Im having teeth sensitivity that comes and goes. Pain goes into my gums and its mainly on the left side.  This has been ongoing for a few days and occurs during the night also. I thought maybe sinus problems but Im not having a headache or pressure other than in my teeth.
Hello, Pain in gums with teeth sensitivity can occur due to causes like gum infection like gingivitis or periodontitis while it can also be due to a sinus infection or sinusitis if you have some associated symptoms like nasal congestion, nasal discharge, facial pressure, headache etcetera. So my suggestion is to consult an oral physician and get evaluated, and a panoramic x-ray should also be done, so that the teeth, as well as the sinuses, can be radiographically examined. In case if there is gum infection, then a thorough cleaning or scaling will be done followed by a course of antibiotics like Metronidazole and gum paint massage. Also, take a vitamin C pellet or candy daily as it helps in strengthening gums. If it is due to a sinus infection, then antibiotics like Augmenting and decongestant nasal sprays like xylometazoline, saline nasal irrigation, and steam inhalation can be advised. Hope I have answered your query. Let me know if I can assist you further.
