I had a root canal 3yrs ago on ur biscupid tooth. i couldnt afford to get it crowned at the time. what can happen from not doing that. i plan to soon?

RT Therapy: Teeth that have undergone root canal therapy are more brittle than vital teeth and can fracture vertically, especially bicuspid teeth. Recurrent decay on these restored teeth can go unnoticed since there would be no sensitivity associated with the decay. The sooner you restore the tooth properly the better the chances that it will remain intact.

Root canal treatment: To be successful, with the best long-term prognosis, a root canal treated tooth has to be carefully sealed at both ends. Standard of care, to support the remaining tooth structure and seal the treated tooth, a crown is necessary. You are playing Russian Roulette. Please see your Dentist ASAP to determine your status and appropriate care going forward.
