Well, in reality, there is no difference. Patients have been asking this question for as long as I have been in practice and it just happened again. Over the years dentists have been using these two terms, caps and crowns, synonymously. At one time a cap was a term used just for front teeth to denote usually an all porcelain restoration. At the present time there is no real difference between the two terms.
A cap or crown is a full tooth covering. It is usually used when there is not enough tooth structure left to place either a filling (silver or tooth colored composite) or an inlay (a porcelain or similar material restoration made at the laboratory). A crown (cap) can be made of all metal, metal covered by porcelain, all porcelain or out of one of a number of new porcelain type materials such as Procera or Empress. In all cases, crowns (caps) cover the entire tooth and need to be either cemented or bonded in place.
Hope this helps to resolve the confusion.
