I have a 10 month old crown on my front tooth & its suddenly hurting me very badly. i can barely eat due to pain when biting. what can cause this pain?

Have it examined: Pain can be coming from different issues.. sinusitis, an infection, a fracture, and even a non-vital nerve. Best bet is to not guess and have your dentist take a look.

Crown: Tooth under the crown may be infected, tooth may be fractured, or you may have a hyper function problem. Please see your Dentist. Services of a root canal specialist, an Endodontist, may be called for.

Dental exam needed: See a dentist ASAP to get this evaluated and treated. You are having symptoms of an infection or Abscessed tooth.

Contact DDS: Go to the dentist for a complete clinical and radiographic examination. Variables include, loose crown and need for recementation, need for root canal therapy, occlusal interference or periodontal issues. The dentist will also rule out possible trauma.

Infection or a crack: Like any other tooth, a crowned tooth sometimes develops an infection or crack/ fracture in the root and needs to be treated by the dentist or endodontist.
