Thanks for using Health care Magic. Read your query. If you have mentioned that you want the same tooth back ,it all depends on many criteria including your gum conditions,time elapsed after the tooth fall and many other factors. If the tooth has fallen naturally and the socket is bleeding ,application of pressure with a clean gauge is advised .If pain ibuprofen will help(if not allergic to any medication. Do salt water gargling. Visit your dentist and evaluate the adjacent loose tooth.If cannot be saved ,have it extracted.Tooth replacement can be done once the socket is healed. Hope this was useful. Thanks and regards.
