Hello Antonina: Welcome to NeuroTalk! I'm sorry I cannot comment with regard to treatments for your loose tooth. However, do check out the stickies at the top of the Dentistry & Dental Issues forum listing. There are links to quite a few valuable dentistry-related websites there. Hopefully you've already found the list of Similar Threads at the bottom of this page. And also use the Advanced Search function to find previous posts related to your concern:
