Why it is important to place crown in Root Canal treated tooth

Root canal treatment is an extremely common procedure in dentistry. It is performed when the infection has reached up to the pulp which is present in the centre of the tooth. Another most common reason for performing root canal treatment is when the tooth has undergone trauma exposing the underlying pulp. The pulp involves a plexus of blood vessels and nerves which maintain a hydrated environment inside the tooth and provides it nutrition for its normal functioning.  Exposure of the pulp due to dental caries or trauma can cause pulp to get infected due to ingress of oral microorganisms into it. These microorganisms slowly breakdown the internal environment including the blood vessels and nerves and lead to production of pus. This pus formation further extends beyond the root of the tooth and destroys the bone below the tooth. It is accompanied by pain or swelling or both. Root canal treatment is performed in teeth which are infected or traumatized and have intact external anatomy. The procedure involves cleaning the root canals to remove the infection, shaping the canals and filling them with biocompatible material. The whole purpose of root canal treatment is to remove the present infection and prevent future infection. Once the root canal treatment is completed, it is important to place a crown over it. There are multiple reasons to why a crown should be placed invariably on a root canal treated tooth. The most important reason is after root canal treatment, the natural environment of the tooth is disrupted making it dry and week. It becomes brittle and can break easily on putting even a small amount of force. The tooth can break in such a way that re root canal treatment has to be done and in some cases the tooth has to be extracted. Another most common reason to place a crown after root canal treatment is the chance of re-infection.  Artificial fillings are used the fill the tooth after root canal treatment in the coronal part of the tooth. As a matter of fact, even the latest and best artificial fillings do not match up to the nature of a tooth. When the temperature changes occur inside the mouth as a result of eating and drinking, the tooth and the filling contract and expand at a different rate. This results in formation of minute gaps around the fillings which allow the saliva and microorganisms to reenter the root canal space and cause re-infection. This phenomenon is called microleakage. Another important reason for placing crown after root canal treatment is that the filling placed in the coronal portion of the tooth can fracture and dislodge due to constant heavy biting forces. This in turn can result in re-infection of the tooth causing pain and swelling. As a result to increase the success of the root canal treatment and maintain the integrity and strength of the tooth, crown placement is highly indicated. There are different types of crowns including complete metal, Porcelain Fused to Metal, Ceramic and Zirconia crowns. Metal crowns are high in strength but lack aesthetics and give a metal look to the tooth due to which they are discouraged by the patients to be put in their mouth. Porcelain fused to metal (PFM) crowns have a base layer of metal with a tooth colored layer on top. They are aesthetic as they have an upper tooth colored layer but have a disadvantage that this top layer can get fractured by lateral forces exposing the underlying metal layer because of it has to be replaced. Also the color matching to natural tooth is of comparatively inferior quality. Ceramic and Zirconia crowns a completely tooth colored overcoming the disadvantage of PFM Crowns. They are highly aesthetic with superior color matching to natural teeth. Zirconia crowns also have high strength along with superior aesthetics making them dentist’s choice for the ideal crown to be placed inside the mouth.
