Professional Dental Supplies has launched Gengigel (hyaluronic acid) dental gel and mouth rinse. The company says that in gingivitis and periodontitis, plaque enzymes break down the long chain structure of hyaluronic acid and this leads to oedema and inflammation. By using Gengigel, tissues are able to heal rapidly, it adds (retail price, gel 20ml £4.99, mouth rinse 150ml £6.99). The company says that it hopes to make the products available through pharmacies but currently they can be ordered directly from Professional Dental Supplies (tel 01480 471972).
