After the root canal treatment, a permanent filling is placed followed by placement of a crown. The tooth becomes very weak and brittle following root canal therapy and thus the restoration with a filling and crown is necessary to provide structural strength and durability and to prevent tooth fracture.
For placing crown your tooth will be prepared so as to provide space for placement of crowns. There are different types of crowns available such as metal crowns, metal-ceramic crowns, metal-free zirconia crowns, etc.
Crown Over Root Canal Treated Teeth
Metal-free crowns are better than metal-ceramic or metal crowns. Zirconia crowns have the following advantages.
1. Aesthetics – It provides better aesthetics.
2. Radiopaque – It has the ability to be radiopaque in the x-rays.
3. Strength – Five times more strength than porcelain or porcelain fused to metal (PFM)
4. Durable and biocompatible
At least go for a metal-ceramic crown than to go without crowns.
The crown can prevent a fracture of the tooth which may result in the tooth being non-restorable(not fixable). This is because the tooth will not be able to properly restored, an extensive filling will fail, root canal treatment will fail and ultimately the tooth will be lost. So always go for a crown, if your tooth is severely
