As with any problem, there are several possibilities. If the plastic is digging into the vestibule and is not on the ridge itself, typically, it just means shortening the plastic to not dig in. If the sore spots are ON the ridge, usually this is an occlusion problem, (too much pressure). The general approach is to try one or two simple adjustments first and if that doesn't correct the problem, then the inside of the plastic (where the partial rests on the gums) should be completely relieved and a new impression made of the area for a total redo of the reline. Best is to use a tissue conditioning material for a couple of days to allow a full moulding of the shape of the gums, and use that as the template for the reline. Sometimes a soft lining material can be used depending on certain factors. Loose fitting implies the metal clasps may be slightly bent out of shape and need to be retightened. Additionally, if the upper is a complete denture and has not been relined or remade for several years, it is possible that the changes in the bone has changed the position of the upper which then changes the pressures on the lower which in turn can result in the discomfort. The critical aspect however is how much jawbone is left for support. Obviously this is the science, but the finding of someone qualified and concerned is unfortunately something I can't help you with, and Florida is not reciprocal with Michigan licensure. Sorry
