At a glance
Summary
This mouthwash contains beneficial ingredients like xylitol, which helps reduce cavity-causing bacteria, and sodium bicarbonate, which acts as a gentle abrasive. However, the presence of sucralose, an artificial sweetener that can disrupt gut microbiota, slightly detracts from its overall safety profile. The formula is free from alcohol and other major irritants, making it a relatively safe choice for oral care.
