Hello,
Had an upper molar pulled extracted earlier this week and recovery (with pain meds) has been nominal. On second day, noticed that, as I had been warned, an air passage had opened into my maxillary sinus. Perio got me back same day, found a pinhole and put in Gelfoam, secured with stitches. Trying to be careful with depressurization of my mouth, but once again, air movement into sinus (day after Gelfoam).
Follow up early next week and optimistic about healing but would like to know if Gelfoam is impermeable to air. Mayne I should jam a sugar free Gummy Bear in the socket

? Don't want no fistula! 😟
Too late Friday to see the dentist till Monday. Is it too soon to panic or should I simply try to avoid air movement (it's hard to do!) and be patient?
Thanks.
