[/INST] Hi and welcome to Chat Doctor, As you said you have undergone a Flap surgery for your gums to save your tooth and it's been 5 years now. So the area is giving you problem after a long time. This needs an x-ray examination of the affected area which will show if there is some infection or bone loss. Pain in the molar on biting indicates decay or some kind of pupal infection, or root caries.I suggest you to consult a dentist and get an OPG radiograph done which will show the success of flap surgery done, condition of gums and underlying bone. Till then, you can have diclofenac with serratiopeptidase tablet which relieves pa intake care. </s>
