How to get full and partial dentures out of mouth

I just had most of my teeth extracted yesterday and had immediate full dentures put in on the top and partial dentures put in on the bottom.  I returned to my regular dentist today and he took out my upper dentures, put denture glue on them and stuck them back in my mouth.  It took me forever to get them out tonight.  

Now, I'm having trouble getting the partial dentures off of my bottom teeth.  I've rinsed my mouth with salt water as directed but had to leave the bottom partials in to do it.  I don't see my dentist again until Monday and his office is closed over the weekend.

Can someone give me some helpful advice?

Thanks,
