Tooth damage comes in numerous forms and degrees of intensity, and in some cases, it may prevent certain procedures from being performed. If the crown is severely decayed or if a large portion of it has broken off, then a replacement crown will require other procedures to be done in advance before it will be viable. The reason for this is there is often nothing for the new crown to hold to, and thus it would not be stable.
In order to overcome this obstacle, we perform a core buildup procedure. This constructs a core on the original tooth that will allow a crown to be fitted securely. It also helps preserve as much of the original tooth structure as possible, particularly the roots. This has the benefit of providing extra strength to the tooth and reducing sensitivity.
On a tooth where a significant portion of the crown has decayed away or broken off, a new crown is needed. However, the new crown needs something to grip on to, so your dentist will probably perform a core buildup procedure. Here is how the process takes place:
- Decayed tooth structure is cleared away: Before anything else happens, the tooth must be free of decay. This allows the resin used to bond to healthy tooth structure rather than half-dead stuff that will only rot away.
- Apply solution: A mild solution is applied to the surface of the tooth where the resin will be placed.
- Apply and cure resin: A composite resin is placed on the tooth structure where it is then allowed to harden. Some resins cure on their own while others are light-cured—in other words, a high intensity light is used to harden them.
- Sculpt: Once the resin hardens, it is then sculpted into shape. It needs to be formed in such a way that it will fill the crown that will be placed over it. At the same time, it shouldn’t be so big that it keeps the crown from making contact with the original tooth structure.
Once a core has been built and sculpted into shape, a crown can be placed on the tooth.
Core buildup is often necessary to keep a new crown stable, but it does have a few requirements to be most effective. Particularly, the root of the tooth must be intact. If it is not, then other procedures—such as a dental implant—may be necessary.
In some especially severe cases, a root canal may also be necessary prior to the procedure. This is because a pin or post may need to be drilled into the root to give the core more stability. However, given the advances in the materials used for core buildup, a pin is often unnecessary since the substance will bond directly to the tooth structure.
Finally, it is absolutely crucial that this procedure be done by a highly competent dentist. Otherwise, complications can arise, especially in cases where a post or pin is necessary.
