If a tooth has more extensive decay, a dental crown may be the ideal aesthetic and functional restorative solution.  Choosing to have a crown placed can preserve the natural tooth, which is always the goal as preserving the natural teeth helps maintain the supporting bone structure and stability of the surrounding and adjacent teeth.  
Sometimes the final crown can be placed on the same day but other times a temporary crown will be placed while your final restoration is being created. 

There are four main types of dental crowns:
Ceramic – This type of crown is often used for teeth that are visible when smiling as they are made from a porcelain-based material that retains the look of your natural teeth.
Porcelain Fused to Metal – These crowns are known for their strength and durability while also allowing for a natural-looking restoration.
Gold Alloys – These may be used when more strength is needed, particularly for patients who grind their teeth at night.
Base Metal Alloys – These are strong and corrosion-resistant and are often used when there is less existing tooth structure available to support the crown restoration.
