What is the difference between crowns and caps?

Crowns and caps are often used interchangeably in dentistry, but they can have slightly different connotations. A crown is a type of dental restoration that completely encases a tooth or implant to restore its shape, size, strength, and appearance. The term "cap" is sometimes used colloquially to refer to a crown, but it can also imply a less comprehensive covering. Ultimately, both serve to protect and restore damaged teeth.
