Love this stuff

I use this every time I brush my teeth and I believe it's the reason why I always have good checkups at the Dentist.

Thank you for the feedback! We love to hear it. <3

Debra Autry (Oklahoma City, OK)
Great product

I really like this has a light clean feeling.

Our proprietary bad breath-fighter Oxygene® works on contact to safely eliminate odors caused by bacteria. No other dental products have it! Thanks for the 5 stars. :)

Mint flavored was substituted. Have not used it yet.

Richard R Anderson (Kernersville, NC)
Oxyfresh is the best!

I use my mouthwash for something besides its intended purpose and my dentist has given it a real compliment. She says my night guard is the cleanest she had ever seen!

Laureetta Dorsey (Hollywood, FL)
Cavity Protection Mouthwash

Excellent product. I love the effect that I have since this product. It’s great !

Catherine Marchant (Brookline, MA)
Mild in flavor, easy to use

Will find out how effective it is as protection against cavities after using for next 3 months

Pam (Martinsville, VA)
Fresh taste

I have been using Oxyfresh toothpaste for a little while and decided to add this mouthwash. It has a really fresh taste...not overpowering, but just leaves your mouth feeling clean. I plan to stop getting those nasty fluoride treatments at the dentist and just use this fluoride rinse from here on out.

Terry James (North Hollywood, CA)
Dentist approved

I've been using this product for several years, but only in the evening. My dentist suggested I use twice a day and it appears the plaque buildup has reduced

Violetrose (Scotch Plains, NJ)
Great product

I am satisfied with this product. I wish that this was available when I was young.
