A dental crown is used to enhance the overall appearance of your teeth as well as to improve your oral health. It is basically a tooth-shaped cap that is placed over the tooth to restore its size, function, and shape. Read more to learn about the dental crown procedure and if you need one.
Different materials are used to make dental crowns, including porcelain fused to metal, metal alloys, ceramics, composite resin, and porcelain. Crowns are usually colored to match your natural teeth color. Your dentist will consider these factors to create the most suitable dental crowns for you:.
This step typically takes 50 to 90 minutes to complete. Then your dentist will build up the core of the tooth if the crown requires additional support.
After reshaping your tooth, your dentist will take its impression using a digital scanner, paste, or putty to create the crown. The firing process generally takes about minutes. After your dental crown is finished and has cooled, your dentist will inspect it and remove any remnants of the fabrication process.
They will then place it over your tooth to ensure it fits your tooth, as well as your bite. In some cases, minor adjustments may be made to make the crown fit better or more comfortably. Finally, the crown will be cemented in place and your appointment will be complete. This saves both the patient and the dentist time since a second appointment is no longer needed. If your dentist recommends a dental crown, ask them about having a same day crown placed.

Placing a temporary crown over the prepared tooth may seem like a cosmetic necessity, but in reality, the temporary crown is very important for a number of reasons. Some states and provinces allow dental assistants to make a temporary crown for your prepared tooth.
In some cases, the dentist will fabricate the temporary crown. Using the small impression taken prior to preparing the tooth for the crown, the dentist or assistant will fill the impression tray with an acrylic resin material that fits the color of your natural teeth. Then the dentist places it over the prepared tooth.
Once the material has set, generally after one to two minutes, the impression is removed from your mouth. The dentist shapes the temporary crown so that it fits your tooth and removes any rough edges. Once it is ready, a temporary cement is used to secure the temporary crown onto your prepared tooth. The dentist will check to make sure your teeth bite together correctly. They will also make sure there are no rough or sharp edges around the temporary crown.
Temporary crowns are very important. Because your dentist has removed a substantial amount of tooth structure from the prepared tooth, the temporary crown acts as a barrier, keeping the prepared tooth in its place.
Without a temporary crown, the prepared tooth can begin to shift. Any movement from the prepared tooth will prevent the permanent crown from fitting properly. In some cases, the prepared tooth can move so much that the permanent crown simply won't fit over the prepared tooth. If this happens, the final impression will be taken again and the crown will be sent back to the laboratory to be remade. Temporary crowns also keep a vital tooth protected.
If you had a root canal, there will be no feeling in the tooth. Vital teeth are a different case. Most of the enamel is removed from the tooth during the preparation stage, leaving exposed dentin. Without a temporary crown, your tooth would be extremely hypersensitive to temperature and pressure. A temporary cement that contains eugenol is generally used because of its calming effects on the nerve.
It is vital for you to follow the post-operative instructions given to you for wearing a temporary crown. If the temporary crown does come off your tooth, call your dentist immediately and book an appointment to have it re-cemented. It generally takes the dental laboratory roughly seven to 10 business days to make your permanent crown.
Your dentist will ensure you have your cementation appointment scheduled before you leave the office after your tooth preparation appointment. When you return to the dental office to have your permanent crown cemented, the dentist will begin the appointment by numbing the prepared tooth and surrounding tissues with local anesthetic.
Even though the tooth is already prepared, the dentist needs to thoroughly clean the tooth before cementing the permanent crown. If you had a root canal performed on the prepared tooth, you will likely not require any local anesthetic. Once the prepared tooth is completely numb, your dentist will remove the temporary crown from the tooth. All of the temporary cement is removed from the tooth, and the tooth is completely dried.
Your dentist will then try the permanent crown on the tooth. Using a piece of dental floss, your dentist will also check the contacts in between the crown and adjacent teeth to ensure there is an ideal contact between the teeth. Contacts that are too tight or no contact at all pose a problem for you in the long run. A contact that is too tight will cause problems for you when you floss your teeth.
No contact in between the teeth will allow food to become lodged in between the teeth causing the potential for tooth decay. If the contact is too tight, your dentist will reduce a small amount from the adjacent tooth, not the crown. In cases where there is no contact, it may be necessary for the crown to be sent back to the laboratory to be remade. When your dentist is satisfied with the fit of the crown, the final cementation process begins.
This process involves keeping your tooth completely isolated from any saliva or water in your mouth. Cotton rolls may be placed on both sides of the tooth to keep the area dry. When the tooth is isolated any dried, a desensitizing agent may be applied to the tooth.
The desensitizing agent will help with any postoperative tooth sensitivity. Your dentist will then place a bonding material onto the prepared tooth.
Some bonding agents require a curing light to set the material. Your dentist will place the crown on your tooth and remove some of the excess cement that squeezes out from underneath the crown. Depending on the cement chosen, a curing light may be used again to set the cement completely. Floss will be used to remove the excess cement from in between the teeth, and a dental scaler is used to remove excess cement from around the tooth and below the gumline.
Your dentist will wait approximately 10 minutes for the permanent cement to set. When ready, your dentist will then check how your teeth bite together. Any high spots on the crown will be reduced on the opposing tooth. It is very important to have the bite correct because a high bite can lead to tooth sensitivity and tooth pain.
