I was diagnosticated with sleep apnea and the doctor prescribed for me a continuous positive airway pressure (CPAP) machine (through my nose). After four days I noticed that the pressured air pass to my mouth through the little hole that communicate my nose and my mouth. I got a molar extraction on February, and during the extraction one root was broken. It was difficult to extract that root; then, I got a dry socket, which was very painful. I never receive a treatment to close the communication between the mouth and the sinus, because the doctor said the hole was small and it will be closed alone. Then I got an infection that was treated with antibiotics several times until the Otorhinolaringoly (ENT) cleaned the sinus in a surgery.
Then Doctor changes the mask for a bigger one that covers the mouth, but I do not feel comfortable with this mask and I am concern about the hole. Then the Doctor told me that I have to use another mouth device which, initially the Doctor does not recommended it to me because it is prescribed for mild and moderated sleep apnea. Then he told me that I have to return the machine. I would like to continue trying with the big mask and I would like to know your opinion. Is there any risk if I continue with the CPAP machine?
