Hi! Welcome to Healthcaremagic. I read your query. You did not mention if the cysts are related to that particular tooth only or are they occuring in different parts of mouth. If its occuring in that tooth, i suggest you to visit an oral surgeon and get an x-ray done. If the tooth and bone condition allows, it can be treated by apoecectomy of that tooth. Its a minor surgical procedure unfer local anesthesia. A new crown of good quality can be placed after that procedure after some crown cutting. Or there are other ways like post and core etc. for crown restoration. All this require oral and radiographic check up by a dentist. Hope the answer helps you. Thank you.
