Often there are situations where the strength of the remaining tooth is diminished due to damage from large cavities, grinding, cracks, fractures or teeth treated with root canals. In these instances, a standard filling would inadequately address this loss in strength.
When Are Crowns Used and What Are They Made From?
For long-term protection to the tooth, and to allow the tooth to survive normal daily wear, a crown can be used to cover the tooth in its entirety and protect it from further damage. Crowns can be fabricated from many different materials such as porcelain, zirconia, gold, or a combination. Each material has its own benefits and drawbacks; your dentist can discuss with you which material would be most suitable for your tooth.
