Dr. Harold Katz created the TheraBreath formula in 1993 for his own family. That's why our kids products contain no artificial dyes, no parabens or alcohol, and are vegan and gluten free. We believe your child's mouthwash should only contain what's truly needed and nothing else. With that in mind, TheraBreath for Kids contains a sodium fluoride active ingredient to help support strong, healthy teeth and reduce the formation of cavities. It's the same sodium fluoride the dentist uses for your child's fluoride treatment. Our alcohol-free formula doesn't burn or irritate and works instantly. We’re so confident in the effectiveness of TheraBreath Oral Rinses that we back them up with our 100% guarantee. If you're not satisfied, contact us within 30 days of purchase for a full refund.
