For what length of time can i go without a crown on my broken tooth?

Hard to say: Don't know the condition of it, which one it is, current state of disrepair, and other pertinent info. No time frame can be given; the longer you wait, the better the chance for complications resulting in the loss of the tooth.

Don't know: If you want to keep this tooth you need to, get it treated. No treatment and the disease process will continue until you loose the tooth. Talk to your dentist about the financial part of getting the crown.

Until .........?: There is no way to answer that for you, especially without us actually being able to see the tooth & the x-ray. It depends upon whether or not you have decay, how much is gone, how much sound tooth is left, the strength of the opposing tooth, your eating habits and the luck of the draw. Your own dentist can help answer how best to handle both interim and final solutions along with the finances.

It's your call: Unfortunately you have to decide how much risk you are willing to take. If the tooth fractures down the root, the tooth will need to be removed, and to replace that tooth will cost significantly more than having the crown. Good luck.

Dentist to evaluate: The decision is yours. It is all dependent on where the tooth is located. The teeth in the back, should be addressed ASAP to avoid vertical fracture and possible tooth loss, which can add added aggrevation and monetary outlay. It is also dependent upon how much tooth structure in left in theoriginal preparation or area of decay. Have your dentist evaluate to be sure.
