They work but you have to stick with it
They do absolutely make a difference especially if you follow instructions and brush your teeth do your mouthwash and then apply one but I used to A-day as a smoker to actually make a difference and even then after a month of doing it I feel like I'm just gonna have to order more but I am going to order more I don't know if it will ever fully fix the problem but it does make a difference it at least make sure I'll feel cleaner... I probably won't be ordering them from Amazon again though found them for cheaper on the actual website
