This mouthwash works very well. It leaves my mouth feeling fresh for hours and protects my teeth from plaque. I really have noticed a decrease in the amount of plaque I accumulate since using this. The issue is, however, is that the "guard" works too well! For hours after I use this, I cannot eat or drink anything without it tasting absolutely disgusting because this product lingers forever to protect your teeth. It doesn't just attach to your teeth, but your tongue and taste buds also. Therefore, I can only recommend this product if you only plan on using it at night after you're completely done eating or drinking for the day. I use a different mouthwash in the morning because otherwise, I wouldn't be able to eat or drink anything besides water until dinnertime.
