A dental crown is a tooth-shaped “cap” that is placed over a tooth — to cover the tooth to restore its shape and size, strength, and improve its appearance. The crowns, when cemented into place, fully encase the entire visible portion of a tooth that lies at and above the gum line.
The dentist will prepare the tooth to the ideal shape for the crown. This will involve removing a layer of the outer surface, leaving a strong inner core. The amount of the tooth removed will be the same as the thickness of the crown.
Once the tooth is shaped, the dental team will take an impression (mould) of the prepared tooth, one of the opposite jaw and possibly another to show the way you bite together.
The impressions will then be given to a dental technician, along with information about the shade to use and any other information they need.
