I have had dental pain, my tooth has cracked. do i have to get it pulled?

May be not: It is depending on where, how severe the crack is ? What causes it to crack ? You might not have to get it pulled, but you definitely must see a dentist before the problem escalates. Small repair and restoration....Small fee. Large and difficult situation.....Large fee.

Possibly: If you have pain when you bite, it is possible that you have a cracked tooth. Sometimes you may be able to save the tooth with a root canal and a crown if the crack is not too big or has not split the tooth in half. You need to visit your dentist as soon as possible to have it looked at.

Not necessarily: Depending on what part and how much of your tooth has been lost, you may or may not need it removed. If the tooth is essentially intact with only a section broken off, then you might only need a crown. If the tooth is painful to bite on, you might need a root canal then a crown. If the tooth is deeply fractured, then it might be removed. See your dentist asap to be sure.

Maybe not: Depending on the severity of the fracture, the tooth may be able to be saved. A cracked tooth almost always requires a root canal because there is now an opening into the dental pulp. After the root canal, you will need a full coverage crown to protect the tooth because fracture and root canal causes a great deal of loss of tooth structure. See your dentist for an evaluation of the tooth.

Dentist ASAP: See a dentist asap. With a cracked tooth, taking your time is not your best option. At the beginning a crack may be able to be caught and filled or crowned. Waiting can allow the crack to spread and become more serious and you may lose the tooth.

It depends...: This depends on how far the crack goes. It may also depend on the context: where is the tooth in your bite and what other factors affect the equation. Your best bet is to see your dentist yesterday ;).

Sometimes: Sometimes if the crack is below the gumline, the tooth cannot be saved. Often it can be saved. The best prognosis is with seeing your dentist ASAP.
