When dentures feel loose in the mouth, a fixative can be used to help stable them. Fixatives can be bought from a pharmacy and applied by yourself. Dentures should be cleaned thoroughly, either with warm water or a specialist denture toothpaste. Shake off excess water. Apply the fixative, however, using too much fixative may result in ‘oozing’. Using smaller amounts may provide better adhesion. The amount used will vary between dentures. A good fixative applied in the morning should last all day!
