Gengigel is a medical device containing high molecular weight hyaluronic acid obtained by a biotechnological manufacturing process which guarantees a high level of purity. Its formulation is specifically created in order to resemble that of the hyaluronic acid found in normal gingival tissue. The application of hyaluronic acid provides a periodontal tissue/fluid balance with accelerated healing and repair functions by preventing the deficiency of natural gingival hyaluronic acid and enhancing its effects.
