1When restorative material forms the majority of the dental crown, the tooth will be quite fragile under biting force as the tooth substance is relatively thin. |
2This may lead to cusp fracture. |
3In severe cases the whole tooth may split into half. Tooth extraction will be unavoidable. |
4If the crack reaches the pulp chamber and injures the nerves and blood vessels, pain will be experienced and abscess will be possibly formed. |
5To avoid the consequences mentioned above....... |
6The tooth is trimmed until enough space is available for the crown to fit on. |
7The crown will be glued to the tooth and protecting it like a helmet. |
