For good oral hygiene
Color: Pink
For people who, like me, have undergone oral surgery, this works incredibly well—and for those who haven't, it works just as well, as it helps ensure that nothing gets trapped between the teeth. It is an excellent complement to your oral hygiene routine.

Soothing, moisture-locking oral coat that eliminates morning dryness without burning your mouth
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
Standard alcohol-based mouthwashes give a powerful blast of burning freshness, but they completely dry out your tissues and make a lack of natural saliva much worse. Biotene Dry Mouth Oral Rinse fixes this issue entirely by skipping the harsh astringents. It uses a specialized mouth-moisturizing system packed with hydrating humectants like glycerin, xylitol, and sorbitol. This combination creates a slippery, lubricating layer over your gums and cheeks that mimics your natural saliva to keep your mouth comfortable and damp.
The daily utility of this formula is perfect if you struggle with persistent stickiness, difficulty swallowing dry foods, or a scratchy throat. It provides immediate relief that keeps working for up to four hours, soothing sensitive oral tissue and actively fighting the bacteria that cause chronic bad breath. The gentle, sugar-free fresh mint flavor leaves you feeling genuinely clean and maintains a healthy, balanced pH level in your mouth to protect your teeth from potential cavities. It is a fantastic, non-burning formula to use right before bed or throughout the day to completely wash away that uncomfortable, parched feeling and wake up with lasting comfort.
