I have a pain sensitivity in my upper left molar area. Dentist examined and found nothing.  It feels like a gum inflamation and is sensitive to cold liquid..I am suspicious that it may be sinus related, as it hurts when I blow my nose to clear nasal congestion. It isnt constant, but feel it most of the time.  Also hurts when I brush the gumline (pocket) on back side of the last molar.  It has been approx 2-3 weeks since I saw dentist. Thanks.
Hello, Thanks for writing to us. The pain sensitivity in upper left molar can be due to bone loss or periodontitis of the inflamed tooth. Get a deep scaling done. X-ray of the tooth will help to find out any infection underlying. Meanwhile, maintain oral hygiene well. Brush and floss your teeth daily. Take care.
