Hi, If the tooth/teeth have come out completely then you need to rinse out any dirt in water (do not scrub) and keep it in milk.Carry it to your dentist if only a few hours have elapsed.In many cases it may be possible to reimplant the tooth. If the teeth have partially broken then you will need to see your dentist as these can be repaired with tooth colored fillings or crowns. In either case and especially in case of swelling,rinse out the wound gently and give cold ice packs.

Hello ! If it was completely out then you can place it in cold milk and take to dentist so that it can be reimplanted with in few hours ,  but I think you already crossed time . And if it was broken little then there are few methods to restore like either composite buildup or crown depending on the severity .
