Dental crowns information for patients in Edmonton
What are Dental Crowns?
A crown is a type of dental restoration that entirely covers or ‘caps’ a damaged tooth or dental implant. They can be applied to front teeth and back teeth and are custom-made to fit comfortably in your mouth and are cemented in place as fixed prosthetic implements.
Crowns are typically used to:
- Improve the strength, shape, appearance or alignment of a damaged tooth
- Protect a weak tooth from fracturing
- Restore a fractured tooth
- Replace a filling when a large cavity threatens the health of a natural tooth
- Cover a dental implant or tooth that has undergone root canal treatment
- Hold a dental bridge in place
Ceramic and porcelain crowns can be matched to the natural colour of your teeth. In some instances, other materials such as gold and metal alloys are utilized.
The treatment process for a dental crown requires multiple appointments. During the first appointment, your tooth will be prepared for a crown. Your dentist will administer a local anesthetic in the gum tissue around the tooth to numb the area and prevent discomfort.
Next, your tooth may be isolated using a rubber dam apparatus which places a clamp on your tooth on the side of treatment and a rubber sheet placed around each individual teeth and anchored by the clamp and a metal frame. You tooth will be filed along the chewing surface and sides to make space for the crown. The amount that is filed will depend on the state of the tooth and the type of crown being inserted. In some instances, filling material may be used to build up the tooth to support the crown in part due to cavities on the tooth, fracture on the tooth or loosening of a previous restoration on the tooth.
Once the tooth is reshaped, putty is used to make an impression of your tooth, as well as the surrounding natural teeth to ensure the crown will not affect your bite. The impressions will be sent to a dental lab where the crown will be custom-made. You may receive a temporary crown in the interim to protect the prepared tooth.
During the second appointment, your temporary crown will be replaced with a permanent/final crown. Once again, a local anesthetic may be used if required. Your dentist will fit and cement the crown in place and ensure your bite has not been affected.
Risks & Complications
Crowns are an excellent restorative option for protecting weak or broken teeth. They can improve the appearance of your smile and last many years if cared for properly. However, there are some potential risks and complications with dental crowns.
You may experience discomfort or sensitivity upon receiving a new crown. Discomfort could be caused by the crown being placed too high, resulting in pressure on the crown and surrounding teeth. Also, if the crowned tooth still has a functional nerve within, it may be sensitive to hot or cold temperatures. Contact your dentist if you’re experiencing any type of pain or sensitivity.
There is a possibility you could experience bleeding around the site of the crown placement, as well as infection of the gums or mouth. Seek dental and/or medical treatment if the bleeding fails to cease or if you develop an infection.
Crowns can occasionally chip. If the chipping is extensive, your crown may need to be replaced.
Additionally, there is a chance your crown could loosen or fall off. The cement that holds the crown in place could wash out from under the crown, which may result in a loose or dislodged crown or open margin on the crown that can lead to decay of the underlying tooth. Contact your dentist immediately if you notice a loose feeling in your crown or if it falls off completely. You will receive specific instructions for how to care for the tooth and crown before seeing your dentist.
In rare cases, you may experience an allergic reaction to the metals or porcelain used in a crown or to the local anesthetic administered during the treatment process. If an allergic reaction occurs, follow the instructions of your dentist.
