I think it is really helping me. The regular rinse is $6-7 for 16 ounces, while the more potent rinses(periodontal, orthodontal) are around $10-16 for 16 ounces. Only a small amount(perhaps half an ounce?) is used at a time. You could start with the regular rinse, and if you feel it is helping then consider using one of the stronger rinses. That is what I did. I started with the alcohol free one, then later got the periodontal.
