What additional dental work is needed for a tooth that has had a root canal treatment?
After your tooth's root canal treatment has been completed Dr. Hernandez will need to discuss with you what additional dental work will be required so to make the tooth fully functional again.
Many times a tooth that has required root canal treatment is one that has a big filling or else has large portions missing due to decay or breakage. These teeth, in this state, are not as sturdy as they once were and for this reason it is commonplace that a dentist will recommend that a tooth that has had a root canal treatment should be restored with either a dental crown or else a dental crown in combination with a dental post. Of course Dr. Hernandez will need to determine what treatment is appropriate in your situation.
The dental restoration that is chosen for rebuilding a tooth that has had root canal treatment provides another function also. It provides a seal protecting the interior of the tooth. This barrier helps to prevent seepage of bacteria and contaminates from the oral cavity into the interior aspects of the tooth. Dr. Hernandez will need to advise you as to what they think is best for your situation but, in general, the sooner arrangements can be made to have the permanent dental restoration placed (thus creating the best possible seal) the better.
Placing a post in a tooth that has had a root canal treatment
A "post" is a rod that a dentist has positioned and then cemented in the canal space in a tooth's root. Typically, but not always, dental posts are made out of metal.
Posts are usually only placed in those teeth which have extensive portions of their natural tooth structure missing. Dentists know, in general, that the greater the amount of a tooth that can extend up into the center of the dental crown, the more stable the crown will be. In those cases where a great deal of tooth structure is missing a dentist will "build up" the height of the tooth using dental filling material. A dental post provides a way for the dentist to securely anchor this filling material core to the tooth.
How does a dentist place a post in a tooth?
When placing a post in the tooth, your dentist will first use a drill and remove some of the gutta percha filling material that was placed during the root canal treatment treatment. They will then cement the post and subsequently place a core of filling material around the post's upper portion, so to increase the overall amount of structure that will extend up into the crown.
Placing a dental crown on a tooth that has had a Root Canal Treatment
Crowns are dental restorations that cup over the portion of a tooth that lies above the gum line. People sometimes refer to dental crowns as "caps." Dental crowns can either be gold or else have a porcelain surface so they look white like a tooth's neighboring teeth.
A dentist will use a crown as a means of improving the appearance of a tooth, restoring a broken tooth to its original shape, and/or strengthening a tooth. Additionally, and very importantly, crowns create an excellent seal over a tooth. By this we mean that a crown cemented in place provides a barrier that is helpful in preventing bacteria and contaminates from seeping back into those inner aspects of a tooth where the root canal treatment has been performed. After a tooth has had its root canal completed, any or all of these qualities which a crown can provide may be needed.
What steps are needed to make a dental crown?
Before a crown can be placed the tooth must first be trimmed so it is tapered in shape. This tapered aspect of the tooth will extend up into the dental crown center and is a very important factor in the crowns stability. After the needed shape has been achieved your dentist will take an impression of the tooth, which in turn is sent to a dental laboratory which will create the crown. Once the dental lab has completed your crown, Dr. Hernandez will cement it in place.
