I had gingivitis problems so my dentist always gave me free samples to manage this problem. No dentist has every mentioned this product so I called the company to see how long this product has been out. It went on the market last summer. Surprisingly, dental offices do not carry it. The company said you can order it directly online or phone. The price is $24.99 for a one month supply (one lonzenge per day) plus $5 shipping.
