More necessary Dental work needed to restore the normal tooth form and function after a root canal therapy. The root canal treated tooth usually requires restorative dental work to be done to make the tooth tougher as before the treatment. This restoration of the root canal treated tooth is very important in the regard that it helps to seal the interior of the treated tooth from contamination by bacteria or other debris present in the saliva in oral cavity.
The type of restoration recommended to you by the dental professional will depend on your dental condition which could comprise of any of the following:
A dental post is a rod like structure which is placed in the endodontically treated teeth that have a large part of the structure of the tooth missing. In order to increase the strength of the remaining tooth structure the dentist has to increase the amount of tooth structure which would extend into the center of the crown to be placed on a root canal treated tooth. This increase in structure can be achieved with the help of a dental post which will serve as a pillar for the filling material which would increase the height of the remaining tooth structure.
A dental post is most of the time but not always made of metal. It is placed in the canal space by drilling out some of the gutta percha filling from the root canal. The post is cemented after checking the fit of the post into the canal space being used to place the post and then a core of filling material is used to fill around the top part of the crown. The entire assembly of the post is called as the post and core where the post is the portion placed inside the root canal and the core is the portion build up around the upper part of the post extending in the crown to be placed over the tooth to replace the missing tooth part.
Dental Crown - Dental crowns also called as dental caps, tooth crowns or tooth caps are a type of dental restoration that covers or encloses the tooth on which they are cemented. As compared to the other restorations which are used to cover or fill the tooth partially a crown completely encloses the portion of the tooth above the gum line and entirely becomes the outer surface of the tooth. Crowns are made up of metal or porcelain (ceramic) and even a combination of both. Metal crowns are usually used to replace the back teeth due to their strength and because the back teeth are less visible so aesthetics or looks of the patient are not compromised. Ceramic is the best choice in front teeth as being tooth colored material it gives the best looks and even the strength is appropriate for the front teeth region. A crown is used to restore the damaged tooth, provide strength to the remaining tooth structure and also improve the appearance of the patient. They act as very good barriers and don’t allow the bacteria to penetrate and re-contaminate the canal again.
The Root Canal Treated tooth is prepared for crown by cutting the treated tooth into a tapered form extending till the center of the crown. This form provides maximum stability. An impression is made and sent to lab to prepare a crown for the tooth.
The crown from the lab is checked for fit in the mouth and then cemented into place.
A dentist may give you a temporary crown till the permanent one is made and all the adjustments of occlusion etc. can be done on the temporary crown so that the finished permanent crown fits with complete accuracy needing minimal adjustments.
