<s>[INST] I had a dental extraction that went bad and a burr, and tooth root were lost in my maxillary sinuses. The burr fell out on its own about two weeks later, but the root remains, and I am in daily pain 8 months later. I have been recommended the Caldwell Luc procedure to remove it, but I am not comfortable with the associated risks, and would like to know what alternatives, if any, I have. Thank you so much in advance. -Naomi [/INST] Thanks for using Health Care. Read your query. Root present in the maxillary sinus has to be taken out completely. If left behind it may lead to further infections and complications. If I had a patient with the similar complaint, I would immediately suggest undergoing the surgical procedure for the removal of root and to be followed up regularly. Visit a good Oral and maxillofacial surgeon and have it done as all procedures cannot go wrong. Relax. Hope this was useful. Thanks and regards. </s>
