Crown
Crown often referred to as “cap” is a type of indirect dental restoration that is fabricated in our dental laboratory to mainly provide sound protection on a tooth and to replace missing tooth structure.
It completely encircles the tooth to protect the tooth from heavy forces of chewing.
If a tooth has a large filling or weakened tooth structure, crown often is the best choice of treatment to protect the tooth to provide durable strength and integrity.
Crown often can be used to enhance cosmetics by covering the discolouration and staining on the tooth. Porcelain crown can be beautifully colour matched to improve aesthetics.
When a tooth receives a root canal therapy, a dental crown is needed especially on a back tooth as the tooth becomes very weakened
