<s>[INST] I am experiencing a small place (fluid filled) near my lower right molar in the fatty pad.  It comes and goes at various times and I can pop it open.  There is no pain and is only a red color. There is no pus noted.  What is it and how can I get rid of it.  Thanks so much!! [/INST] Hello and welcome.Thanks for sharing your concern.Please note that the fluid filled  tissue could be an abscess or pericoronal abscess around the third molars.Therefore in such case please see your dentist and start antibiotics and analgesics.based upon clinical evaluation operculectomy could be the treatment option.for now please take analgesics.Thanks.Take care. </s>
