<s>[INST] My left upper gum was hurt since Saturday.  I used an orajel and motrin 800 to calm the pain, but somehow it doesnt help much.  I had a missed period almost two months, I tested but was negative.  I did some research, not sure of my hormone change and cause the gum or what?  Can I be pregnant and caused the gum pain or should I see a dentist regarding this matter.  Thank you! [/INST] Thanks for your query, I have gone through your query. The pain in the gum could be because of any trauma to the gums while brushing or eating leading to ulcer formation. It can be because of the gum infection secondary to deposits. Ya hormonal changes do cause some changes in the gums but not pain. Consult an oral physician to rule out these causes. And get your teeth cleaned once and take a course of antibiotics after consulting a dental surgeon. Do saline gargling. I hope my answer will help you, take care. </s>
