I generally have always had good teeth, no problems a cavity here or there, but my teeth have been awful lately and I brush constantly because of coughing 24/7. I have pseudomonas and am currently taking Cipro 2 weeks out of each month for 12 months. My boyfriend thought it might be my neb meds causing me to have issues but I have had to get two root canals and now I have lots of cavities. Has anyone else had issues with psuedo and their teeth?
