Is a Crown Necessary After a Root Canal?
During a root canal procedure, the small, threadlike tissue in the tooth’s center – the diseased or damaged pulp — is removed. The remaining space is then cleaned, shaped, and filled. Though root canals save teeth from decay, they cannot restore teeth to their former strength. Sometimes a tooth needs a little reinforcement.
A dentist or endodontist might choose to place a dental crown after a root canal for several reasons. These include:
To strengthen a fragile tooth
A previous injury, the removed tissue, or the trauma of drilling can all leave a tooth more fragile after a root canal. Placing a dental crown can provide the strength it needs to last and prevent any future damage.
To prevent infections
An infected or injured tooth is automatically at higher risk for recontamination. A dental crown provides an extra layer of protection against infection so you can avoid an extraction.
To protect from sensitivity
A root canal can leave some nerves feeling extra sensitive to temperature. Get a dental crown to tolerate the heat or chill better.
To provide a natural-looking appearance
Without the pulp, a tooth might appear gray or deeply stained. Restore the whiter shade and match the surrounding teeth with a dental crown.
When Can You Get a Root Canal With No Crown?
Dental crowns provide some fantastic benefits. In fact, a study in the Journal of Endodontics found a 90% survival rate for teeth placed with crowns after a root canal procedure. However, a dental crown isn’t always necessary. Ask yourself some of these questions to see if you would benefit from a crown:
Where is the tooth located?
If the tooth receiving a root canal is in the back – so your molars or premolars — the chances are greater you’ll need a dental crown. This is because these teeth must withstand all the pressure of chewing and grinding, so they might require the extra strength a crown can provide. On the other hand, the front teeth — your canines and incisors — might be perfectly fine without a crown, depending on the level of excavation.
What is the condition of the tooth?
The more injured or infected the tooth, the greater likelihood that you will need a dental crown. If the dentist or endodontist must excavate a large amount of the tooth during the root canal procedure, you will probably need a crown to reinforce the tooth. Molars and premolars that maintain a large amount of tooth and are at low risk for fracture might still be suitable for filling-only restorations after a root canal.
Has this tooth been restored before?
Similarly, if the tooth has undergone several restoration procedures — including the root canal — it will most likely need a crown to maintain its appearance and function.
In the end, your dental professional will help you determine the best option for restoring a tooth after a root canal. If you’re worried about the cost or appearance of a crown, bring those concerns to your dental professional so you can work together to find the best solution for your smile.
