Zirconia crowns are ideal for children who have damaged, cracked or broken their teeth. Whether the crown is placed over a primary (baby) tooth or a permanent one, you can feel confident that the restoration itself is durable and long-lasting. Zirconia is one of the hardest materials available, which makes it a great option for dental restorations. The crown is made to fit comfortably in your child’s mouth while simultaneously improving their overall appearance.
