I would definitely get the tooth checked out. The nerve may be dying and although it won't fall out it will change the color of the tooth and look bad. This is well worth a trip to the dentist's office and with this economy dentists are allowing patients to make payments.
Hi,
First thing. DON'T WIGGLE IT. Teeth can tighten back up if left alone and not too badly damaged.
Just baby it and see if the painful sensation to heat and cold goes away.
If not, you may need a root canal, but many injured front teeth need nothing but to be left alone.
Be very gentle with it. It can take several months for it to completely heal.
GOOD LUCK.
My best to you,
Gellia
