Thanks everybody for your reviews. I went to the dentist here in dgte (I won't mention the name) the dentist informed me there is nothing wrong with your back molar tooth. The dentist told me you must have a sinus problem, so off we go to Silliman med to have the doc's check with x-rays if there is any blockage. The Dr there stated there is no blockage normal paranasal sinus. Its your tooth.
I have had enough of the failed procedures here after living for over 10 years in Dgte I went back to my Dental surgeon in Cebu and had two root canals carry out on the tooth. Expensive but the job is done.
