You should not use denture adhesives -- powders or pastes that hold your dentures in place -- if you are allergic to adhesives. Also, if your dentures are loose, uncomfortable, or painful, you should not use denture adhesives, as they are not a substitute for properly fitting dentures. Visit your dentist regularly to make sure that your dentures fit between your gum and jaw correctly.
Make sure to take good care of your dentures and teeth. Poor oral hygiene and denture care can cause gum disease and infections.
