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.

Very Helpful for Dry Mouth After Gastric Bypass
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
This mouthwash has been very helpful for dealing with dry mouth, especially with the body changes that can happen after gastric bypass surgery. It’s gentle, doesn’t burn like traditional mouthwash, and helps keep my mouth feeling hydrated and fresh. Pros Great for dry mouth: Provides noticeable relief and keeps my mouth feeling moisturized. Gentle formula: No strong burning sensation like alcohol-based mouthwashes. Fresh mint flavor: Clean taste that isn’t overpowering. Large bottle: The 33.8 oz size lasts a long time. Good for post-surgery changes: Works well for dryness that can happen after gastric bypass. Considerations The mint flavor is mild, which some people may prefer, but those who like a strong mint may find it subtle. Best results come from using it regularly. Best For People experiencing dry mouth Post-surgery dry mouth relief Nighttime mouth dryness Anyone wanting a gentle mouthwash without alcohol Final Verdict A great option if you struggle with dry mouth. It’s gentle, refreshing, and provides lasting relief. It has been especially useful during recovery after gastric bypass when dry mouth can be more noticeable.
