Helps With Dry Mouth, Tastes Great and Easy to Keep On Hand
Size: 27 Count (Pack of 1), Size: 27 Count (Pack of 1)
Update: I have already repurchased more! I love the taste and they work so well with a great taste.
I’ve been dealing with dry mouth lately, especially at night, and these Biotene Dry Mouth Lozenges have been really helpful. They dissolve slowly and help keep my mouth feeling more comfortable without being overly sweet or strong.
The mint flavor is light and refreshing, which I appreciate because some lozenges can taste too medicinal. These are gentle and easy to use throughout the day or before bed if dryness is bothering me.
The packaging is also convenient to keep in a bag or on a bedside table. I like that the lozenges are sugar-free and individually sealed in the blister pack so they stay fresh.
I included a photo of the lozenge in my hand so you can see the size and what it looks like out of the package, along with photos of the box and blister pack for reference.
These are simple, effective, great taste and a good option to keep on hand if you deal with dry mouth.

Would continue to buy again
Size: 27 Count (Pack of 1)
Purchased twice. I wish they made these bigger. Moisturizing mouth well and flavor is pleasant and long lasting. I have Sjogrens and suffer with dry eye and mouth. These work better than regular lozenges.
