Sue i have had a number of crowns and they do take forever! Dental work is worrisome with the inhaling issue but we have to do it. My dentist has a vacuum thing they put near by but i don't think it helps that much. Interesting that you had the same experience after lying inverted for a long period of time. I also would have to sit up to clear. I felt like that part of going to the dentist was actually good therapy. They sell inversion chairs and i have been tempted to get one but doubt i would want to invert for such a long period of time to get the results or if my pulmo would recommend it. I think i will ask him.

Sue & Irene When I first started productive coughing from bronchiectasis a few years ago I found laying back in a dental chair always induced a cough. Postural drainage is now my most reliable method to bring up sputum out of all my various airway clearance techniques. For me late morning is usually the best time of day. So I always get a dental appointment late in the afternoon to help reduce the coughing. Also when I need to produce sputum for a culture I will figure out a way to time it late morning and find a place where I can lay on my back in order to get a good amount of sputum for the test. Timing is everything!!! Bill
