I have a theoglossal duct cyst and it seem to be getting bigger with this bacterial infection ive been having....the infection came from a under the crown root canal decay that infected my face numb till this day and swollen, i recently had a tooth extraction done now its both side of my face. but my question is can a bacterial infection cause the cyst to grow?
Thanks for your query, I have gone through your query. The infection from the tooth cannot cause infection of the hypoglossal cyst. Thyroglossal cyst can get infected secondarily. Consult an oral and maxillofacial surgeon and get the cyst enucleated. Before that you can take a course of antibiotics and analgesics like amoxicillin 500 mg and metronidazole 400 mg TID for 5 days (if you are not allergic). I hope my answer will help you, take care.
