Only my second time having to go on Pred for a flare, but YES!!!! on the sensitive teeth. I never read about that as one of the (many many many) side effects of Pred, but about 6 weeks into my treatment I pretty suddenly noticed sensitivity in all of my teeth, mostly to cold. So bizarre. Also headaches and general 'weird feeling' each time I step down.
As an aside, regarding side effects of Pred since everyone is different: I am very petite to begin with, but have been on Pred (starting at 40 mgs) since early March and have not gained any weight. I have a bit of chipmunk cheek syndrome and a bit of a pooched out belly just under the belly button, but otherwise have been super lucky. Just a ray of light out there for people who are distressed about starting Pred regimine....it truly is different for everyone.
