Almost everyone is confronted with the placement of a dental crown at some point. But when do you have this type of prosthesis? Are there different types?
What is a dental crown?
A dental crown is a shell-shaped prosthesis that looks like a cap that is placed on a damaged, broken, worn or even devitalized tooth.
The dentist takes an exact impression of the tooth and sends it to the dental technician who, in return, will send a crown that fits the tooth exactly. After fitting, the crown will be bonded to the tooth without the need for anaesthesia.
Single or swivel crown?
There are 2 types of dental crowns: the simple crown or the crown on a pivot.
- The simple crown is used when a tooth has had a major decay, is broken or very damaged: the tooth is repaired using a reconstructive material (resin for example) and then a crown is placed on top of it.
- A crown with a post is used when the tooth is too damaged for a crown to be placed directly on top: in this case, the dentist places an inlay-core, a metal piece that will anchor itself in the root of the tooth with an upper part called a stump that reconstructs the visible part of the tooth. The crown can then be placed on top of this inlay core. This is, in fact, what used to be called teeth on pivots.
What type of crown should I choose?
It depends mainly on the aesthetic aspect.
There are crowns made of non-precious metal (nickel, chromium, etc.) or precious or semi-precious metal (gold, paladium, etc.): generally used for back teeth.
There are also ceramic teeth, either with a metal coping and ceramic exterior, or all-ceramic: ceramic is generally used for the front teeth since its colour resembles a real tooth.
It is important to inform the dentist of possible allergies, especially to nickel, before placing a crown.
Is the placement of a dental crown painful?
Most of the time, the placement of a crown goes smoothly, even if sometimes a little pain or a feeling of compression can be felt in the days following the placement: these inconveniences are generally only temporary.
Are dental crowns reimbursed by health insurance?
The installation of a crown is reimbursed very little by the Caisse primaire d’assurance maladie: $107.50, whereas it will cost you between $500 and $1,200 (the fees are free for this type of prosthesis, which explains these large price differences).
Some health insurance companies supplement this low reimbursement in part, so it is up to you to check with your own.
