Permanent crowns, oozed lumps of dried cement

Hi:The cement will easily come off without the need for removing the crowns.  Please go back to your dentist right away.Best,Dr. Maddahi

The cement is easily removed, so contact your dentist without delay, but DO NOT try to remove it yourself as you can cause yourself trauma, and the effect can be very unpredictable, possibly even damaging to your new crowns once the cement has gone hard. Good luck and kind regardsThomas Dey, BDS, MSc

Don't worry! The cement can be removed without any issues to your crowns. Sometimes the cement is clear and cannot be seen easily to remove it. Go back to your dentist and have it fully removed. 

You can relax, the dentist can remove the excess cement uneventfully.  In SOME cases you may need to get numb, but crown removal won't be needed
