Chx Plus nature. Dentists have been prescribing chlorhexidine for almost 70 years and for good reason: it works! In addition to chx DIGLUCONATE, perio Plus+ contains natural bioflavonoids extracted from bitter oranges (citrus aurantium amara): citrox. The bioflavonoids of citrox have powerful intrinsic antibacterial properties. Combining citron and chx - perio Plus+ proves to be exceptionally effective. Perio Plus+ tastes good, thanks to citron and the flavouring, this product does not have any impact on your sense of taste. Hyaluronic acid is recommended especially after operations. It regulates moisture levels, promotes cell growth and speeds up regeneration. Perio Plus+ or other chx products should be used at your dentist's recommendation.
