Consult with the dentist who is placing the bridgework to be sure there is a good margin in the affected areas. The margin is where the crown on tooth and the natural tooth structure meet. The margin should be closed. If the roots of the affected teeth are not covered either by gum tissue or the bridgework, check with the dentist to see if it is possible to re-prepare these teeth, and subsequently remake the necessary sections of bridgework, to carry the margin below the gumline. If none of these suggestions are feasible or prove ineffective, you should consider having root canals.
Teeth become brittle after root canals are completed.
This is one reason we recommend placing crowns after root canal treatment. Since your teeth will already be covered, that consideration is not a concern for you. Just be aware that while root canals have an extremely high success rate, some do fail. If the teeth develop prolonged sensitivity to temperature, a root canal or extraction may be required. You should not rely on this information as a substitute for personal medical attention, diagnosis or hands-on treatment.
