Caution: Contains shellfish derivatives. Chitosan is derived from the shells of shrimp and other hard crustaceans. Most shellfish allergies are caused by a muscle protein tropomyosin.

Those who suffer from a shellfish allergy should consult a qualified medical professional about use of Prisyna products and potential allergen testing.

Our family dentist recommended Synedent because of its amazing healing performance. My husband who has battled bad breath found it to do a terrific job for halitosis. Yes we are totally convinced that Synedent is a superior product and does much more for oral hygiene.

I’ve been using Synedent for a few years now and honestly can’t live without it. I never use regular mouth washes or rinses due to all the chemicals and horrid taste. Your product on the other hand not only tastes great, but really does leave my mouth feeling clean and fresh and not like I’ve scrubbed it out with Pine-Sol! I really can tell that it removes the plaque film and it brightens my breath as well. Thanks again for a great product!
