Before performing any treatment, a dentist in Calgary will conduct an X-ray and examination on the tooth. During a secondary visit, anesthesia is given to the patient before the tooth is prepared. Once the tooth is reshaped, a dentist will take an impression of the tooth which will be sent to a dental lab. During this time, a temporary crown is worn by patients for protection purposes. Once the permanent crown is fitted, it is cemented on the tooth. With the proper care, a permanent crown can last up to fifteen years.
