It is both adhesive like glue and prevents the "hits" of artificial dentures on the gums, while filling any gaps between them, so that it adheres even better. The only negative thing I have is that while it used to come in packs of 20, now it comes in packs of 15, but still at the same price...

From the corresponding ones that are available in Greece and Spain, it is the best. It applies like an intermediate cushion and apart from good grip, it also offers protection of the gums from "hits" of the dental alignment.
