Crown and screw fell off! What do I do?

The crown could be placed back on the implant  You need to see your dentist as soon as possible because tissue can grow and cover the implant In which case it will need to be surgically removed before the crown is replaced back ....

Hi:Go to your dentist right away, either the crown can be screwed back in with no trouble or the screw is broken.  Normally if an implant crown is loose you should get it tightened up right away.Best,Dr. Maddahi

Without xrays it is hard to be sure but it sounds like you had a screw retained crown and the screw loosened then broke while chewing gum. Or, it simply loosened and worked itself out. You should get to a dentist as soon as possible to evaluate it. Often, a new screw can be placed and your crown simply tightened back down to the implant. Just, don't wait too long to see your dentist.

You should go to your dentist immediately and see if the crown and screw are intact. If so, the crown can  be placed back into its proper position, the screw tightened and then torqued to 32 or 35  n cm.  If this crew has broken, it will need to be removed and replaced with a new screw.  The crown  can then be repositioned and then the new screw can be tighten and torqued to hold the crown in position.  

From your description, it sounds like your implant crown/abutment has come loose.  This can sometimes happen.  Simply save all of the parts and pieces that came out of your mouth (crown, abutment, screw, etc.) and call your dentist.  He/she can likely put the abutment back onto the dental implant (with a new screw of course!) and then seat the crown back onto the abutment.  You may need to get a tiny bit of anesthetic to have this done as the gum tissue over your implant will have likely grown a bit with the abutment/crown out of the mouth.  A laser can remove the extra gum tissue very quickly and no sutures should be required.  I hope this helps!  Good luck!

From what you're describing it sounds like this is not a big problem at all and the solution is really very simple. Chances are that you are actually holding two components, the abutment and crown.Your dentist simply needs to separate the abutment from the crown and reattach the two components to the implant.If the crown is "screw retained", then the solution is even simpler.Your dentist simply needs to screw back the piece that you are holding and place a sealing material over the opening.I hope you found this information to be helpful,Dr. Champagne
