Make an Appointment
One of the most versatile and widely used restorative dental treatments, a crown is placed to cover or “cap” a damaged tooth in its entirety.
What are Porcelain Crowns?
A crown sometimes referred to as cap are a covering that encases the entire tooth surface restoring it to its original shape and size. Crowns act as as a band around the tooth, reducing the effects of occlusal (biting) force, keeping the integrity of the tooth. Although there are several types of crowns, porcelain (tooth coloured crown) are the most popular, because they resemble your natural teeth. Porcelain crowns are made to match the shape, size, and colour or your teeth giving you a natural, long-lasting beautiful smile.They are highly durable and will last many years, but like most dental restorations, they may eventually need to be replaced.
Reasons for crowns:
A crown protects and strengthens tooth structure that cannot be restored with fillings or other types of restorations.
