Hi Dr, I removed my upper right wisdom tooth 6days ago. While the tooth was healing, i lost a blood clot about 4 days ago, but the tooth is healing fine with no too much pain. My problem is pressure in my right maxillary sinus close to the roof of my mouth. The whole of my right face feels immense pressure especially just on the right side of nose and the roof of my mount. the dentist told me that it may be an inflammation and instructed me to use sudafed, but is not working. What can i do please?
