A crown is like a helmet for a tooth.  Our teeth take a beating from a lifetime of chewing, not to mention clenching and grinding.  Crowning a tooth protects the tooth from fracturing when it has been weakened.  Fractures can be above the gums or below the gums. Teeth that fracture below the gums may be unable to be restored thus needing to be extracted.
 
The crown of the tooth may be compromised for different reasons.  One reason may be lack of tooth structure remaining.  A filling is only meant to fill a small hole and not replace the crown of the tooth. Root canalled teeth need to be crowned too. After a tooth has been root canal treated it becomes brittle and prone to breaking. 
 
Crowns are made of different materials.  They can be tooth coloured or gold or silver. Crowns can be completed in one or two appointments. Computer generated crowns (CAD-CAM) can be done in one visit.  Traditional lab fabricated crowns are done in two appointments. 
 
Your dentist will help you decide when a crown may be recommended and which type is best for your tooth.  Don’t to break a tooth! Call us at the Rideau dental centre for an appointment.

Do you have pain in your mouth? Are you sensitive to sweets, hot, or cold? Is it a sharp and fast pain or is it a dull ache that lasts.
 
Many people experience these sensations but ignore them, hoping they will magically disappear. Having these areas checked is very important. You may have a cavity or an infection around the root of the tooth, or it could be as simple as root exposure or a filling that needs to be adjusted.
 
Most people are afraid of the dreaded root canal... But they don't know what it is or why is it really necessary.
 
The root of the tooth houses the blood vessels and nerves.  Root canals may be considered necessary when bacteria enter the pulp from different sources. Some of these include bacteria entering the pulp through large cavities or leaky fillings, or cracks or trauma to the tooth.
 
A root canal treatment is the removal of a dead, injured or infected pulp. You are given local anesthetic so the procedure is painless. Your dentist will remove the pulp and clean out the canal before sealing the pulp canals. After your tooth has had a root canal treatment you need to discuss how to restore the crown of tooth with your dentist.
 
Please don't ignore what your tooth is telling you. Make sure to tell us about it at your next visit at the Rideau Dental Centre!
