MY CROWN HAS COME OFF. WHAT CAN I DO? 

If your crown has come off you can use a little bit of denture adhesive or chap stick or petroleum jelly or even toothpaste to temporarily hold your crown in place. Place a little bit of denture adhesive, chap stick, petroleum jelly or toothpaste in the crown, and making sure that it is positioned correctly, press the crown back on. This will help to temporarily hold your crown until you are able to see your doctor.
