So I cracked/fractured my upper right central incisor. The anterior portion is about half cracked and the posterior portion feels as if about 3/4 was removed (sorry if those aren't the correct directional terms, but I can't really think of another term) due to the angle of the fracture. I still have the portion of the tooth that was chipped off. This happened yesterday afternoon and I'm going to call my dentist tomorrow morning, but is there anything I should be doing in the meantime? Is there anything I can or can't eat and should I be brushing my teeth? Is it an emergency (as in should I contact my dentist now)? What should I be prepared for in terms of treatment options and costs?
