DOES A ROOT CANAL TREATED TOOTH NEED A CROWN?
Does your dentist recommend a crown over your root canal treated tooth? And just because he quotes a whopping amount for the crown u postpone the crown and possibly even do not care to do it? Here’s a reason why u should have listened to your dentist.
Why do need a crown after root canal treatment?
Root canal treatment is largely performed on teeth significantly affected by caries, multiple repeat restorations and/or fracture. Already structurally weakened, such teeth are often further weakened by the endodontic procedures designed to provide optimal access and by the restorative procedures necessary to rebuild the tooth. Loss of pulp of the tooth and hence the moisture, may also effect an alteration in tooth properties. It is therefore accepted that root canal treated teeth are weaker and tend to have a lower lifetime prognosis. They require special considerations for the final restoration, particularly where there has been extensive loss of tooth structure. Consequences of not fixing a full coverage crown on your root canal treated tooth include fracture of the tooth, hence making it untreatable.
What are the types of crowns available?
At Dr Ehab’s dental clinic, we have a range of options for placing a crown depending on the need for strength and aesthetics of the root canal treated tooth.
- Porcelain fused to metal (PFM)
These crowns are tooth colored crowns with a metal sub-structure. These types of dental crowns are ideal for both back and front teeth primarily because they are very durable and come with an appealing look. Disadvantages include breaking or chipping at the porcelain metal junction and metal showing right at the edge of the crown.
This type of crown is made from zirconia, a very strong material which is compatible with the human body. Zirconia is used in many other medical applications such as artificial joints and is known for its strength and durability.
Advantages are :
Strength: zirconia crowns last longer than other types of crowns.
Aesthetics: these crowns have an attractive translucent colour which blends in well with the other teeth.
Retain more of the existing tooth: minimal preparation is required which means more of the original tooth is preserved.
- E max/ empress
This is a type of all-ceramic crown with an appealing translucent colour which is combined with extra strength and durability. This crown is considered to be the best match with your own natural teeth. The transparent colour and lifelike shape ensures that it is unlikely to be noticed amongst your own natural teeth. They are strong and long lasting.
All crowns have advantages and disadvantages. Which type is best for you will be determined in part by your occlusion (how your teeth meet) and whether you grind your teeth. The final choice is up to you and your dentist. Keep smiling!
