When you have a root canal done thru a porcelain cap will that cap then have to be replaced?

Question

I had a root canal done by an endodontist and he drilled thru the cap. When I went back to my dentist he said the cap will now crack and needs to be replaced...an expensive proposition. Is it necessary?

Answer 1

It really depends on the type of material the crown is made from. All porcelain, bio 2000 and some of the others have a tendency to crack more easily, or he may see a crack started that was caused from the drilling to access to the pulp chamber. Porcelain is glass and is very susceptible to cracking from the drilling itself.

In most crowns it's usually not necessary; they can be sealed without removal using a composite material. All of this depends on how large the access opening is, if the porcelain was fractured and what caused the need for the root canal therapy in the first place? I doubt this root canal therapy was because of decay, if that were the case they would have removed the crown for easier access to the pulp chambers and would have known the crown would need replacing. It possibly died after having the crown placed some time ago for some unknown reason. I am guessing it’s an all porcelain crown that has a fracture now from the procedure. A crack or fracture will allow leaking to take place over the years to come or allow it to eventually just break apart.

If it was decay under the crown it needs to be removed. Then the margins will more than likely be compromised with the removal and excavation of decay and new build up process. The decay can't just be left under a crown to continue to destroy the tooth structure under it. Crowns have to fit perfectly in order to protect the tooth from any leakage at the margins that could promote decay under the crown, especially in root canalled teeth. I've seen too many root canalled crowns come off with a non restorable decay ridden tooth where the natural tooth used to be. You just can't see or feel the decay in a root canalled tooth. This decay can't be picked up on an x ray either since you can't see through a crown to determine if there is decay or not. The decay is usually found during your cleanings by the hygienist.

So I would advise you to take your dentist advice and if he says it needs to be replaced, then ask why and let him tell you, but replace it to protect your natural tooth structure if he recommends it. I don't know why you had the root canal or how old the crown is so I'm giving you ideas as to why he's suggesting a new crown. It’s a good idea to replace them in some situations especially if the crown is over five years old. Most insurance companies will cover their portion of the cost then, which is usually at 50%. I hope I’ve given you enough information to help you to understand why they are replaced. Good luck with your procedure and I hope my advice has helped.

hi LINDA, enable ME FIRST clarify somewhat AS TO WHAT happens TO A teeth THAT HAD A ROOT CANAL. while the basis CANAL is performed, THE SMALL BLOOD VESSELS AND NERVE ARE ALL bumped off. those ARE had to maintain THE teeth moist FROM interior. WHAT THEN happens IS THAT THE teeth starts off TO DRY AND grow to be BRITTLE. the incorrect chew on the incorrect TIME would reason A ruin interior the teeth. subsequently why A CROWN is mentioned in a while. IF THE teeth isn't extraordinary floor FOR THE CROWN, THE CAP OR CROWN CAN COME OFF actually. 5 MONTHS WILL advise THAT THE teeth needs to be RE-floor FOR a clean CROWN, AS THIS recent shape won't BE sufficient. finally THE teeth WILL ultimately fall apart W/O A CROWN. plenty relies upon on the cost you place in this teeth. EXTRACTION IS an option, however the lacking teeth NOW has to get replaced via A BRIDGE. this means that the tooth TO the two area OF THE EXTRACTED teeth ought to additionally be floor FOR A BRIDGE. yet an alternate selection IS AN IMPLANT. coverage does not PAY FOR THIS. there is not any longer something TO BE ASHAMED OR EMBARRASSED approximately. it relatively is YOUR MOUTH, and you are the BOSS. purely MAKE an mentioned determination. stable success.

Not necessarily - it will eventually but normally a dentist will fill the hole with an amalgam filling and leave it for about a year to make sure it gives you no further problems before replacing a porcelain crown.

Answer 4

I got mine capped with porcelain, and it has lasted (without any damage) since 2003. You got to be careful though. Not to each chewing gums or subject it to hard(and i mean reallly hard) food stuffs...
