How do you get fingernail out from behind your front tooth?

To remove a fingernail stuck behind your front tooth, gently try to dislodge it using a soft toothbrush or dental floss, being careful not to cause injury to your gums or tooth. If that doesn't work, rinse your mouth with warm salt water to help ease any discomfort. If the fingernail remains stuck, it's best to consult a dentist for professional assistance to avoid damaging your teeth or gums.
