What is a root canal?
A root canal is a dental procedure to repair damaged or infected teeth. It involves the removal of the dental pulp within the tooth, followed by the cleansing and disinfection of the root canal. Then, clean rubber-like dental material is inserted into the canal and sealed. Common causes for damaged pulp include cracked teeth, deep cavities, or repeated treatment to a specific tooth.
Why is a lab based crown added?
A crown may be added a few weeks after the treatment as it is made in the lab. This is because the treated tooth has lost its pulp, it cannot function as a living thing, and it will eventually weaken. The crown strengthens the tooth and protects it form bacteria.
