What You Need to Know About Dental Crowns

Dec 04, 2019

Are you having difficulties with your tooth’s shape and appearance? Worry not because at harbor view dental in Burlington we offer quality dental crown services. Before deciding the materials to be used on your crown, the following factors are considered:

  • The number of teeth that can be seen when you smile.
  • The color of the tooth
  • Location and function of the tooth
  • Position of the gum tissue
  • Your preference

Reasons as to why you may need a crown

If you have a weak tooth, worn down or cracked.

If you had a root canal treatment

If you have a cavity that is too large for a filling

If you wish to improve your smile by covering a badly shaped or discoloured tooth.

Steps of placing a crown

When placing a crown over a natural tooth several steps are involved. Normally it takes two dental visits to complete the treatment. Below are the steps to be followed.

  • Some portion of your tooth is filed down so that the crown can fit. Any form of decay is also removed. If there is a need for any additional tooth structure to support the crown the dentist may build up the core of the tooth.
  • A sample is made to showcase an exact model for the crown. This sample can be made from a mold or by scanning the tooth.
  • You will be given a temporary crown as you wait for the permanent crown to be ready. It normally takes less than two weeks. Your tooth may be too sensitive and cold with the temporary crown. You should avoid eating sticky foods at this time. If the dentist has special equipment you can get your new crown on the same day.
  • When the new crown is ready it is placed in your mouth by the dentist as necessary adjustments are also made.

Caring for Your Crowns

Even after getting dental crowns, you need to care for your teeth to ensure the treatment serves you well. A tooth with a crown can still break and the tooth under these crowns can still get cavities. To prevent cavities or damage to your clown you can do the following:

  • Ensure that you brush your teeth for at least twice a day.
  • Avoid bad habits such as chewing pens or using teeth to open bottles
  • Look for suitable and recommended oral products as per your dentist’s advice
  • See your dentist for regular examinations and teeth cleanings

Types of available crown material

Permanent crowns can be made from all metal, porcelain-fused-to-metal, all resin, or all ceramic.

Metals used in crowns include gold, palladium, nickel, or chromium. Metal crowns rarely chip or break, last the longest in terms of wear down, and only require a small amount of tooth to be removed. They can also withstand biting and chewing forces. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.

Porcelain-fused-to-metal dental crowns can be matched to the color of the teeth beside them. They have a more natural tooth color. However, sometimes the metal under the crown’s porcelain cap shows through as a dark line. Other drawbacks are that the crown’s porcelain portion can chip or break off and there is more wearing down of the teeth opposite them in the mouth. (The top and the bottom tooth that comes into contact when the mouth is closed.) These crowns can be a good choice for front or back teeth.

All-resin dental crowns are less expensive than other crown types. However, they wear down over time and are more likely to break than porcelain-fused-to-metal crowns.

All-ceramic or all-porcelain dental crowns provide the best natural color match than any other crown type. They are also a good choice for people with metal allergies. However, they are not as strong as porcelain-fused-to-metal crowns. They also may wear down the teeth opposite them in the mouth a little more than metal or resin crowns. All-ceramic crowns are a good choice for front teeth.

Pressed ceramic crowns to have a hard inner core. They replace the metal liner that is used in the all-ceramic crown-making process. Pressed ceramic crowns are capped with porcelain, which provides the best natural color match. They are also more long-lasting than an all-porcelain crown.
