Root Canals Q&A

Why choose a root canal?

A root canal serves to eliminate the nerve of the affected tooth, ending painful sensations and clearing away infection of the pulp tissue.  Once the procedure is complete, your root canal treated tooth will be restored with a dental crown that functions just like your natural teeth.

How do I know if I need a root canal?

The primary indicator for root canal is dental pain. Your teeth are made of living tissues, and damage or infection prompts the nerve within a tooth to transmit pain signals to your brain.

If you notice increasing tooth pain, it's important to schedule a dental examination. If the pulp is infected, delaying treatment could result in a painful abscess.

Additional symptoms include swollen gum tissue, tooth discoloration, and increased sensitivity to heat or cold. These signs should prompt a call to Dr. Pan.

How is a root canal performed?

During your first appointment, Dr. Pan administers a local anesthetic to help you remain comfortable. A protective device known as a dental dam helps isolate the affected tooth during the procedure.

Dr. Pan creates a small access into the coronal portion of the tooth. That allows him to insert extremely small instruments called files into your pulp chamber for disinfection. Those instruments enable removal of all affected dental pulp tissue and help prepare the interior of your tooth for the next step.

Dr. Pan then fills the inside of your root canal with a biocompatible material called gutta percha.  Dental cement stabilizes this material in place, sealing your canal spaces. A temporary filling closes the small opening in your crown. The root canal treatment is now complete, and the tooth is ready to be restored with a crown.

Does a root canal require special care?

A crown is required to support the overall tooth structure after root canal treatment is performed.  Avoid biting down or placing any excessive pressure on the tooth to prevent fracture if a crown is not already cemented.

Once a crown is cemented into place, it is structurally more stable. From that point forward, simply use the same dental hygiene practices you use to remove plaque from your natural teeth.
