I've been using the Narval for 2 years - love it. Changed my life. I use it 100% of time, for 100% of night. However the lower jaw part keeps slipping off. I think I've worn it out - it does not grip my teeth as tightly as it use to. I've been using PolyGrip denture cream to hold it in place at night. Not great, but does the job. Is there a way to permanently improve the tightness of fit of the lower jaw component?
I currently have the rib settings at 24mm - pretty tight. I have a relatively smaller mouth/jaw (actually use women's model, not male version). Could it be that I have the connectors too tight and I should back off to a wider setting? In general, the tighter the fit the better I sleep (the more oxygen) and don't care if jaw is a little tight the next day. I may have tightened it too far?
