed to prevent recurring periods of dry mouth.

No stinging, burning or altered sensation was noted; however, we would have desired more of a mist spray rather than a stream spray.

Best on-the-go dry mouth moisturizing spray.

2. Best Post-Meal | ACT Dry Mouth Moisturizing Gum

Dentist Review

ACT Dry Mouth Moisturizing Gum was highly effective at stimulating saliva production and immediately relieved dry mouth.

The soothing mint flavor is exceptional and not too strong or overpowering. It was comfortable to chew and gentle on sensitive gums, and Xylitol is an added bonus for preventing tooth decay.

Some individuals may prefer other methods to relieve dry mouth; however, we were impressed overall.

Best saliva-stimulating, dry-mouth gum.

3. Best Xylitol | ACT Dry Mouth Lozenges

Dentist Review

ACT Dry Mouth Lozenge was extremely sweet and immediately quenched dry mouth.

There was no burning or irritation. However, slight tingling of the tongue was observed. The sweet-mint flavor was perfectly balanced and provided lasting fresh breath.

After the lozenge dissolved, a slight taste alteration quickly subsided. Overall we were impressed with its effectiveness; however, other products provided greater dry mouth relief.

Best sweet-mint, dry-mouth lozenge.

4. Best Fruity | TheraBreath Dry Mouth Lozenges

Dentist Review

TheraBreath Dry Mouth Lozenges effectively relieved dry mouth. The mandarin-mint flavor was unique and freshened the breath with a fruit-flavored aftertaste.

We anticipate that some individuals may prefer a stronger mint flavor for added freshness. Also, the lozenge tingled the tongue, creating a fun experience for the user.

However, we realize that some individuals may be turned off by this unique sensation and prefer other means of relieving dry mouth. Lastly, the lozenges are individually packaged for convenience and portability.

Best fruit-flavored, dry mouth lozenge that tingles the tongue.

5. Best Mint-Free | OraCoat Dry Mouth XyliMelts

Dentist Review

OraCoat Dry Mouth XyliMelts adhered firmly to the oral tissue. It steadily allowed saliva to interact and relieve dry mouth over time.

Initially, it was odd having a melt adhered to the inside of the cheek; however, the effectiveness made it worth it. A bonus was using it at night when dry mouth can be problematic and bothersome.

Unfortunately, we were disappointed with the lack of flavor and fresh breath compared to other products. Lastly, the tan adhesive side was slightly bitter when it dislodged from the gum tissue.

Best stick-on melt that relieves dry mouth during the night.

6. Best Toothpaste | Biotene Dry Mouth Fluoride Toothpaste

Dentist Review

Biotene Dry Mouth Fluoride Toothpaste was exceptionally comfortable to use.

The gentle, non-irritating formula was evident; however, we would have appreciated more significant dry mouth relief. The fresh-mint flavor was perfectly balanced and freshened my breath for many hours.

This product is highly recommended for patients sensitive to Sodium Lauryl Sulfate.

Best dry mouth, non-irritating fluoride toothpaste.
