I have a terrible pain in my front tooth, the pain has gotten worse since yesterday, constant pain, doesn't look infected and gums are not swollen?

Probably root canal: All pulp problems are not infected! you can have severe inflamation of the pulp and severe pain without any signs on x-ray or swelling clinically! get to an endodontist asap.

See a dentist ASAP: It is hard to answer if your tooth is infected, cracked or just bruised without a history and x-rays. Early intervention is recommended. See a dentist.

Front tooth pain: If pain came on spontaneously without any trauma, a root canal is likely needed. See your dentist sooner than later.

Terrible Pain: This tooth needs immediate evaluation. Please call a local dentist for an appointment. A radiograph can reveal so many things that we cannot diagnose over the internet. It could be that the nerve died and you need root canal therapy.
