dental crowns
The dental crown is a capsule that protects a damaged or healthy tooth. It covers the part of the remaining tooth by reconstituting the coronal part, which preserves the tooth from new attacks. This can avoid its extraction and complete replacement.
It may be needed in the following cases:
After root canal treatment
A large filling in a tooth
A broken tooth
A discolored, misshapen or misaligned tooth
Crowns are made of various types of metals, porcelain or a ceramic-metal alloy. Brush and floss them like you do your natural teeth.

This involves artificially reconstructing the top of the damaged tooth. The crown can be simple or associated with an inlay-core, false stump fixed in the root of the tooth by a tenon on which the crown will be fixed.
If it requires cutting the tooth, the crown has the advantage of protecting it without being noticed. The length of stay required may vary depending on the number of crowns prescribed and any care that may accompany.
Stages of a "dental crown" intervention
Step 1
Your dentist takes the impression of the tooth to model a temporary crown. The latter protects the tooth until the permanent crown is ready; it may not have the same color and shape as the final crown.
2nd step
After administering a local anesthetic, your dentist carves out part of the natural tooth to make room for the crown.
Step 3
Then he takes an impression of the chipped tooth and the neighboring teeth. He places the temporary crown on the cut tooth before sending you home.
Step 4
The impression is sent to the laboratory where the permanent crown will be made to measure. It then serves as a model to cut and form the filling (or restoration).
Step 5
At the next visit, your dentist replaces the temporary crown with the permanent crown. He checks the fit, shape and color, then cements it in place, restoring the tooth to its original function and appearance.
Lifetime of a crown
A crown can last between 5 and 20 years. The lifespan depends mainly on oral hygiene, maintenance, and also oral habits. Grinding your teeth, chewing ice cream, or biting your nails are conditions that can cause a crown to fall out or even fracture.
If a crown is dislodged from its tooth without breaking, it can simply be put back in place with a cement provided that the tooth is not decayed. If a crown has a major fracture, it should ideally be redone. A minor fracture can sometimes be repaired by the dentist.
Maintenance of a crown
It must be remembered that although a crown cannot decay, the tooth underneath may be exposed to decay and periodontal disease. It is then necessary to maintain the good hygiene methods including the brushing of the teeth and the passage of the dental floss.
During routine visits to the dentist, the condition of the tooth, the condition of the gums, the condition of the crown and its adaptation are checked. It is advisable to do a routine examination every six months to check the general condition of the mouth and teeth.
