I saw a question on this topic posted either here in the Pipe Forum or on another board, but as a denture wearer, I thought that I would chime in. Due to an auto accident, and being an over 45 playing full-check hockey, I am now the proud owner of dentures top and bottom. Initially, I will explain what the dentures cover and then how they affect taste. I have done taste tests with identical cigars with the dentures in and out. The easy one is lower dentures: they only cover the lower gums and have no effect on taste. The upper dentures cover most of the upper palate and I have found that the upper palate does contribute to the taste of a cigar almost as much as the tongue does. I have discovered tastes on cigars with my plate removed that I would never taste with that hunk of plastic covering the roof of my mouth. I will give you an example with 2 cigars that most of you have smoked: Sancho Panza Double Maduro Cervantes, and Maria Mancini Magic Mountain. If I had never tried these without removing my upper plate, I never would have smoked them again. There were spices and coffee and chocolate tastes that I would never have noticed. I would have been just as well off as smoking cigarettes or White Owl Grapes just for the sake of having smoke entering my mouth and leaving. I am sure that there are other folks wondering about this and I hope this helps. Paul
