I just got my uppers and bottom dentures a week ago.
That’s a great question! It honestly depends on your personal preference. Many people swear by one or the other, or some combination of both. It may take some time to determine what results in the best hold for you. Many of the posts in the forums mention what other people have tried, so check those out and see what you find!
I personally like Fixodent for days where I only want to wear my denture for under 10 hours. If I want to wear it for over 10 I will use Secure denture adhesive It seems to be able to hold longer, but that is an issue on days where you dont want to keep them in that long. Im referring to the adhesives. I have not tried any powder or paste yet.
