Dental Crowns After Root Canal Therapy

Boston Prosthodontics Dental Group

Root canal therapy is an advanced procedure that eliminates dental infection. When bacteria enter the pulp, root canal therapy is necessary to save the tooth from extraction. Oftentimes, a dental crown is necessary to add strength and reinforce a root canal-treated tooth.

Our team at Boston Prosthodontics in Boston, MA, performs root canal therapy routinely to restore patients’ oral health. In this article, we discuss dental crowns after root canal therapy so you can be well-informed about your treatment options.

What Does Root Canal Therapy Involve?

During root canal therapy, the infected nerves, blood vessels, and tissues are removed from inside the tooth. Next, the root canals and pulp chamber are filled with a restorative material called gutta percha. Finally, the tooth is sealed with a dental filling to reduce the risk of re-infection. Your Boston, MA, doctor may then recommend reinforcing the tooth with a dental crown.

When Is a Dental Crown Necessary?

A crown is recommended after root canal therapy if the tooth requires additional strength and reinforcement. For example, in order to perform the root canal procedure, the tooth structure must be altered. Placing a crown helps to protect the remaining healthy structure from damage and decay. It also restores proper function so patients can chew easily. In addition to addressing weakened teeth, placing dental crowns after root canal therapy can:

  • Reduce sensitivity to heat and cold
  • Conceal discoloration, which can occur after root canal therapy
  • Protect teeth that have received multiple restorative treatments

Types of Dental Crowns

The type of crown necessary will depend on your specific needs and goals. For example, front teeth are visible when you smile, so our doctors will likely choose an all-ceramic crown that will blend in with your natural teeth. The back teeth are responsible for chewing and must be able to withstand strong pressure and forces. As a result, metal crowns are often recommended in these areas. We offer porcelain-fused-to-metal crowns, which offer the strength of metal but the beauty of ceramic. Zirconia crowns are also available. Resilient and durable, zirconia crowns are one of the strongest restorations on the market.

Caring for Your Dental Crown

Once your dental crown is placed, it must be cared for like a natural tooth. While your new crown will be impervious to decay, the underlying tooth structure is still vulnerable. Here are some guidelines to keep your new crown in excellent working condition:

  • Brush twice a day with a nonabrasive toothpaste and a soft-bristled toothbrush.
  • Floss your crown at least once every day using traditional floss or interdental brushes.
  • Avoid sticky or hard foods, which can damage or dislodge your dental crown.
  • Visit your dentist routinely for exams and cleanings.
