Your tooth enamel is made up from a microscopic structure of crystallized minerals. While this makes your teeth very strong it does not make them invulnerable to damage. Something like a fall or a blow to the face can sometimes impact enough force to crack the enamel layer.
If you feel persistent pain in the cracked tooth, it probably means the damage extends down into the dentin layer of the tooth and might have even injured the root. This might require the dentist to perform a root canal and replace the enamel of the tooth with a crown.
Even if the crack in the tooth is shallow only limited to the enamel layer, you should still have your dentist look at it before bacteria can cause tooth decay. Your dentist might be able to repair it with a filling. Once the cracked tooth is repaired the might recommend a fluoride treatment. This will help strengthen the enamel and prevent future tooth decay.
