Maybe your gums have shrunk, and you need to get a new plate. I use both the powder and paste for upper and partical lower. I never have to re-apply the powder to the upper but need to re-apply to the lower before and after I eat sometimes as many as 6 times a day. I am in the process of getting a new lower partinal since my gums have shrunk. - hate getting old hate not having my own teeth, just have to live with it
