<s>[INST] I have a problem with my tooth/teeth/gums I think.  I went to different dentists a few times and they couldnt see anything wrong on the xray.  When I floss/use teepee brushes between certain teeth its very painful and it bleeds.  My right side of my face is slightly swollen and the area just under my jawbone is slightly swollen and tender. Ive had this problem for over a year now and lately i have just noticed it more. I think it might be an infection because your glands can get swollen with that cant they?  Ive been feeling sick on occasions aswell and yesterday when I woke up, I felt awful and my temperature went from 37 celsius up to 38.60 celsius.  I felt better next day, but still feel a bit sick.  Could this be a tooth infection? [/INST] Hello. As you said several times after x-rays dentist denied for any tooth infection. So you should believe that it can't be tooth infection. You may need scaling if gingival bleeding is due to calculus. If not have check up for blood reports once by consulting physician. For swelling on side of your face you can go for orthopentomogram, X-ray of whole face.to get more idea on condition. You can consult back for further queries. With you good health. </s>
