I'm curious as to which is the better brand of mouthwash?

Not much difference: They are all about the same.

Personal preference: They are all good. Some have alcohol and some don't. There are some rx rinses as well. If concerned please consult with your dentist to see which would be best for your particular situation. Hope this helps.

Mouth rinses: First, for most individuals, mouth rinses are not an essential part of good oral hygiene and dental health. There are a zillion products out there....Some have alcohol and others don't, some have better antimicrobial effects than others, some claim tartar and plaque control, etc... There is no one generally accepted better brand or specific product. This should be discussed with your own dentist.
