What Are Dental Crowns Used For?

Dental crowns are bonded to existing teeth or implants to completely cover or put a cap on a damaged tooth, improve its shape or appearance, or align a crooked tooth.

Dental crowns are created to be the same shape as the natural tooth it would cover. They go over a damaged tooth to restore its shape and size, strengthen it, and/or improve its appearance. When the crown is fitted, it encases the entire visible portion of a tooth that sits above the gum line.

It can also be placed on top of an implant to give it a tooth-like shape and structure to work properly. Porcelain or ceramic crowns can be created to match the colour of your natural teeth, though there are other materials that can be used, including gold and metal alloys, as well as acrylic and ceramic. These combinations are generally stronger than porcelain, and are mostly recommended for back teeth. Porcelain bonded to a metal shell is mostly used because it is both strong and neutral to the eye.

Your dentist may recommend a dental crown in a number of situations, including:

  1. To protect a weak tooth (such as one suffering from decay) and prevent it from breaking or to hold together parts of a cracked tooth

    If your tooth is excessively decayed or damaged for a simple filling, your dentist may recommend a crown to protect the remaining healthy portion. A portion of the tooth is removed to make room for the thickness of the crown.

  2. To restore a tooth that is already broken or severely worn down

    A fractured tooth, whether the breakage is big or small, can cause excruciating pain and other problems. A crown can help restore a damaged tooth by first removing the fractured portion, and then reshaping the tooth to protect microfractures from spreading and causing more pain.

  3. To cover a dental implant

    After a single tooth implant, your dentist may choose to restore the tooth with a crown that fits perfectly into the dental implant, providing you with a natural, stable replacement.

  4. To cover severely discoloured or misshapened teeth

    Any kind of damage to the teeth that reduces the enamel and shortens the teeth, such as teeth grinding, or severe discolouration, can be fixed with dental crowns. Crowns can be used to adjust the shape, size, and colour of your teeth while protecting them from decay due to the loss of enamel.

Finally, it is important to note that crowns provide the perfect way to preserve your natural teeth provided there is enough of healthy tooth left over after a procedure, allowing you restored function, look, and feel without the need for extraction.
