    Dental Crowns

    Dental crowns are caps placed on top of damaged teeth. Crowns are used to protect, cover and restore the shape of your teeth when fillings don’t solve the problem. Dental crowns can be made out of metals, porcelain, resin and ceramics. They typically don’t require special care over time other than regular good oral hygiene.

    Why would I need a dental crown?

    You may need a dental crown for several reasons, including:

    • Protecting a weak tooth (possibly from decay) from breaking or to keep the weak tooth together if parts of it are cracked.
    • Restoring a broken tooth or a severely worn down tooth.
    • Covering and supporting a tooth with a large filling and not much tooth remaining.
    • Holding a dental bridge in place.
    • Covering misshapen or severely discoloured teeth.
    • Covering a dental implant.
    • Covering a tooth that’s been treated with a root canal.

    How long do dental crowns last?

    On average, dental crowns last between 5-15 years. The life space of a crown can depend on the amount of “wear and tear” the crown is exposed to, how well you follow oral hygiene practices and personal mouth-related habits. These mouth-related habits can include things like:

    • Grinding or clenching your teeth.
    • Chewing ice.
    • Biting your fingernails.
    • Using your teeth to open packaging.

    Unfortunately, the teeth underneath the crown can still get damaged by bacteria, which causes cavities and tooth decay. That is why, even with a dental crown, it’s still vital to maintain proper oral hygiene and regular visits to your dentist for cleaning and check ups.

    A root canal (or what is actually root canal therapy) is not necessarily required in order to place a dental crown. A dental crown is often placed on a living tooth (a tooth that has not undergone root canal therapy). Crowns are often used on non-root-canal-treated teeth that are structurally compromised.

    Use a soft toothbrush to thoroughly clean the teeth. You can also add a fluoride rinse and fluoride toothpaste or gel to your cleaning regimen. Gently floss the veneers and bridges, being careful to avoid breakage. Finish with a mouthwash rinse to remove the bacteria that lead to tooth decay.
