Restorative dentistry has a large vocabulary. It’s easy to get confused about the differences between posts, cores, root canals, crowns, and so on.
How do posts and cores relate to crowns?
Get A Grip!
Crowns replace a tooth’s outer layer if it’s been damaged by decay or fracture. Caps take things a step further when a filling is insufficient.
But what happens when even a crown isn’t quite enough?
Dental crowns depend on a tooth having a solid core for support. Without a core, there’s not much for the cap to hold onto.
An artificial core is often made of a similar material as white dental fillings. Your dentist molds it into the tooth to create a new foundation for supporting the crown. This core is typically secured with small pins to help it hold onto the existing tooth.
Posts to Stabilize the Core
Your dentist will call on the help of a dental post if more than half of the natural crown (upper portion) of your tooth is missing, and the core needs more support to stay on the tooth.
At this point, your tooth should already have had a root canal. Posts cannot be placed in teeth without endodontic treatment. The dentist must drill down into the nerve chamber of the tooth to create a hole for placing the post. You don’t want this done on a live nerve!
After the root canal is completed, a dentist places a sturdy metal plug in the excavated area. Then, the core material is packed around it and a crown seals off the whole thing.
Talk with your dentist to learn which restorative techniques are right for saving your tooth.
