If you are one of 10% of people who have dry mouth, a common condition that's officially known as "xerostomia," brushing your teeth may exacerbate your symptoms and cause further irritation if you aren't using the right toothpaste. That's why, according to dentist Dr. Lewis Chen, DDS, FICOI, FIADFE, of Advanced Dental Group of Hoboken, the best dry mouth toothpastes contain ingredients that help cultivate a healthy level of saliva and are notably absent of ingredients known to exacerbate dryness. Plus, he adds, people with dry mouth should also avoid toothpaste with sodium lauryl sulfate (SLS), as that's another ingredient that can further increase dryness.
"Key ingredients to help someone tackling dry mouth would be sorbitol, xylitol, and fluoride," explained Dr. Chen, who is also the co-founder of Beam Street. "Sorbitol and xylitol are carbohydrates that bacteria cannot process to harm teeth and because of this, these compounds help stimulate saliva to create a moist oral environment. Fluoride is another key ingredient that helps manage the subsequent outcomes for those experiencing xerostomia by reducing the rate of demineralization and increasing remineralization of the tooth."
Dr. Chen points out that there are some ingredients to watch out for, as well. Specifically, SLS and alcohol can be irritating if you already have dry mouth and may even further increase oral dryness.
Now that you know what ingredients to look for and which to skip, take a look at the best dry mouth toothpastes below, all of which are highly rated by Amazon reviewers with xerostomia.

Helpful review: “I am always plagued with a very dry mouth. I can supplement that problem in the daytime, but at night, it is almost impossible. I wake up during the night with such a dry mouth that sometimes I find it stuck together! So, I tried this mouthwash, and I use it as directed twice a day. It gets me through the night without having to wake up and find water for my dry mouth.”
Also Consider: These Saliva-Stimulating Tablets That Melt In Your Mouth
Another solution for dry mouth that's also very highly rated on Amazon (with a 4.6-star rating after 2,400 reviews) are these xylitol-infused OraCoat XyliMelts, which several fans mentioned are very effective at keeping their mouth moisturized throughout the night (though they are safe for daytime as well).
To use, stick one or two of the oral tablets on a comfortable spot along your upper or lower gum line and then let them gradually dissolve on their own. A few users reported that the application will likely take some trial and error, but point out that you will know it's locked in place because it shouldn't budge. "If it comes loose, you either didn't have a good spot or it isn't wet enough to adhere," writes one. You'll get about four to eight hours of coverage from one dose, and you can choose from three flavors — mild mint (pictured), slightly sweet, or sweet cinnamon.
Helpful review: "These are better than the rest on the market in my opinion. The others are 'huge' in comparison to these. The taste is mild and enough for me. I used get dry mouth from my CPAP machine while I’m sleeping, not anymore."
