Dentures are full-mouth false teeth , which are used in old age (or after an accident in which the users' real teeth have all been knocked out) and also, when your teeth go bad because of certain ailments, to allow for a normal appearance and aid in chewing.
Problems with dentures include the fact that they often don't 'feel right' in the wearer's mouth and that they have a tendency to move around, thus requiring denture adhesive to hold them in place.
