When a tooth is badly broken or there is more filling than tooth a crown may be needed to restore the tooth to original condition.” Years ago crowns were only made of gold. Technology allowed the use of porcelain baked over gold to be used, beginning in the 60s. Later, porcelain was baked over “space-aged” metals with little or no gold content. Today we can do all porcelain crowns without ANY metal that are bonded onto the tooth and offer beauty as well as strength. crowns_page
