Crowns (caps)

Teeth that have become weakened due to large restorations or root canals must be reinforced and protected to prevent them from deteriorating further. Teeth are subjected to tremendous forces during normal chewing and are prone to fracture and wear. Crowns are a means of restoring these weakened teeth and protecting them from further damage. There are many types of crowns ranging from gold to porcelain.

Teeth crowning procedure

The patient is given an anaesthetic to numb the region, preventing any discomfort during the procedure. A circumference of about 1.5 mm is "trimmed" from the surface of the tooth. The height of the tooth is also reduced by about 2mm, and then an impression of the tooth is taken using a putty-type material. This is sent to the lab for construction of a custom made crown by a dental technician. In the meantime a temporary restoration is placed on the tooth. The patient then re-presents about 2 weeks later for the insertion and cementation of the final crown. The crown is permanent and does not come off.

After your teeth crowning surgery

The numb feeling wears off the tooth after about 2 hours. The procedure is minimally invasive and the patient can go back to work or normal duties afterwards.

The long term outcome

Crowns do not last forever. They have a life expectancy of about 10 years, and the crown must be kept clean by brushing and flossing as the tooth underneath the crown is still prone to decay.

Teeth crowning risks

The right type of crown must be placed in the correct place in the mouth. Porcelain crowns are placed on front teeth for cosmetic procedures, however back teeth are best restored with gold crowns as these teeth are subjected to great forces during chewing and grinding. An incorrect crown in the wrong place is subject to fracture and failing.

Teeth crowning cost

The cost of the crown depends on the type of crown made and typical prices for teeth crowning range from $950-$2500.
