I've had my sleep apnea device for at least a year in that year I've had one side of it break a loose completely because my dentist didn't know that it was supposed to be adjusted with my jaw forward. My dentist finally figured out how to adjust it where the jar feels like it's forward. That was the best week sleep I've had in a long time no phlegm no waking up every hour it was a really great week but now it won't stay adjusted so I was wondering if I should ask her to get me a new mouthpiece or just keep going back to get it adjusted like it supposed to be?
