Dental crown

A crown is a hollow artificial tooth that covers a damaged one: it restores its shape, appearance and function, and protects it from further damage. It may be needed after a root canal, after a large filling, or when a tooth has broken. An assessment confirms whether it is the right option.

What a crown is

A crown is a hollow artificial tooth that covers a damaged or decayed tooth. It restores the tooth and protects it from further damage. The appearance and function of a tooth covered by a crown are very close to those of a natural tooth.

A crown can also be used to cover a discoloured or misshapen tooth.

When a crown is used

Placing a crown may be necessary after root canal treatment, or when a tooth has had a large filling or has broken. In those cases it aims to restore the shape, appearance and function of the tooth.

Lifespan and care

Crowns are durable and generally last ten years or more when properly cared for. They need to be brushed and flossed like natural teeth.

They can, however, be more fragile than a natural tooth: it is better to avoid biting hard objects and not to use your teeth to open or cut anything.

When to seek care

Certain signs suggest a heavily restored tooth is reaching the limit of what it can take: a brief pain as you release your bite, a piece that breaks away, a visible crack, sensitivity that settles in.

It is better to have the tooth assessed before it breaks: a cracked tooth leaves more options than a fractured one. The assessment is what determines whether a crown is the appropriate option.

How the treatment works

The tooth is first prepared to receive the crown, then an impression is taken so the piece is made to the right shape and shade.

A temporary crown protects the tooth while the permanent one is made. At the next visit, the permanent crown is tried in, adjusted and cemented.

After the treatment

While the temporary crown is in place, it is better to avoid sticky and hard foods on that side: it is not held as firmly as the permanent one.

Once the crown is placed, care is the same as for a natural tooth: brushing and flossing, including where it meets the gum. Contact the clinic if the crown moves, comes loose, or if your bite feels off.

A dental crown covers and protects a tooth that is broken, cracked or too weakened for a filling to be enough. Often placed after a root canal or a large filling, it restores the shape, the appearance and the function of the tooth, and generally lasts ten years or more. If you have a cracked tooth or pain when biting, a prompt assessment keeps your options open. Our Repentigny clinic also welcomes patients from Charlemagne, Le Gardeur and L’Assomption.

Repair a damaged tooth

The treatments that aim to restore the shape and the function of an affected tooth.

  • A professional points out, on an anatomical tooth model, the cavity that a filling repairs.

    Dental filling

    A filling restores a tooth affected by decay or a small fracture. Faced with a cavity, the dentist may decide to monitor how it develops or to restore the tooth right away: significant decay left unrestored can deepen and cause pain. The choice of material depends on the condition of the tooth.

    Root canal treatment

    A root canal involves removing the infected, damaged or dead pulp from inside the tooth. When it succeeds, it makes it possible to keep the natural tooth rather than having it extracted, which keeps the other teeth from losing their alignment. An assessment determines whether the situation allows it.
