Dry Mouth? Clinically Proven Relief is Here!

Dry mouth, or xerostomia, is a common condition that affects millions of people. There are a lot of causes of dry mouth but the main thing that happens is the salivary glands don’t produce enough saliva or the saliva is of poor quality.

The good news is there is an easy fix to help relieve dry mouth symptoms – DrTung’s Herbal Toothpowder Tabs.

Yes, aging is a factor. But many medications and medical conditions can cause dry mouth. Lifestyle factors like smoking, alcohol, caffeine, and mouth breathing can also be a key factor. And here is one that most people don’t know about – toothpaste.

Most toothpastes contain ingredients that can worsen dry mouth such as sodium lauryl sulfate (SLS) and whitening agents like hydrogen peroxide.

Four months ago, I switched from a natural toothpaste to DrTung’s Herbal Toothpowder Tabs. It is a great product  formulated with time-honored Ayurvedic botanicals such as neem, cardamon, clove, miswak (toothpaste tree), and triphala, combined with mineral-rich cleansing agents.

Using the product, I noticed an even greater smoothness on my teeth and a “slippier” saliva. And I also noticed that I never experience dry mouth, even when I am outside for hours in the hot Arizona sun playing golf.

Now, a recent clinical study from the Istituto Stomatologico Toscano in Italy has confirmed the clinical benefit in dry mouth – no matter what the cause.

In the study, people brushing their teeth with one DrTung’s Herbal Toothpowder Tablet twice daily significantly improved multiple measures of dry mouth symptoms in just two weeks by dramatically improving salivary flow and pH, and other measures.

Conducted between December 2024 and March 2025, the study included 41 participants (average age ~60), nearly half of whom had chronic medical conditions such as diabetes, hypertension, and cardiovascular disease—groups at higher risk for dry mouth.

• Perceived dry mouth severity (0 = no symptoms, 10 = worst imaginable), dropped from 4.22 to 2.78 in just 15 days and nearly 88% of participants reported significant symptom improvement even if on medications linked to dry mouth.
• In those with very low saliva flow, 94% showed improvement. And 75% of participants with thick or frothy saliva saw improved consistency.
• The average saliva pH increased from 6.64 to 6.83 (p=0.027), moving closer to the optimal oral pH of 7.0 and 32% of participants reached the optimal pH of 7.0 by the end of the study.
• Over 85% of subjects showed improved saliva buffering capacity—important for protecting enamel and resisting pH fluctuations. 

These results are particularly meaningful for elderly individuals or those taking medications that reduce saliva production.

Unlike conventional mouthwashes or chemical-based products, DrTung’s Toothpowder Tabs offer a gentle, botanical-based solution with clinically demonstrated effectiveness for dry mouth.

Supercharged with herbal power it also cleans teeth, supports saliva balance, and bolsters the oral microbiome. Simply put, like the other oral health care products from DrTung’s, it is a better-for-you, eco-friendly product.
