One of St. Lawrence Dentistry’s goals is to try to help you avoid procedures like root canals and dental crowns. However, in some cases, they are needed.
A root canal through a dental crown is a subset of root canal treatment, which requires more time, skill, and specialized equipment to complete compared to a regular root canal treatment. Dr. Hawryluk Jr. has performed thousands of successful root canal treatments under these circumstances.
Dental crowns are the most durable and anatomically correct type of dental restoration. They are the restoration of choice for a tooth that does not enough tooth structure left to put a proper simple filling in place. The procedure of doing a dental crown involves shaving a tooth down about 1-2mm in all directions. This process is called the ‘crown preparation’ and to makes space for the porcelain crown. The act of reducing the tooth down can create trauma to the tooth nerve (dental pulp) — most of the time, the nerve recovers after one to two weeks. However, in some circumstances, the tooth nerve may not recover, and that can necessitate the need for root canal treatment.

Root canal treatment involves cleaning out the dental pulp of the tooth or its remnants, sterilizing the space created by the cleanout, and filling it with Gutta Percha Rubber.

It can be frustrating for someone who has already gone through the time and expense of having a dental crown placed to find out they need also need root canal treatment. Fortunately, Dr. Hawryluk can often preserve your dental crown and do any required root canal treatment while keeping your dental crown in place.
The first step involves making an opening through your crown. Dr. Hawryluk will gently remove some of the porcelain (and possible metal) to access the tooth underneath. The dentist accomplishes this step slowly to minimize any stress on the surrounding porcelain to reduce any craze lines developing in it. Next, the canals will be located and cleaned out. Using a dental microscope is critical when doing root canals through dental crowns as visibility is often reduced compared to working through teeth without crowns. After cleaning the root canal system, the doctor will sterilize and seal the canals completely. Finally, the opening through the crown is closed with composite resin.
