This is a particularly dangerous myth. Dentures usually do not require the use of any adhesives for a secure fit. In an emergency, denture adhesives can be used to keep the dentures stable until you see your Denturist, but prolonged use can lead to tissue irritation and cause bone loss in the ridges. If your dentures begin to feel loose, or cause pronounced discomfort, see your Denturist immediately. There are many options available now to help ensure that your dentures fit well without the use of adhesives.
