Summary
This oral rinse 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, is a concern due to its potential impact on the gut microbiome. The product is processed, which limits its score despite the inclusion of some positive ingredients.
